Healthcare organizations generate and collect large voluminous and heterogeneous information daily and DM helps to uncover some interesting patterns, which leads to the manual tasks elimination, easy data extraction directly from records, to save lives, to reduce the cost of medical services and to enable early detection of diseases. These patterns can help healthcare specialists to make forecasts, put diagnoses, and set treatments for patients in health facilities. This work overviews DM methods and main issues. Three case studies illustrate DM in healthcare applications: (i) In-Vitro Fertilization; (ii) Content-Based Image Retrieval (CBIR); and (iii) Organ transplantation." tags: - "Content-Based Image Retrieval" - "Health-Oriented Databases" - "pattern recognition" - "data mining" - "Patient monitoring" - "image processing" - "Computer vision" - "CBIR" researchr: "https://researchr.org/publication/de-JesusEstrelaEstrelaEstrelade-Jesusde-JesusEstrelaEstrela2016" cites: 17 citedby: 1 journal: "Oriental Journal Computer Science and Technology" volume: "9" number: "3" kind: "article" key: "de-JesusEstrelaEstrelaEstrelade-Jesusde-JesusEstrelaEstrela2016" - title: "Image database of low-altitude UAV flights with flight condition-logged for photogrammetry, remote sensing, and computer vision" author: - name: "de Figueiredo, Helosman Valente" link: "https://researchr.org/alias/de-figueiredo%2C-helosman-valente" - name: "Saotome, Osamu" link: "https://researchr.org/alias/saotome%2C-osamu" - name: "Shiguemori, Elcio H" link: "https://researchr.org/alias/shiguemori%2C-elcio-h" - name: "Filho, Paulo Silva" link: "https://researchr.org/alias/filho%2C-paulo-silva" - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" year: "2020" abstract: "The growth in the number of aerial images available is stimulating research and development of computational tools capable of extracting information from these image databases. However, developing a new computer vision (CV) software is complicated because many factors influence the extraction of information from aerial images, such as lighting, flight altitude, and optical sensors. The CV has been incorporated in most modern machines such as autonomous vehicles and industrial robots. The aim is to produce a high-quality image database of low-altitude Unmanned Aerial Vehicle (UAV) flights with flight condition-logged for photogrammetry, remote sensing, and CV. This work resulted in a collection of aerial images in the visible and thermal spectrum, and this set of images was captured in different schedules of the day, altitudes of flight, times of the year. The cameras are synchronised with the UAVs autopilot, and they were spatially and spectrally characterised in the laboratory. This research makes available low altitude aerial images of a region in Brazil to all community, with the precise flight and capture information, as well as additional features such as ground truth and georeferenced mosaic. Examples of the use of the database are shown for mosaic generation and development of CV algorithms for autonomous navigation of UAVs [1,2]. Furthermore, this database will serve as a benchmark for the development of the CV algorithms suited for autonomous navigation by images.

Abrupt changes in regular water distribution - such as shortage or inundation - may be catastrophic. To circumvent issues regarding overload and scarcity of water, huge sums of capital have to be invested and knowledge from several areas like hydrology and civil engineering can be applied to manage and allocate water. Since near ¾ of the Earth corresponds to oceans, water scarcity results from poor temporal and spatial water allocation as well as unsatisfactory quality to fulfill local needs. This makes water a restrictive factor for the progress of agriculture and industries. Existing information on water control systems is almost always insufficient leading to some critical situations. These unsatisfactory effects could have been evaded if enough hydrologic, geologic and climatologic data for planning had been readily available. This text aims at showing the relevance of remote sensing (RS) and Geographical Information Systems (GIS) techniques when it comes to acquire hydrologic data and to support operational as well as managerial hydrology. This work shows how image processing can be applied to help hydrology" links: "url": "http://books.google.com.br/books?hl=pt-BR\\&\\#38;lr=\\&\\#38;id=RV-SeH7ilP4C\\&\\#38;oi=fnd\\&\\#38;pg=PA398\\&\\#38;dq=\\%22vania+vieira+estrela\\%22\\&\\#38;ots=rqYtLvTQ1o\\&\\#38;sig=4korIoC4wc1S1byBqBHAdPfkckc" tags: - "control systems" - "data-flow analysis" researchr: "https://researchr.org/publication/da2011hyperspectral" cites: 21 citedby: 4 booktitle: "Sustainable Water Management in the Tropics and Subtropics and Case Studies in Brazil" publisher: "University of Kassel" isbn: "9788563337214" chapter: "HYPERSPECTRAL ANALYSIS OF REMOTELY SENSED IMAGES" kind: "inbook" key: "da2011hyperspectral" - title: "Super-Resolution in a Nutshell" author: - name: "Maria Aparecida de Jesus" link: "https://orcid.org/0000-0001-6428-9438" - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" - name: "Vania Estrela" link: "http://scholar.google.com/citations?user=-ZbglqgAAAAJ&hl=en" - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" - name: "Vania Vieira Estrela" link: "http://scholar.google.com/citations?user=-ZbglqgAAAAJ&hl=en" - name: "Vania Estrela" link: "http://scholar.google.com/citations?user=-ZbglqgAAAAJ&hl=en" - name: "Vania Vieira Estrela" link: "http://scholar.google.com/citations?user=-ZbglqgAAAAJ&hl=en" - name: "Vania Vieira Estrela" link: "http://scholar.google.com/citations?user=-ZbglqgAAAAJ&hl=en" - name: "Osamu Saotome" link: "http://academic.research.microsoft.com/Author/3476641/osamu-saotome?query=osamu%20saotome" - name: "others" link: "https://researchr.org/alias/others" year: "2016" researchr: "https://researchr.org/publication/de2016super" cites: 0 citedby: 0 booktitle: "Proceedings of the 2016 Brazilian Technology Symposium (BTSym 16)" kind: "inproceedings" key: "de2016super" - title: "Sub-pixel accuracy edge fitting by means of B-spline" author: - name: "Ricardo Lucas Bastos Breder" link: "http://lattes.cnpq.br/3742597671704110" - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" - name: "Joaquim Teixeira de Assis" link: "http://lattes.cnpq.br/7307238902576135" year: "2009" doi: "http://dx.doi.org/10.1109/MMSP.2009.5293265" links: doi: "http://dx.doi.org/10.1109/MMSP.2009.5293265" dblp: "http://dblp.uni-trier.de/rec/bibtex/conf/mmsp/BrederEA09" researchr: "https://researchr.org/publication/BrederEA09" cites: 0 citedby: 0 pages: "1-5" booktitle: "mmsp" kind: "inproceedings" key: "BrederEA09" - title: "PROCESSAMENTO DE IMAGENS ESTEREOSCOPICAS PARA USO EM GEOTECNIA" author: - name: "Sandro Roberto Fernandes" link: "http://academic.research.microsoft.com/Author/53603335/sandro-r-fernandes" - name: "Ivan de Araújo Medina" link: "http://www.eng.uerj.br/prof/8" - name: "Joaquim Teixeira de Assis" link: "http://lattes.cnpq.br/7307238902576135" - name: "Marcus P.

However, developing a new computer vision (CV) software is complicated because many factors influence the extraction of information from aerial images, such as lighting, flight altitude, and optical sensors. The CV has been incorporated in most modern machines such as autonomous vehicles and industrial robots. The aim is to produce a high-quality image database of low-altitude Unmanned Aerial Vehicle (UAV) flights with flight condition-logged for photogrammetry, remote sensing, and CV. This work resulted in a collection of aerial images in the visible and thermal spectrum, and this set of images was captured in different schedules of the day, altitudes of flight, times of the year. The cameras are synchronised with the UAVs autopilot, and they were spatially and spectrally characterised in the laboratory. This research makes available low altitude aerial images of a region in Brazil to all community, with the precise flight and capture information, as well as additional features such as ground truth and georeferenced mosaic. Examples of the use of the database are shown for mosaic generation and development of CV algorithms for autonomous navigation of UAVs [1,2]. Furthermore, this database will serve as a benchmark for the development of the CV algorithms suited for autonomous navigation by images.

Abrupt changes in regular water distribution - such as shortage or inundation - may be catastrophic. To circumvent issues regarding overload and scarcity of water, huge sums of capital have to be invested and knowledge from several areas like hydrology and civil engineering can be applied to manage and allocate water. Since near ¾ of the Earth corresponds to oceans, water scarcity results from poor temporal and spatial water allocation as well as unsatisfactory quality to fulfill local needs. This makes water a restrictive factor for the progress of agriculture and industries. Existing information on water control systems is almost always insufficient leading to some critical situations. These unsatisfactory effects could have been evaded if enough hydrologic, geologic and climatologic data for planning had been readily available. This text aims at showing the relevance of remote sensing (RS) and Geographical Information Systems (GIS) techniques when it comes to acquire hydrologic data and to support operational as well as managerial hydrology.

As a consequence two very important issues arise: the increased availability of new materials and the need for materials with better performance. Polymer blends are polymer systems originated from the physical mixture of two or more polymers and/or copolymers, without a high degree of chemical reactions between them. To be considered a blend, the compounds should have a concentration above 2% in mass of the second component (Hage & Pessan, 2001; Ihm & White, 1996). However, the commercial viability of new polymers has begun to become increasingly difficult, due to several factors. The advantages of polymer blends lie in the ability to combine existing polymers into new compositions obtaining in this way, materials with specific properties. This strategy allows for savings in research and development of new materials with equivalent properties, as well as versatility, simplicity, relatively low cost (Koning et al., 1998) and faster development time of new materials (Silva, 2011). Rossini (2005) mentions that economically and environmentally, a very viable alternative is to replace the recycling of pure polymers by mixtures of discarded materials. Mechanical recycling causes the breakdown of polymer chains, which impairs the properties of polymers. This degradation is directly proportional to the number of cycles of recycling. Therefore, the blend of two or more discarded polymers can be a realistic alternative, since it can result in materials with very interesting properties, at a low cost. Besides its inexpensiveness, this choice is also a smart solution to the reutilization of garbage. Postconsumption package disposal always occurs in a disorderly manner and without regard for the environment. The recycling process becomes increasingly more important and necessary to remediate environmental impact. According Pang et al. (2000) apud Marconcini & Ruvolo Filho (2006) polyolefins such as high density polyethylene (HDPE), low density polyethylene (LDPE) and polypropylene (PP) and polyesters such as poly (ethylene terephthalate) (PET) are classes of thermoplastics that have been widely used in packaging and constitute a large part of post-consumer waste. The recycling of these materials and their mechanical characterization anticipating the possibility of a new cycle of life in the form of new products is challenging, although technologically and environmentally correct (Marconcini & Ruvolo Filho, 2006). The polymer blends can be obtained basically in two ways (Rossini, 2005):  By dissolving the polymers in a good solvent, common to them, and subsequently letting the solvent evaporate; and  In a mixer where the working temperature is high enough to melt or mollify the polymeric components, without causing degradation of the same. According to Wessler (2007), the polymer blends may be miscible or immiscible. The miscibility is the most important property to be analyzed in a blend, given that all other system properties depend on the number of phases, their morphology and adhesion between them. The miscibility term is directly related to the solubility, i.e., a blend is miscible when the polymers dissolve in each other mutually (Silva, 2011). The immiscible between the various engineering polymers is a limiting factor for its production. Thus, it is necessary to use compatibilization agents for their production. Computational modeling has become increasingly popular. The main objective of models is to assist process optimization with minimal investment of time and resources for experimental work. Most techniques are classified into two main groups: physical models and statistical models as shown by Malinov & Sha (2003). Statistical methods are chosen according to research objectives. There are several multivariate analysis methods for purposes quite different from each other. The desired value and quality of one or more product characteristics can be obtained via experiment analysis and DOE. These methods help determining optimal settings and controllable factors of a process such as: temperature, pressure, amount of reagents, operating time, etc.. When compared to the method of trial and error, DOE also allows a reduction of the number of required tests, and savings in time, labor and money. An important application of DOE is the optimization of experimental formulations as, for example, the composition of mixtures. The formulation development is a fundamental part of the food industry, chemicals, plastics, rubber, paints, medicines, and the like. In materials science, it is important to understand the correlation between material processing, microstructure and properties that enable the optimization of process parameters and compositions of materials to achieve the desired combination of properties, according Malinov & Sha (2003). The problem presented here is to determine the fraction of each polymer blend component, and to determine the agent or, in some cases, an agents system, when it is necessary to use more than one compatibilizing agent. Thus, this text studies the effect of factors, for example, amount of polypropylene, additive type, and amount of additive in the composition of polymer blends, i.e., the optimal polymer blends formulation using factorial design." links: "url": "http://www.intechopen.com/books/principal-component-analysis-engineering-applications/methodology-for-optimization-of-polymer-blends-composition" tags: - "control systems" - "design science" - "rule-based" - "Recycling" - "operating system" - "Environmental Engineering " - "composition" - "design research" - "testing" - "type system" - "model-driven development" - "model-driven engineering" - "Engineering Design for Environment" - "Meta-Environment" - "process modeling" - "Sustainability" researchr: "https://researchr.org/publication/coelho2012methodology" cites: 32 citedby: 1 kind: "misc" key: "coelho2012methodology" - title: "Proceedings of the 3rd Brazilian Technology Symposium: Emerging Trends and Challenges in Technology" author: - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" - name: "Vania Vieira Estrela" link: "http://scholar.google.com/citations?user=-ZbglqgAAAAJ&hl=en" - name: "Vania Vieira Estrela" link: "http://scholar.google.com/citations?user=-ZbglqgAAAAJ&hl=en" - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" - name: "Vania Vieira Estrela" link: "http://scholar.google.com/citations?user=-ZbglqgAAAAJ&hl=en" - name: "Hermes Jose Loschi" link: "https://scholar.google.com.br/citations?user=EqKYim8AAAAJ&hl=pt-BR" - name: "Hermes Jose Loschi" link: "https://scholar.google.com.br/citations?user=EqKYim8AAAAJ&hl=pt-BR" - name: "Hermes Jose Loschi" link: "https://scholar.google.com.br/citations?user=EqKYim8AAAAJ&hl=pt-BR" - name: "Yuzo Iano" link: "https://publons.com/researcher/1301911/yuzo-iano/" - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" year: "2019" researchr: "https://researchr.org/publication/estrela2019proceedings" cites: 0 citedby: 0 howpublished: "Print, online" kind: "misc" key: "estrela2019proceedings" - title: "Blade Runner 2049 and the Quest for Industry 4.0" author: - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" - name: "E.

(?=?I) are investigated and formally stated in this paper, for the optical flow problem. Intuitively, this regularization scheme makes sense, but it is not common to encounter high-quality explanations from the engineering point of view.

We propose a new approach which allows us to deal with these issues within a common framework. Our approach is based on the use of a technique called Generalized Cross-Validation to estimate the best regularization scheme for a given pixel. In our model, the regularization parameter is a matrix whose entries can account for diverse sources of error. The estimation of the motion vectors takes into consideration local properties of the image following a spatially adaptive approach where each moving pixel is supposed to have its own regularization matrix.

Optimization tries to overcome the image acquisition limitations, the ill-posed nature of the SR problem, to facilitate content visualization and scene recognition. Particle swarm optimization (PSO) is a superb optimization algorithm used for all sorts of problems despite its tendency to be stuck in local minima. To handle ill-posedness, different PSO variants (hybrid versions) have been proposed trying to explore factors such as the initialization of the swarm, insertion of a constriction coefficient, mutation operators, and the use of an inertia weight.

However, developing a new computer vision (CV) software is complicated because many factors influence the extraction of information from aerial images, such as lighting, flight altitude, and optical sensors. The CV has been incorporated in most modern machines such as autonomous vehicles and industrial robots. The aim is to produce a high-quality image database of low-altitude Unmanned Aerial Vehicle (UAV) flights with flight condition-logged for photogrammetry, remote sensing, and CV. This work resulted in a collection of aerial images in the visible and thermal spectrum, and this set of images was captured in different schedules of the day, altitudes of flight, times of the year. The cameras are synchronised with the UAVs autopilot, and they were spatially and spectrally characterised in the laboratory. This research makes available low altitude aerial images of a region in Brazil to all community, with the precise flight and capture information, as well as additional features such as ground truth and georeferenced mosaic. Examples of the use of the database are shown for mosaic generation and development of CV algorithms for autonomous navigation of UAVs [1,2]. Furthermore, this database will serve as a benchmark for the development of the CV algorithms suited for autonomous navigation by images.

It relies on spatio-temporal brightness variations due to motion. Our proposed adaptive regularized approach deals with these issues within a common framework. It relies on the use of a data-driven technique called Mixed Norm (MN) to estimate the best motion vector for a given pixel. In our model, various types of noise can be handled, representing different sources of error. The motion vector estimation takes into consideration local image properties and it results from the minimization of a mixed norm functional with a regularization parameter depending on the kurtosis. This parameter determines the relative importance of the fourth norm and makes the functional convex. The main advantage of the developed procedure is that no knowledge of the noise distribution is necessary. Experiments indicate that this approach provides robust estimates of the optical flow." links: "url": "http://spiedl.aip.org/getabs/servlet/GetabsServlet?prog=normal\\&\\#38;id=PSISDG00596000000159603W000001\\&\\#38;idtype=cvips\\&\\#38;gifs=yes\\&\\#38;ref=no" tags: - "meta-model" - "data-flow" - "Meta-Environment" - "systematic-approach" researchr: "https://researchr.org/publication/citeulike%3A7598661" cites: 12 citedby: 1 kind: "inproceedings" key: "citeulike:7598661" - title: "Biologically Rationalized Computing Techniques For Image Processing Applications" author: - name: "Maria Aparecida de Jesus" link: "https://orcid.org/0000-0001-6428-9438" - name: "Maria de Jesus" link: "https://orcid.org/0000-0001-6428-9438" - name: "Maria Aparecida de Jesus" link: "https://orcid.org/0000-0001-6428-9438" - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" - name: "Osamu Saotome" link: "http://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4780730Y6" - name: "Osamu Saotome" link: "http://academic.research.microsoft.com/Author/3476641/osamu-saotome?query=osamu%20saotome" - name: "Dalmo Stutz" link: "https://www.researchgate.net/profile/Dalmo_Stutz" - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" - name: "Vania Vieira Estrela" link: "http://scholar.google.com/citations?user=-ZbglqgAAAAJ&hl=en" - name: "others" link: "https://researchr.org/alias/others" year: "2017" doi: "https://doi.org/10.1007/978-3-319-61316-1_14" abstract: "Super-resolution (SR) reconstructs a high-resolution (HR) image from a set of low-resolution (LR) pictures and restores an HR video from a group of neighboring LR frames.

Objective: Based on this, the present study aims to implement a DES (Discrete Event Simulation) based model. This model is called CBEDE (Coding of Bits for Entities by means of Discrete Events) and aims to assist SUS by categorizing a broad spectrum of health-related topics as well as improving the transmission of medical data. Methodology: DES is an effective tool to approach a wide variety of health care issues. This technique has been used to model concepts with a high-level of abstraction in a system, such as patients, nurses, doctors; can be applied from the exchange of emails on a clinical server to the transmission of data packets between devices connected in a hospital network, which also uses the queuing concept and can be used to manage patient data, medical staff, or same emergency departments, intensive care units, surgical procedures, outpatient clinics, ie, the entire extent of a healthcare system. Aiming to solve such problems, the present study implements a model CBEDE applied to a healthcare system, and advanced modulation format DQPSK in a simulation environment, the Simulink simulation environment of the MATLAB software, improving the transmission of data, through a pre-coding process of bits applying discrete events in the signal before the modulation process. This proposal brings a new approach for signal transmission. In this case, the transmission is performed in the discrete domain with the implementation of discrete entities in the bit generation process. This study aims to increase the information capacity for healthcare systems. Results: Through simulations the model without the proposal consumed 55.5MB which in contrast the proposal had 28.82MB of consumption, in MB (Megabytes). Being the differential of this research the use of discrete events applied in the physical layer of a transmission medium, the bit itself, being this a low-level of abstraction, the results show better computational performance related to memory utilization and to the compression of the information, showing an improvement of 92.6%. Conclusion: Patients awaiting consultation with a medical specialist, in the context of a system interconnected between hospitals (which nowadays this is already reality). However the systems currently used are slow and consume a lot of system memory, facilitating crashes. With exchange patient data and medical consultations with each other, such scheduling of consultations may become more effective. This demonstrates that the CBEDE has great potential in the improvement of the hospital services. This potential of improvement of already existing processes can increase the performance of communication response between all the devices in the hospital system, because the flow of data will consume fewer resources and, therefore, can improve the interactions between doctor and patient.

In up to date research, the deformable contour is represented via B-spline snakes, which allows local control, concise depiction, and the use of fewer parameters. The estimation of edges with sub-pixel accuracy via a global B-spline depiction depends on determining the edge according to a Maximum Likelihood (ML) agenda and using the observed information likelihood. This practice guarantees that outliers present in data will be cleaned out. The data likelihood is calculated as a result of the observation model comprising both orientation and position data.

As a consequence two very important issues arise: the increased availability of new materials and the need for materials with better performance. Polymer blends are polymer systems originated from the physical mixture of two or more polymers and/or copolymers, without a high degree of chemical reactions between them. To be considered a blend, the compounds should have a concentration above 2% in mass of the second component (Hage & Pessan, 2001; Ihm & White, 1996). However, the commercial viability of new polymers has begun to become increasingly difficult, due to several factors. The advantages of polymer blends lie in the ability to combine existing polymers into new compositions obtaining in this way, materials with specific properties. This strategy allows for savings in research and development of new materials with equivalent properties, as well as versatility, simplicity, relatively low cost (Koning et al., 1998) and faster development time of new materials (Silva, 2011). Rossini (2005) mentions that economically and environmentally, a very viable alternative is to replace the recycling of pure polymers by mixtures of discarded materials. Mechanical recycling causes the breakdown of polymer chains, which impairs the properties of polymers. This degradation is directly proportional to the number of cycles of recycling. Therefore, the blend of two or more discarded polymers can be a realistic alternative, since it can result in materials with very interesting properties, at a low cost. Besides its inexpensiveness, this choice is also a smart solution to the reutilization of garbage. Postconsumption package disposal always occurs in a disorderly manner and without regard for the environment. The recycling process becomes increasingly more important and necessary to remediate environmental impact. According Pang et al. (2000) apud Marconcini & Ruvolo Filho (2006) polyolefins such as high density polyethylene (HDPE), low density polyethylene (LDPE) and polypropylene (PP) and polyesters such as poly (ethylene terephthalate) (PET) are classes of thermoplastics that have been widely used in packaging and constitute a large part of post-consumer waste. The recycling of these materials and their mechanical characterization anticipating the possibility of a new cycle of life in the form of new products is challenging, although technologically and environmentally correct (Marconcini & Ruvolo Filho, 2006). The polymer blends can be obtained basically in two ways (Rossini, 2005):  By dissolving the polymers in a good solvent, common to them, and subsequently letting the solvent evaporate; and  In a mixer where the working temperature is high enough to melt or mollify the polymeric components, without causing degradation of the same. According to Wessler (2007), the polymer blends may be miscible or immiscible. The miscibility is the most important property to be analyzed in a blend, given that all other system properties depend on the number of phases, their morphology and adhesion between them. The miscibility term is directly related to the solubility, i.e., a blend is miscible when the polymers dissolve in each other mutually (Silva, 2011). The immiscible between the various engineering polymers is a limiting factor for its production. Thus, it is necessary to use compatibilization agents for their production. Computational modeling has become increasingly popular. The main objective of models is to assist process optimization with minimal investment of time and resources for experimental work. Most techniques are classified into two main groups: physical models and statistical models as shown by Malinov & Sha (2003). Statistical methods are chosen according to research objectives. There are several multivariate analysis methods for purposes quite different from each other. The desired value and quality of one or more product characteristics can be obtained via experiment analysis and DOE. These methods help determining optimal settings and controllable factors of a process such as: temperature, pressure, amount of reagents, operating time, etc.. When compared to the method of trial and error, DOE also allows a reduction of the number of required tests, and savings in time, labor and money. An important application of DOE is the optimization of experimental formulations as, for example, the composition of mixtures. The formulation development is a fundamental part of the food industry, chemicals, plastics, rubber, paints, medicines, and the like. In materials science, it is important to understand the correlation between material processing, microstructure and properties that enable the optimization of process parameters and compositions of materials to achieve the desired combination of properties, according Malinov & Sha (2003). The problem presented here is to determine the fraction of each polymer blend component, and to determine the agent or, in some cases, an agents system, when it is necessary to use more than one compatibilizing agent. Thus, this text studies the effect of factors, for example, amount of polypropylene, additive type, and amount of additive in the composition of polymer blends, i.e., the optimal polymer blends formulation using factorial design." links: "url": "http://www.intechopen.com/books/principal-component-analysis-engineering-applications/methodology-for-optimization-of-polymer-blends-composition" tags: - "control systems" - "design science" - "rule-based" - "Recycling" - "operating system" - "Environmental Engineering " - "composition" - "design research" - "testing" - "type system" - "model-driven development" - "model-driven engineering" - "Engineering Design for Environment" - "Meta-Environment" - "process modeling" - "Sustainability" researchr: "https://researchr.org/publication/coelho2012methodology" cites: 32 citedby: 1 kind: "misc" key: "coelho2012methodology" - title: "Health 4.0 as an Application of Industry 4.0 in Healthcare Services and Management" author: - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" - name: "Vania Vieira Estrela" link: "http://scholar.google.com/citations?user=-ZbglqgAAAAJ&hl=en" - name: "Vania Vieira Estrela" link: "http://scholar.google.com/citations?user=-ZbglqgAAAAJ&hl=en" - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" - name: "Vania Estrela" link: "http://scholar.google.com/citations?user=-ZbglqgAAAAJ&hl=en" - name: "Vania Vieira Estrela" link: "http://scholar.google.com/citations?user=-ZbglqgAAAAJ&hl=en" - name: "Ana Carolina Borges Monteiro" link: "https://publons.com/researcher/1546021/ana-carolina-borges-monteiro/" - name: "Ana Carolina Borges Monteiro" link: "https://scholar.google.com.br/citations?user=3g7F2KYAAAAJ&hl=pt-BR" - name: "Ana Carolina Borges Monteiro" link: "https://scholar.google.com.br/citations?user=3g7F2KYAAAAJ&hl=pt-BR" year: "2019" abstract: "Industry 4.0 allows both customization and virtualization through different domains.

However, in the presence of noise, it becomes an il-posed problem that requires regulation. In the past, regularization for pel-recursive estimations was addressed in an ad-hoc manner. In this paper, a Bayesian estimation framework is used to deal with this issue. More specifically, motion vectors and regularization parameters are estimated in an iterative fashion by means of the Expectation- Maximization (EM) algorithm and a Gaussian data model. The proposed algorithm utilizes the local image properties to regularize the motion vector estimates following a spatially adaptive approach.

Transmedia Educational Environments (TECs) can help engage students in such subjects, and it is evident that the learner's attention span is longer and more focused when students employ mobile devices and other technologies than when they were not. Transmedia (TM) storytelling can render quotidian life as a vigorous constructivist didactic tool. Up to now, most of the efforts within classrooms are related to elementary school. The digital farm project introduces several class activities connected to the protagonist's universe and a real-life rural community. The instructor can handle a multitude of optimization problems learners can relate to and solve them. The class and the instructor can interact with other subjects like programming and application development. In Brazil, this is paramount due to the high levels of anxiety felt by engineering students.

It is common to introduce a priori information in the estimation process. Improvement can be achieved via a deformable model such as the snake model. In recent works, the deformable contour is modeled by means of B-spline snakes which allows local control, concise representation, and the use of fewer parameters. The estimation of the sub-pixel edges using a global B-spline model relies on the contour global determination according to a maximum likelihood framework and using the observed data likelihood. This procedure guarantees that the noisiest data will be filtered out. The data likelihood is computed as a consequence of the observation model which includes both orientation and position information. Comparative experiments of this algorithm and the classical spline interpolation have shown that the proposed algorithm outperforms the classical approach for Gaussian and Salt & Pepper noise." researchr: "https://researchr.org/publication/estrela2009sub" cites: 22 citedby: 1 pages: "1-5" booktitle: "Multimedia Signal Processing, 2009.

Anything but reduced human monitoring became impossible by means of its physical and economic implications, and an advance towards an automated surveillance becomes the only way out. When it comes to a computer vision system, automatic video event comprehension is a challenging task due to motion clutter, event understanding under complex scenes, multi-level semantic event inference, contextualization of events and views obtained from multiple cameras, unevenness of motion scales, shape changes, occlusions and object interactions among lots of other impairments. In recent years, state-of-the-art models for video event classification and recognition include modeling events to discern context, detecting incidents with only one camera, low-level feature extraction and description, high-level semantic event classification and recognition. Even so, it is still very burdensome to recuperate or label a specific video part relying solely on its content. Principal component analysis (PCA) has been widely known and used, but when combined with other techniques such as the expectation-maximization (EM) algorithm its computation becomes more efficient. This chapter introduces advances associated to the concept of Probabilistic PCA (PPCA) analysis [Tipping et al., 1999)] by of video event understanding technologies. The PPCA model-based method results from the combination of a linear model and the EM algorithm in an iterative fashion in order to determine a principal subspace (PS). Thus, additional work may be needed to find precise principal eigenvectors of the data covariance matrix, with no rotational uncertainty. Kernel principal component analysis (KPCA) is a nonlinear PCA extension that relies on the kernel trick. It has received immense consideration for its value in nonlinear feature mining and other applications. On the other hand, the main drawback of the standard KPCA is that the huge amount of computation required, and the space needed to store the kernel matrix. KPCA can be viewed as a primal space problem with samples created via incomplete Cholesky decomposition. Therefore, all the efficient PCA algorithms can be easily adapted into KPCA. Furthermore, KPCA can be extended to a mixture of local KPCA models by applying the mixture model to probabilistic PCA in the primal space. The theoretical analysis and experiments can shed light onthe performance of the proposed methods in terms of computational efficiency and storage space, as well as recognition rate, especially when the number of data points n is large. By considering KPCA from a probabilistic point of view with the help of the EM algorithm, the computational load can be alleviated, but there still exists a rotational ambiguity with the resulting algorithm implementation. To unravel this intricacy, a constrained EM algorithm for KPCA (and PCA) was formulated founded on a coupled probability model. This brings in advantages related to many factors such as the necessary precision of extracted components, the number of the separated smaller data sets (which is usually empirically set), and the data to be processed. As a generic methodology, another thread of speeding up kernel machine learning is to seek a low-rank approximation to the kernel matrix. Since, as noted by several researchers, the spectrum of the kernel matrix tends to decay rapidly, the low-rank approximation often achieves satisfactory precision. This chapter also aims at looking closely to ways and metrics in order to evaluate these less intensive EM implementations of PCA and KPCA.

As math intensifies, the corresponding attention span decreases. Transmedia Educational Environments (TECs) can help engage students in such subjects, and it is evident that the learner's attention span is longer and more focused when students employ mobile devices and other technologies than when they were not. Transmedia (TM) storytelling can render quotidian life as a vigorous constructivist didactic tool. Up to now, most of the efforts within classrooms are related to elementary school. The digital farm project introduces several class activities connected to the protagonist's universe and a real-life rural community. The instructor can handle a multitude of optimization problems learners can relate to and solve them. The class and the instructor can interact with other subjects like programming and application development.

Its practices permit industries and other sectors to become service providers. Health 4.0 customers comprise patients in addition to caretakers (both formal and non-formal) with increasing individualization and personalization as a client service. This work investigates the Health 4.0 framework. This standard involves the applicability and scalability of Industry 4.0 to healthcare and pharmaceutical domains. The manufacturing and deployment of health-oriented items must address the design practices and technology. Concepts like cloud computing, smart use of green energy, big data, new wireless networks forms and the Internet of Things (IoT).

Markers are used in order to trace gradients of deformation over a sample and study other mechanical properties. Image processing and video sequence analysis can be a very powerful investigation tool and this paper shows preliminary results from its use on microtectonics. The proposed algorithm is a combination of two well-known approaches: feature extraction and block matching.

Since the signals transmitted on real-world channels are highly compressed, regardless of cause, the quality of images reconstructed from any corrupted data can be very unsatisfactory.

It demands accessible data in medical archives and from medical equipment, to infer meaning after some processing. A problem similar in some sense to the target image can aid clinicians. CBIR complements text-based retrieval and improves evidence-based diagnosis, administration, teaching, and research in healthcare. It facilitates visual/automatic diagnosis and decision-making in real-time remote consultation/screening, store-and-forward tests, home care assistance and overall patient surveillance.

TLS method solves an inconsistent system Gu=z , with G and z in error due to temporal/spatial derivatives, and nonlinearity, while the Ordinary Least Squares (OLS) model has noise only in z. Sources of difficulty involve the non-stationarity of the field, the ill-posedness, and the existence of noise in the data. Three ways of applying the TLS with different noise conjectures to the end problem are observed. First, the classical TLS (cTLS) is introduced, where the entries of the error matrices of each row of the augmented matrix [G;z] have zero mean and the same standard deviation. Next, the Generalized Total Least Squares (GTLS) is defined to provide a more stable solution, but it still has some problems. The Generalized Scaled TLS (GSTLS) has G and z tainted by different sources of additive zero-mean Gaussian noise and scaling [G;z] by nonsingular D and E, that is, D[G;z]E makes the errors iid with zero mean and a diagonal covariance matrix. The scaling is computed from some knowledge on the error distribution to improve the GTLS estimate. For moderate levels of additive noise, GSTLS outperforms the OLS, and the GTLS approaches. Although any TLS variant requires more computations than the OLS, it is still applicable with proper scaling of the data matrix." researchr: "https://researchr.org/publication/de-JesusEstrelaEstrelaEstrelade-Jesusde-JesusEstrelaEstrela2017" cites: 39 citedby: 2 journal: "Oriental Journal of Computer Science and Technology" volume: "10" number: "3" kind: "article" key: "de-JesusEstrelaEstrelaEstrelade-Jesusde-JesusEstrelaEstrela2017" - title: "On improving sub-pixel accuracy by means of B-spline" author: - name: "Sandro Roberto Fernandes" link: "https://www.researchgate.net/profile/Sandro_Fernandes" - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" - name: "Osamu Saotome" link: "http://academic.research.microsoft.com/Author/3476641/osamu-saotome?query=osamu%20saotome" - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" year: "2014" month: "oct" doi: "10.1109/ist.2014.6958448" abstract: "Local perturbations nearby contours strongly perturb the final result of processing remotely sensed images (RSI).

The problem of blind signal separation was solved in a wavelet domain. The main idea behind this approach is that the mixing signal can be decomposed into a sum of uncorrelated and/or independent sub-bands using the wavelet transform. In the beginning, the observed signal is prewhitened in the time domain then, the initial separation matrix will be estimated from second order statistics decorrelation method in the wavelet domain. The estimating matrix will be used as an initial separating matrix in the higher order statistics method in order to estimate the final separation matrix. The algorithm was tested using natural images.

Optimization tries to overcome the image acquisition limitations, the ill-posed nature of the SR problem, to facilitate content visualization and scene recognition. Particle swarm optimization (PSO) is a superb optimization algorithm used for all sorts of problems despite its tendency to be stuck in local minima. To handle ill-posedness, different PSO variants (hybrid versions) have been proposed trying to explore factors such as the initialization of the swarm, insertion of a constriction coefficient, mutation operators, and the use of an inertia weight. Hybridization involves combining two (or more) techniques wisely such that the resultant algorithm contains the good characteristics of both (or all) the methods. Interesting hybridization techniques include many local and global search approaches. Results for the SR reconstruction of still and video images are presented for the PSO and the HPSO algorithms." links: doi: "https://doi.org/10.1007/978-3-319-61316-1_14" researchr: "https://researchr.org/publication/de2018super" cites: 44 citedby: 0 pages: "317-337" booktitle: "Biologically Rationalized Computing Techniques For Image Processing Applications" volume: "25" publisher: "Lecture Notes in Computational Vision and Biomechanics (LNCVB), Springer Cham, Online ISBN 978-3-319-61316-1, Print ISBN 978-3-319-61315-4, doi: 10.1007/978-3-319-61316-1\\_14, https://link.springer.com/chapter/10.1007/978-3-319-61316-1\\_14" kind: "incollection" key: "de2018super" - title: "Hierarchically Structured Bounding Boxes as an Aid for Cartography and Photogrammetry" author: - name: "Marcos Henrique da Silva Bassani" link: "http://academic.research.microsoft.com/Author/42688555/m-h-da-silva-bassani" - name: "Vania V Estrela" link: "http://academic.research.microsoft.com/Author/3361386" - name: "M.

It quickly isolates contour pieces that may belong to areas under risk. In real time applications, where the test for boundary changes is made in each time step, this is very important for studying the evolution of geotechnical phenomena and handling smooth curves as well as polygonal approximations. HSOBB introduces some noise filtering as well. It is a good option to more classical procedures, since it is able of dealing with a wide range of practical problems. Edges or abrupt jumps in contours may be enhanced by the use of different types of wavelet transform. Additional performance enhancements can be accomplished if noise is not assumed to be Gaussian, since commonly used detectors may have other types of noise ([12], [14], [15]), and may be subject to nonlinear distortions. An algorithm to detect exact interference for general and polygonal models was introduced. It pre-computes a hierarchical model representation using tight fitting OBB trees. At runtime, it goes across two such trees and tries to find overlaps among OBBs based on the separating axis theorem. In particular, it can robustly and accurately detect contacts between large complex geometries.

It is common to introduce a priori information in the estimation process. Improvement can be achieved via a deformable model such as the snake model. In recent works, the deformable contour is modeled by means of B-spline snakes which allows local control, concise representation, and the use of fewer parameters. The estimation of the sub-pixel edges using a global B-spline model relies on the contour global determination according to a maximum likelihood framework and using the observed data likelihood. This procedure guarantees that the noisiest data will be filtered out. The data likelihood is computed as a consequence of the observation model which includes both orientation and position information. Comparative experiments of this algorithm and the classical spline interpolation have shown that the proposed algorithm outperforms the classical approach for Gaussian and Salt & Pepper noise." researchr: "https://researchr.org/publication/estrela2009sub" cites: 22 citedby: 1 pages: "1-5" booktitle: "Multimedia Signal Processing, 2009.

The simulation environment employs a pre-coding process of bits based on the application of a technique relying on discrete events and signals before the modulation process. The signal transmission on the channel occurs in the discrete domain with the implementation of discrete entities in the process of bit generation applied at a low level of abstraction in a wireless telecommunication system. The simulation considered the advanced differential binary phase shift keying (DBPSK) as the modulation format for signal transmission in an AWGN channel, using different hardware platforms and in the studies. The results show improvements ranging from 9 to 35% in memory utilization, related to information compression, in the context of the research." links: doi: "https://doi.org/10.1007/978-3-030-16053-1_11" researchr: "https://researchr.org/publication/padilha2018betterment" cites: 20 citedby: 0 pages: "115-130" booktitle: "Proceedings of the 4th Brazilian Technology Symposium (BTSym'18).

This paper presents an approach where the optical flow between frames of video sequences is estimated according to a pel-recursive strategy through the use of a principal component regression (PCR). This is a simple choice when it comes to treat mixtures of motion vectors due to the fact that it is not essential to have too much knowledge on their statistical properties (although they are supposed to be normal). Local image properties are taken into consideration in order to estimate the 2D motion. The main advantages of the developed procedure are: ( i) the noise distribution is not used directly; and (ii) the types of motion present in neighborhood can be identified, so that a discriminant-type of test can be performed. Preliminary experiments indicate that this approach provides robust estimates of the optical flow." links: "url": "http://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.170.1132" tags: - "testing" - "systematic-approach" researchr: "https://researchr.org/publication/citeulike%3A11962120" cites: 0 citedby: 0 booktitle: "X EMC - ENCONTRO DE MODELAGEM COMPUTACIONAL - 2007" kind: "inproceedings" key: "citeulike:11962120" - title: "HYPERSPECTRAL ANALYSIS OF REMOTELY SENSED IMAGES " author: - name: "F.

Abrupt changes in regular water distribution - such as shortage or inundation - may be catastrophic. To circumvent issues regarding overload and scarcity of water, huge sums of capital have to be invested and knowledge from several areas like hydrology and civil engineering can be applied to manage and allocate water. Since near ¾ of the Earth corresponds to oceans, water scarcity results from poor temporal and spatial water allocation as well as unsatisfactory quality to fulfill local needs. This makes water a restrictive factor for the progress of agriculture and industries. Existing information on water control systems is almost always insufficient leading to some critical situations. These unsatisfactory effects could have been evaded if enough hydrologic, geologic and climatologic data for planning had been readily available. This text aims at showing the relevance of remote sensing (RS) and Geographical Information Systems (GIS) techniques when it comes to acquire hydrologic data and to support operational as well as managerial hydrology.

However, developing a new computer vision (CV) software is complicated because many factors influence the extraction of information from aerial images, such as lighting, flight altitude, and optical sensors. The CV has been incorporated in most modern machines such as autonomous vehicles and industrial robots. The aim is to produce a high-quality image database of low-altitude Unmanned Aerial Vehicle (UAV) flights with flight condition-logged for photogrammetry, remote sensing, and CV. This work resulted in a collection of aerial images in the visible and thermal spectrum, and this set of images was captured in different schedules of the day, altitudes of flight, times of the year. The cameras are synchronised with the UAVs autopilot, and they were spatially and spectrally characterised in the laboratory. This research makes available low altitude aerial images of a region in Brazil to all community, with the precise flight and capture information, as well as additional features such as ground truth and georeferenced mosaic. Examples of the use of the database are shown for mosaic generation and development of CV algorithms for autonomous navigation of UAVs [1,2]. Furthermore, this database will serve as a benchmark for the development of the CV algorithms suited for autonomous navigation by images.

It quickly isolates contour pieces that may belong to areas under risk. In real time applications, where the test for boundary changes is made in each time step, this is very important for studying the evolution of geotechnical phenomena and handling smooth curves as well as polygonal approximations. HSOBB introduces some noise filtering as well. It is a good option to more classical procedures, since it is able of dealing with a wide range of practical problems. Edges or abrupt jumps in contours may be enhanced by the use of different types of wavelet transform. Additional performance enhancements can be accomplished if noise is not assumed to be Gaussian, since commonly used detectors may have other types of noise ([12], [14], [15]), and may be subject to nonlinear distortions. An algorithm to detect exact interference for general and polygonal models was introduced. It pre-computes a hierarchical model representation using tight fitting OBB trees. At runtime, it goes across two such trees and tries to find overlaps among OBBs based on the separating axis theorem. In particular, it can robustly and accurately detect contacts between large complex geometries.

TLS method solves an inconsistent system Gu=z , with G and z in error due to temporal/spatial derivatives, and nonlinearity, while the Ordinary Least Squares (OLS) model has noise only in z. Sources of difficulty involve the non-stationarity of the field, the ill-posedness, and the existence of noise in the data. Three ways of applying the TLS with different noise conjectures to the end problem are observed. First, the classical TLS (cTLS) is introduced, where the entries of the error matrices of each row of the augmented matrix [G;z] have zero mean and the same standard deviation. Next, the Generalized Total Least Squares (GTLS) is defined to provide a more stable solution, but it still has some problems. The Generalized Scaled TLS (GSTLS) has G and z tainted by different sources of additive zero-mean Gaussian noise and scaling [G;z] by nonsingular D and E, that is, D[G;z]E makes the errors iid with zero mean and a diagonal covariance matrix. The scaling is computed from some knowledge on the error distribution to improve the GTLS estimate. For moderate levels of additive noise, GSTLS outperforms the OLS, and the GTLS approaches. Although any TLS variant requires more computations than the OLS, it is still applicable with proper scaling of the data matrix." researchr: "https://researchr.org/publication/de-JesusEstrelaEstrelaEstrelade-Jesusde-JesusEstrelaEstrela2017" cites: 39 citedby: 2 journal: "Oriental Journal of Computer Science and Technology" volume: "10" number: "3" kind: "article" key: "de-JesusEstrelaEstrelaEstrelade-Jesusde-JesusEstrelaEstrela2017" - title: "Adaptive mixed norm optical flow estimation" author: - name: "Vania Vieira Estrela" link: "http://academic.research.microsoft.com/Author/3361386/vania-v-estrela" - name: "Matthias Otto Franz" link: "http://academic.research.microsoft.com/Author/471957/matthias-o-franz" - name: "Ricardo Tadeu Lopes" link: "http://lattes.cnpq.br/8246131317396176" - name: "Gerlimara Paulo de Araujo" link: "http://academic.research.microsoft.com/Author/56818996/ap-de-araujo" - name: "Vania Vieira Estrela" link: "http://academic.research.microsoft.com/Publication/584912/regularized-pel-recursive-motion-estimation-using-generalized-cross-validation-and-spatial" - name: "Vania Vieira Estrela" link: "http://academic.research.microsoft.com/Publication/584912/regularized-pel-recursive-motion-estimation-using-generalized-cross-validation-and-spatial" - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" year: "2005" doi: "10.1117/12.632674" abstract: "The pel-recursive computation of 2-D optical flow has been extensively studied in computer vision to estimate motion from image sequences, but it still raises a wealth of issues, such as the treatment of outliers, motion discontinuities and occlusion. It relies on spatio-temporal brightness variations due to motion. Our proposed adaptive regularized approach deals with these issues within a common framework. It relies on the use of a data-driven technique called Mixed Norm (MN) to estimate the best motion vector for a given pixel. In our model, various types of noise can be handled, representing different sources of error. The motion vector estimation takes into consideration local image properties and it results from the minimization of a mixed norm functional with a regularization parameter depending on the kurtosis.

As a consequence two very important issues arise: the increased availability of new materials and the need for materials with better performance. Polymer blends are polymer systems originated from the physical mixture of two or more polymers and/or copolymers, without a high degree of chemical reactions between them. To be considered a blend, the compounds should have a concentration above 2% in mass of the second component (Hage & Pessan, 2001; Ihm & White, 1996). However, the commercial viability of new polymers has begun to become increasingly difficult, due to several factors. The advantages of polymer blends lie in the ability to combine existing polymers into new compositions obtaining in this way, materials with specific properties. This strategy allows for savings in research and development of new materials with equivalent properties, as well as versatility, simplicity, relatively low cost (Koning et al., 1998) and faster development time of new materials (Silva, 2011). Rossini (2005) mentions that economically and environmentally, a very viable alternative is to replace the recycling of pure polymers by mixtures of discarded materials. Mechanical recycling causes the breakdown of polymer chains, which impairs the properties of polymers. This degradation is directly proportional to the number of cycles of recycling. Therefore, the blend of two or more discarded polymers can be a realistic alternative, since it can result in materials with very interesting properties, at a low cost. Besides its inexpensiveness, this choice is also a smart solution to the reutilization of garbage. Postconsumption package disposal always occurs in a disorderly manner and without regard for the environment. The recycling process becomes increasingly more important and necessary to remediate environmental impact. According Pang et al. (2000) apud Marconcini & Ruvolo Filho (2006) polyolefins such as high density polyethylene (HDPE), low density polyethylene (LDPE) and polypropylene (PP) and polyesters such as poly (ethylene terephthalate) (PET) are classes of thermoplastics that have been widely used in packaging and constitute a large part of post-consumer waste. The recycling of these materials and their mechanical characterization anticipating the possibility of a new cycle of life in the form of new products is challenging, although technologically and environmentally correct (Marconcini & Ruvolo Filho, 2006). The polymer blends can be obtained basically in two ways (Rossini, 2005):  By dissolving the polymers in a good solvent, common to them, and subsequently letting the solvent evaporate; and  In a mixer where the working temperature is high enough to melt or mollify the polymeric components, without causing degradation of the same. According to Wessler (2007), the polymer blends may be miscible or immiscible. The miscibility is the most important property to be analyzed in a blend, given that all other system properties depend on the number of phases, their morphology and adhesion between them. The miscibility term is directly related to the solubility, i.e., a blend is miscible when the polymers dissolve in each other mutually (Silva, 2011). The immiscible between the various engineering polymers is a limiting factor for its production. Thus, it is necessary to use compatibilization agents for their production. Computational modeling has become increasingly popular. The main objective of models is to assist process optimization with minimal investment of time and resources for experimental work. Most techniques are classified into two main groups: physical models and statistical models as shown by Malinov & Sha (2003). Statistical methods are chosen according to research objectives. There are several multivariate analysis methods for purposes quite different from each other. The desired value and quality of one or more product characteristics can be obtained via experiment analysis and DOE. These methods help determining optimal settings and controllable factors of a process such as: temperature, pressure, amount of reagents, operating time, etc.. When compared to the method of trial and error, DOE also allows a reduction of the number of required tests, and savings in time, labor and money. An important application of DOE is the optimization of experimental formulations as, for example, the composition of mixtures. The formulation development is a fundamental part of the food industry, chemicals, plastics, rubber, paints, medicines, and the like. In materials science, it is important to understand the correlation between material processing, microstructure and properties that enable the optimization of process parameters and compositions of materials to achieve the desired combination of properties, according Malinov & Sha (2003). The problem presented here is to determine the fraction of each polymer blend component, and to determine the agent or, in some cases, an agents system, when it is necessary to use more than one compatibilizing agent. Thus, this text studies the effect of factors, for example, amount of polypropylene, additive type, and amount of additive in the composition of polymer blends, i.e., the optimal polymer blends formulation using factorial design." links: "url": "http://www.intechopen.com/books/principal-component-analysis-engineering-applications/methodology-for-optimization-of-polymer-blends-composition" tags: - "control systems" - "design science" - "rule-based" - "Recycling" - "operating system" - "Environmental Engineering " - "composition" - "design research" - "testing" - "type system" - "model-driven development" - "model-driven engineering" - "Engineering Design for Environment" - "Meta-Environment" - "process modeling" - "Sustainability" researchr: "https://researchr.org/publication/coelho2012methodology" cites: 32 citedby: 1 kind: "misc" key: "coelho2012methodology" - title: "Deep Learning for Image Processing Applications" author: - name: "Jude Hemanth" link: "https://scholar.google.com/citations?user=UFnBlEEAAAAJ&hl=en" - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" - name: "Vania Vieira Estrela" link: "http://scholar.google.com/citations?user=-ZbglqgAAAAJ&hl=en" - name: "Vania Vieira Estrela" link: "http://scholar.google.com/citations?user=-ZbglqgAAAAJ&hl=en" - name: "Vania Vieira Estrela" link: "http://scholar.google.com/citations?user=-ZbglqgAAAAJ&hl=en" - name: "Vânia Estrela" link: "http://br.linkedin.com/pub/vania-v-estrela/29/9bb/96b/" - name: "Jude Hemanth" link: "https://scholar.google.com/citations?user=UFnBlEEAAAAJ&hl=en" year: "2017" researchr: "https://researchr.org/publication/hemanth2018deep" cites: 0 citedby: 1 howpublished: "Print and Online" kind: "misc" key: "hemanth2018deep" - title: "HYPERSPECTRAL ANALYSIS OF REMOTELY SENSED IMAGES " author: - name: "F.

Abrupt changes in regular water distribution - such as shortage or inundation - may be catastrophic. To circumvent issues regarding overload and scarcity of water, huge sums of capital have to be invested and knowledge from several areas like hydrology and civil engineering can be applied to manage and allocate water. Since near ¾ of the Earth corresponds to oceans, water scarcity results from poor temporal and spatial water allocation as well as unsatisfactory quality to fulfill local needs. This makes water a restrictive factor for the progress of agriculture and industries. Existing information on water control systems is almost always insufficient leading to some critical situations. These unsatisfactory effects could have been evaded if enough hydrologic, geologic and climatologic data for planning had been readily available. This text aims at showing the relevance of remote sensing (RS) and Geographical Information Systems (GIS) techniques when it comes to acquire hydrologic data and to support operational as well as managerial hydrology.

TLS method solves an inconsistent system Gu=z , with G and z in error due to temporal/spatial derivatives, and nonlinearity, while the Ordinary Least Squares (OLS) model has noise only in z. Sources of difficulty involve the non-stationarity of the field, the ill-posedness, and the existence of noise in the data. Three ways of applying the TLS with different noise conjectures to the end problem are observed. First, the classical TLS (cTLS) is introduced, where the entries of the error matrices of each row of the augmented matrix [G;z] have zero mean and the same standard deviation. Next, the Generalized Total Least Squares (GTLS) is defined to provide a more stable solution, but it still has some problems. The Generalized Scaled TLS (GSTLS) has G and z tainted by different sources of additive zero-mean Gaussian noise and scaling [G;z] by nonsingular D and E, that is, D[G;z]E makes the errors iid with zero mean and a diagonal covariance matrix. The scaling is computed from some knowledge on the error distribution to improve the GTLS estimate. For moderate levels of additive noise, GSTLS outperforms the OLS, and the GTLS approaches. Although any TLS variant requires more computations than the OLS, it is still applicable with proper scaling of the data matrix." researchr: "https://researchr.org/publication/de-JesusEstrelaEstrelaEstrelade-Jesusde-JesusEstrelaEstrela2017" cites: 39 citedby: 2 journal: "Oriental Journal of Computer Science and Technology" volume: "10" number: "3" kind: "article" key: "de-JesusEstrelaEstrelaEstrelade-Jesusde-JesusEstrelaEstrela2017" - title: "Estimating Motion with Principal Component Regression Strategies" author: - name: "Felipe Pereira do Carmo" link: "https://www.linkedin.com/in/felipe-pereira-do-carmo-b452b648/?ppe=1" - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" - name: "Joaquim Teixeira de Assis" link: "http://academic.research.microsoft.com/Author/54447924/j-t-de-assis" - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" - name: "Felipe Pereira do Carmo" link: "https://www.linkedin.com/in/felipe-pereira-do-carmo-b452b648/?ppe=1" - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" - name: "Joaquim Teixeira de Assis" link: "http://academic.research.microsoft.com/Author/54447924/j-t-de-assis" - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" year: "2009" doi: "10.1109/mmsp.2009.5293264" researchr: "https://researchr.org/publication/do-CarmoEstrelade-AssisEstrelaEstrelado-CarmoEstrelade-AssisEstrelaEstrela2009" cites: 0 citedby: 1 kind: "inproceedings" key: "do-CarmoEstrelade-AssisEstrelaEstrelado-CarmoEstrelade-AssisEstrelaEstrela2009" - title: "Emergency Response Cyber-Physical System for Disaster Prevention with Sustainable Electronics" author: - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" - name: "Osamu Saotome" link: "http://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4780730Y6" - name: "Jude Hemanth" link: "https://scholar.google.com/citations?user=UFnBlEEAAAAJ&hl=en" - name: "Rui J.

It is common to establish a priori data to aid the estimation process. One can move some steps forward by means of a deformable model, for example, the snake model. In up to date research, the deformable contour is represented via B-spline snakes, which allows local control, concise depiction, and the use of fewer parameters. The estimation of edges with sub-pixel accuracy via a global B-spline depiction depends on determining the edge according to a Maximum Likelihood (ML) agenda and using the observed information likelihood. This practice guarantees that outliers present in data will be cleaned out. The data likelihood is calculated as a result of the observation model comprising both orientation and position data. Experiments where this procedure and the traditional spline interpolation have revealed that the algorithm introduced outperforms the conventional method for Gaussian as well as Salt and Pepper noise." links: technicalreport: "https://researchr.org/publication/preprint-citeulike%3A14138591" "url": "http://dx.doi.org/10.1109/ist.2014.6958448" tags: - "sub-pixel accuracy" - "Maximum Likelihood Estimation" - "image processing" - "surveillance" - "Remote Sensing" - "multimedia" - "B-spline" researchr: "https://researchr.org/publication/IEEEIST14138591" cites: 30 citedby: 2 pages: "68-72" booktitle: "2014 IEEE International Conference on Imaging Systems and Techniques (IST) Proceedings" kind: "inproceedings" key: "IEEEIST14138591" - title: "Proceedings of the 3rd Brazilian Technology Symposium: Emerging Trends and Challenges in Technology" author: - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" - name: "Vania Vieira Estrela" link: "http://scholar.google.com/citations?user=-ZbglqgAAAAJ&hl=en" - name: "Vania Vieira Estrela" link: "http://scholar.google.com/citations?user=-ZbglqgAAAAJ&hl=en" - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" - name: "Vania Vieira Estrela" link: "http://scholar.google.com/citations?user=-ZbglqgAAAAJ&hl=en" - name: "Hermes Jose Loschi" link: "https://scholar.google.com.br/citations?user=EqKYim8AAAAJ&hl=pt-BR" - name: "Hermes Jose Loschi" link: "https://scholar.google.com.br/citations?user=EqKYim8AAAAJ&hl=pt-BR" - name: "Hermes Jose Loschi" link: "https://scholar.google.com.br/citations?user=EqKYim8AAAAJ&hl=pt-BR" - name: "Yuzo Iano" link: "https://publons.com/researcher/1301911/yuzo-iano/" - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" year: "2019" researchr: "https://researchr.org/publication/estrela2019proceedings" cites: 0 citedby: 0 howpublished: "Print, online" kind: "misc" key: "estrela2019proceedings" - title: "A PRINCIPAL COMPONENT REGRESSION STRATEGY FOR ESTIMATING MOTION" author: - name: "Vania Vieira Estrela" link: "http://academic.research.microsoft.com/Author/3361386/vania-v-estrela" - name: "Marcos Henrique da Silva Bassani" link: "http://academic.research.microsoft.com/Author/42688555/m-h-da-silva-bassani" - name: "Joaquim Teixeira de Assis" link: "http://academic.research.microsoft.com/Author/54447924/j-t-de-assis" - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" - name: "Vania Vieira Estrela" link: "http://academic.research.microsoft.com/Author/3361386/vania-v-estrela" - name: "Vania Estrela" link: "http://www.linkedin.com/profile/view?id=101025443&trk=h-gnav-name-link-0" - name: "Marcos Henrique Da Silva Bassani" link: "http://academic.research.microsoft.com/Author/10661924/marcos-h-s-bassani" - name: "Marcos Henrique da Silva Bassani" link: "http://academic.research.microsoft.com/Author/42688555/m-h-da-silva-bassani" - name: "Vania Vieira Estrela" link: "http://academic.research.microsoft.com/Publication/584912/regularized-pel-recursive-motion-estimation-using-generalized-cross-validation-and-spatial" - name: "M.

This is the case for Unmanned Aerial Vehicles (UAVs) based on open-source hardware (OSH) as well. Open-source software (OSS) and OSH can be applied in a wide range of applications and can improve several technologies. The chapter begins with an introduction to OSS depicting its rationale, description of fundamental differences between OSS and proprietary software (PS), what benefits OSSs provide to overall UAV community, the motives leading people to pick up an OSS instead of a PS, which helps the academic and research community. This chapter also covers some OSSs used within the UAV community to support all aspects of UAV technology and the Remote Sensing (RS) and photogrammetry data post-processing chain. It is possible to build fully autonomous and operational UAV based only on OSH and OSS.

The hierarchically structured bounding boxes help us to quickly isolate the contour of segments in interference. In this paper, a new approach is introduced to treat the interference detection problem involving the representation of arbitrary shaped objects. Our proposed method relies upon searching for the best possible way to represent contours by means of hierarchically structured rectangular oriented bounding boxes. This technique handles 2D objects boundaries defined by closed B-spline curves with roughness details. Each oriented box is adapted and fitted to the segments of the contour using second order statistical indicators from some elements of the segments of the object contour in a multiresolution framework. Our method is efficient and robust when it comes to 2D animations in real time. It can deal with smooth curves and polygonal approximations as well results are present to illustrate the performance of the new method." tags: - "Interference Detection" - " Collision Detection" - "C++" - "Computação gráfica" - " Oriented Box" - "Oriented bounding box" - " Multiresolution Representation" - "systematic-approach" - " Bounding Box" researchr: "https://researchr.org/publication/RiveraEC04" cites: 0 citedby: 5 pages: "219" booktitle: "WSCG (Short Papers)" kind: "inproceedings" key: "RiveraEC04" - title: "HYPERSPECTRAL ANALYSIS OF REMOTELY SENSED IMAGES " author: - name: "F.

Abrupt changes in regular water distribution - such as shortage or inundation - may be catastrophic. To circumvent issues regarding overload and scarcity of water, huge sums of capital have to be invested and knowledge from several areas like hydrology and civil engineering can be applied to manage and allocate water. Since near ¾ of the Earth corresponds to oceans, water scarcity results from poor temporal and spatial water allocation as well as unsatisfactory quality to fulfill local needs. This makes water a restrictive factor for the progress of agriculture and industries. Existing information on water control systems is almost always insufficient leading to some critical situations. These unsatisfactory effects could have been evaded if enough hydrologic, geologic and climatologic data for planning had been readily available. This text aims at showing the relevance of remote sensing (RS) and Geographical Information Systems (GIS) techniques when it comes to acquire hydrologic data and to support operational as well as managerial hydrology. This work shows how image processing can be applied to help hydrology" links: "url": "http://books.google.com.br/books?hl=pt-BR\\&\\#38;lr=\\&\\#38;id=RV-SeH7ilP4C\\&\\#38;oi=fnd\\&\\#38;pg=PA398\\&\\#38;dq=\\%22vania+vieira+estrela\\%22\\&\\#38;ots=rqYtLvTQ1o\\&\\#38;sig=4korIoC4wc1S1byBqBHAdPfkckc" tags: - "control systems" - "data-flow analysis" researchr: "https://researchr.org/publication/da2011hyperspectral" cites: 21 citedby: 4 booktitle: "Sustainable Water Management in the Tropics and Subtropics and Case Studies in Brazil" publisher: "University of Kassel" isbn: "9788563337214" chapter: "HYPERSPECTRAL ANALYSIS OF REMOTELY SENSED IMAGES" kind: "inbook" key: "da2011hyperspectral" - title: "IEEE Access Special Section Editorial: Soft Computing Techniques for Image Analysis in the Medical Industry - Current Trends, Challenges and Solutions" author: - name: "D.

Error concealment intends to improve the effects of disturbances at the reception due to bit-errors or cell loss in packet networks. Bregman regularization gives accurate answers after just some iterations with fast convergence, better accuracy and stability.

They permit reliable and timely delivery of image and video data over the Internet. In block transform coding, the spatial redundancies inside blocks are removed, and the energy is compacted into a small number of coefficients after the transformation. Realistic communication channels are not error free, although the loss mechanism may vary widely from media to media. Data corruption may be caused by network congestion, thermal noise, switch noise, signal fade, bit-errors in noisy channels, cell loss in packet networks, etc.. Since the signals transmitted on real-world channels are highly compressed, independent of cause, the quality of images reconstructed from any corrupted data can be very unsatisfactory. Error concealment is intended to ameliorate the impact of channel impairments by utilizing a priori information about typical images in conjunction with available picture redundancy to provide subjectively acceptable renditions of affected picture regions.

The digital farm project introduces several class activities connected to the protagonist's universe and a real-life rural community. The instructor can handle a multitude of optimization problems learners can relate to and solve them. The class and the instructor can interact with other subjects like programming and application development. In Brazil, this is paramount due to the high levels of anxiety felt by engineering students.

However, developing a new computer vision (CV) software is complicated because many factors influence the extraction of information from aerial images, such as lighting, flight altitude, and optical sensors. The CV has been incorporated in most modern machines such as autonomous vehicles and industrial robots. The aim is to produce a high-quality image database of low-altitude Unmanned Aerial Vehicle (UAV) flights with flight condition-logged for photogrammetry, remote sensing, and CV. This work resulted in a collection of aerial images in the visible and thermal spectrum, and this set of images was captured in different schedules of the day, altitudes of flight, times of the year. The cameras are synchronised with the UAVs autopilot, and they were spatially and spectrally characterised in the laboratory. This research makes available low altitude aerial images of a region in Brazil to all community, with the precise flight and capture information, as well as additional features such as ground truth and georeferenced mosaic. Examples of the use of the database are shown for mosaic generation and development of CV algorithms for autonomous navigation of UAVs [1,2]. Furthermore, this database will serve as a benchmark for the development of the CV algorithms suited for autonomous navigation by images.

Efficient MC is one of the certain reasons for H.264/AVC superior performance compared to its antecedents. The H.264/AVC has selective intra-prediction and optimized inter-prediction methods to reduce temporal and spatial redundancy more efficiently. Motion compensation/prediction using variable block sizes and directional intra-prediction to choose the adequate modes help decide the best coding. Unfortunately, motion treatment is a computationally-demanding component of a video codec.

TLS method solves an inconsistent system Gu=z , with G and z in error due to temporal/spatial derivatives, and nonlinearity, while the Ordinary Least Squares (OLS) model has noise only in z. Sources of difficulty involve the non-stationarity of the field, the ill-posedness, and the existence of noise in the data. Three ways of applying the TLS with different noise conjectures to the end problem are observed. First, the classical TLS (cTLS) is introduced, where the entries of the error matrices of each row of the augmented matrix [G;z] have zero mean and the same standard deviation. Next, the Generalized Total Least Squares (GTLS) is defined to provide a more stable solution, but it still has some problems. The Generalized Scaled TLS (GSTLS) has G and z tainted by different sources of additive zero-mean Gaussian noise and scaling [G;z] by nonsingular D and E, that is, D[G;z]E makes the errors iid with zero mean and a diagonal covariance matrix. The scaling is computed from some knowledge on the error distribution to improve the GTLS estimate. For moderate levels of additive noise, GSTLS outperforms the OLS, and the GTLS approaches. Although any TLS variant requires more computations than the OLS, it is still applicable with proper scaling of the data matrix." researchr: "https://researchr.org/publication/de-JesusEstrelaEstrelaEstrelade-Jesusde-JesusEstrelaEstrela2017" cites: 39 citedby: 2 journal: "Oriental Journal of Computer Science and Technology" volume: "10" number: "3" kind: "article" key: "de-JesusEstrelaEstrelaEstrelade-Jesusde-JesusEstrelaEstrela2017" -

It is common to establish a priori data to aid the estimation process. One can move some steps forward by means of a deformable model, for example, the snake model. In up to date research, the deformable contour is represented via B-spline snakes, which allows local control, concise depiction, and the use of fewer parameters. The estimation of edges with sub-pixel accuracy via a global B-spline depiction depends on determining the edge according to a Maximum Likelihood (ML) agenda and using the observed information likelihood. This practice guarantees that outliers present in data will be cleaned out. The data likelihood is calculated as a result of the observation model comprising both orientation and position data.

However, developing a new computer vision (CV) software is complicated because many factors influence the extraction of information from aerial images, such as lighting, flight altitude, and optical sensors. The CV has been incorporated in most modern machines such as autonomous vehicles and industrial robots. The aim is to produce a high-quality image database of low-altitude Unmanned Aerial Vehicle (UAV) flights with flight condition-logged for photogrammetry, remote sensing, and CV. This work resulted in a collection of aerial images in the visible and thermal spectrum, and this set of images was captured in different schedules of the day, altitudes of flight, times of the year. The cameras are synchronised with the UAVs autopilot, and they were spatially and spectrally characterised in the laboratory. This research makes available low altitude aerial images of a region in Brazil to all community, with the precise flight and capture information, as well as additional features such as ground truth and georeferenced mosaic. Examples of the use of the database are shown for mosaic generation and development of CV algorithms for autonomous navigation of UAVs [1,2]. Furthermore, this database will serve as a benchmark for the development of the CV algorithms suited for autonomous navigation by images.

Efficient MC is one of the certain reasons for H.264/AVC superior performance compared to its antecedents. The H.264/AVC has selective intra-prediction and optimized inter-prediction methods to reduce temporal and spatial redundancy more efficiently. Motion compensation/prediction using variable block sizes and directional intra-prediction to choose the adequate modes help decide the best coding. Unfortunately, motion treatment is a computationally-demanding component of a video codec.

We propose a new approach which allows us to deal with these issues within a common framework. Our approach is based on the use of a technique called Generalized Cross-Validation to estimate the best regularization scheme for a given pixel. In our model, the regularization parameter is a matrix whose entries can account for diverse sources of error. The estimation of the motion vectors takes into consideration local properties of the image following a spatially adaptive approach where each moving pixel is supposed to have its own regularization matrix.

Costuma ser impossível experimentar todas as alternativas de algoritmos e parametrizações. Em geral, para que os técnicos se orientem durante o processo, é necessária a adoção de metodologias que norteiem as ações. No entanto, além de serem poucas as metodologias com esse propósito, em geral não existem mecanismos computacionais que auxiliem o processo de aplicação das metodologias. Assim sendo, o presente artigo tem como objetivo descrever a modelagem de um sistema de informação que viabilize a aplicação da metodologia para realização de KDD proposta. O sistema, já desenvolvido, vem sendo utilizado com sucesso como apoio ao processo de ensino de KDD em disciplinas oferecidas pelos autores tanto em nível de graduação quanto em nível de pós-graduação. Para modelagem foram utilizados recursos da linguagem de modelagem unificada UML. Os modelos de casos de uso e de classes do sistema foram detalhados e comentados. Conclusões e alternativas de melhorias futuras na ferramenta também foram fornecidas.

Objective: Based on this, the present study aims to implement a DES (Discrete Event Simulation) based model. This model is called CBEDE (Coding of Bits for Entities by means of Discrete Events) and aims to assist SUS by categorizing a broad spectrum of health-related topics as well as improving the transmission of medical data. Methodology: DES is an effective tool to approach a wide variety of health care issues. This technique has been used to model concepts with a high-level of abstraction in a system, such as patients, nurses, doctors; can be applied from the exchange of emails on a clinical server to the transmission of data packets between devices connected in a hospital network, which also uses the queuing concept and can be used to manage patient data, medical staff, or same emergency departments, intensive care units, surgical procedures, outpatient clinics, ie, the entire extent of a healthcare system. Aiming to solve such problems, the present study implements a model CBEDE applied to a healthcare system, and advanced modulation format DQPSK in a simulation environment, the Simulink simulation environment of the MATLAB software, improving the transmission of data, through a pre-coding process of bits applying discrete events in the signal before the modulation process. This proposal brings a new approach for signal transmission. In this case, the transmission is performed in the discrete domain with the implementation of discrete entities in the bit generation process. This study aims to increase the information capacity for healthcare systems. Results: Through simulations the model without the proposal consumed 55.5MB which in contrast the proposal had 28.82MB of consumption, in MB (Megabytes). Being the differential of this research the use of discrete events applied in the physical layer of a transmission medium, the bit itself, being this a low-level of abstraction, the results show better computational performance related to memory utilization and to the compression of the information, showing an improvement of 92.6%. Conclusion: Patients awaiting consultation with a medical specialist, in the context of a system interconnected between hospitals (which nowadays this is already reality). However the systems currently used are slow and consume a lot of system memory, facilitating crashes. With exchange patient data and medical consultations with each other, such scheduling of consultations may become more effective. This demonstrates that the CBEDE has great potential in the improvement of the hospital services. This potential of improvement of already existing processes can increase the performance of communication response between all the devices in the hospital system, because the flow of data will consume fewer resources and, therefore, can improve the interactions between doctor and patient.

However, in the presence of noise, it becomes an il-posed problem that requires regulation. In the past, regularization for pel-recursive estimations was addressed in an ad-hoc manner. In this paper, a Bayesian estimation framework is used to deal with this issue. More specifically, motion vectors and regularization parameters are estimated in an iterative fashion by means of the Expectation- Maximization (EM) algorithm and a Gaussian data model. The proposed algorithm utilizes the local image properties to regularize the motion vector estimates following a spatially adaptive approach. Numerical experiments are presented that demonstrate the merits of the proposed algorithm." tags: - "rule-based" - "Expectation-Maximization Algorithm" - "regularization" - "EM Algorithm" - "Inverse problems" - "2D optical flow " - "image processing" - "Computer vision" - "Motion estimation" researchr: "https://researchr.org/publication/EstrelaGalatsanosEstrelaGalatsanos2000" cites: 0 citedby: 6 kind: "inproceedings" key: "EstrelaGalatsanosEstrelaGalatsanos2000" - title: "Open-source software (OSS) and hardware (OSH) in UAVs" author: - name: "Burdziakowski, Pawel" link: "https://researchr.org/alias/burdziakowski%2C-pawel" - name: "Razmjooy, Navid" link: "https://researchr.org/alias/razmjooy%2C-navid" - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" - name: "Hemanth, Jude" link: "https://researchr.org/alias/hemanth%2C-jude" - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" year: "2020" month: "apr" doi: "10.1049/pbce120g_ch3" abstract: "The popularity of the Open Source Tool (OST) has expanded significantly.

Experiments where this procedure and the traditional spline interpolation have revealed that the algorithm introduced outperforms the conventional method for Gaussian as well as Salt and Pepper noise." links: published: "https://researchr.org/publication/IEEEIST14138591" researchr: "https://researchr.org/publication/preprint-citeulike%3A14138591" cites: 27 citedby: 0 type: "Preprint" kind: "techreport" key: "preprint-citeulike:14138591" - title: "HOW TO USE ORCID TO FACILITATE INTELLECTUAL PROPERTY MANAGEMENT" author: - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" - name: "Vania Estrela" link: "http://scholar.google.com/citations?user=-ZbglqgAAAAJ&hl=en" - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" - name: "Vania Vieira Estrela" link: "http://scholar.google.com/citations?user=-ZbglqgAAAAJ&hl=en" - name: "Vania Estrela" link: "http://scholar.google.com/citations?user=-ZbglqgAAAAJ&hl=en" - name: "Vania Vieira Estrela" link: "http://scholar.google.com/citations?user=-ZbglqgAAAAJ&hl=en" - name: "Vania Vieira Estrela" link: "http://scholar.google.com/citations?user=-ZbglqgAAAAJ&hl=en" - name: "Osamu Saotome" link: "http://academic.research.microsoft.com/Author/3476641/osamu-saotome?query=osamu%20saotome" - name: "Osamu Saotome" link: "http://academic.research.microsoft.com/Author/3476641/osamu-saotome?query=osamu%20saotome" - name: "others" link: "https://researchr.org/alias/others" year: "2017" researchr: "https://researchr.org/publication/estrela2017use" cites: 0 citedby: 0 howpublished: "Online" kind: "misc" key: "estrela2017use" - title: "Data-Driven Motion Estimation with Spatial Adaptation" author: - name: "Alessandra Martins Coelho" link: "http://academic.research.microsoft.com/Author/53930956/alessandra-martins-coelho" - name: "Vania Vieira Estrela" link: "http://academic.research.microsoft.com/Author/3361386/vania-v-estrela" - name: "Vania Vieira Estrela" link: "http://academic.research.microsoft.com/Author/3361386/vania-v-estrela" - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" - name: "Alessandra Martins Coelho" link: "http://academic.research.microsoft.com/Author/53930956/alessandra-martins-coelho" - name: "Alessandra Martins Coelho" link: "http://academic.research.microsoft.com/Author/53930956/alessandra-martins-coelho" - name: "Vânia Vieira Estrela" link: "http://scholar.google.com/citations?hl=en&user=-ZbglqgAAAAJ&view_op=list_works&pagesize=100" - name: "Vânia Estrela" link: "http://br.linkedin.com/pub/vania-v-estrela/29/9bb/96b/" - name: "Vânia Estrela" link: "http://researchr.org/alias/v%C3%A2nia-vieira-estrela" - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" - name: "Vania Vieira Estrela" link: "http://academic.research.microsoft.com/Author/3361386/vania-v-estrela" - name: "Alessandra Martins Coelho" link: "http://academic.research.microsoft.com/Author/53930956/alessandra-martins-coelho" - name: "Alessandra Martins Coelho" link: "http://academic.research.microsoft.com/Author/53930956/alessandra-martins-coelho" - name: "Vania Vieira Estrela" link: "http://www.linkedin.com/profile/view?id=101025443&trk=h-gnav-name-link-0" - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" - name: "Vania Vieira Estrela" link: "http://www.linkedin.com/profile/view?id=101025443&trk=h-gnav-name-link-0" year: "2012" abstract: "Besides being an ill-posed problem, the pel-recursive computation of 2-D optical flow raises a wealth of issues, such as the treatment of outliers, motion discontinuities and occlusion. Our proposed approach deals with these issues within a common framework. It relies on the use of a data-driven technique called Generalized Cross Validation (GCV) to estimate the best regularization scheme for a given moving pixel. In our model, a regularization matrix carries information about different sources of error in its entries and motion vector estimation takes into consideration local image properties following a spatially adaptive.

TLS method solves an inconsistent system Gu=z , with G and z in error due to temporal/spatial derivatives, and nonlinearity, while the Ordinary Least Squares (OLS) model has noise only in z. Sources of difficulty involve the non-stationarity of the field, the ill-posedness, and the existence of noise in the data. Three ways of applying the TLS with different noise conjectures to the end problem are observed. First, the classical TLS (cTLS) is introduced, where the entries of the error matrices of each row of the augmented matrix [G;z] have zero mean and the same standard deviation. Next, the Generalized Total Least Squares (GTLS) is defined to provide a more stable solution, but it still has some problems. The Generalized Scaled TLS (GSTLS) has G and z tainted by different sources of additive zero-mean Gaussian noise and scaling [G;z] by nonsingular D and E, that is, D[G;z]E makes the errors iid with zero mean and a diagonal covariance matrix. The scaling is computed from some knowledge on the error distribution to improve the GTLS estimate. For moderate levels of additive noise, GSTLS outperforms the OLS, and the GTLS approaches. Although any TLS variant requires more computations than the OLS, it is still applicable with proper scaling of the data matrix." researchr: "https://researchr.org/publication/de-JesusEstrelaEstrelaEstrelade-Jesusde-JesusEstrelaEstrela2017" cites: 39 citedby: 2 journal: "Oriental Journal of Computer Science and Technology" volume: "10" number: "3" kind: "article" key: "de-JesusEstrelaEstrelaEstrelade-Jesusde-JesusEstrelaEstrela2017" - title: "Error concealment by means of motion refinement and regularized bregman divergence" author: - name: "Alessandra Martins Coelho" link: "http://academic.research.microsoft.com/Author/53930956/alessandra-martins-coelho" - name: "Vania Vieira Estrela" link: "http://academic.research.microsoft.com/Author/3361386/vania-v-estrela" - name: "Felipe Pereira do Carmo" link: "http://academic.research.microsoft.com/Author/49826901/f-p-do-carmo" - name: "Sandro Roberto Fernandes" link: "http://academic.research.microsoft.com/Author/53603335/sandro-r-fernandes" - name: "Vania Vieira Estrela" link: "http://academic.research.microsoft.com/Publication/584912/regularized-pel-recursive-motion-estimation-using-generalized-cross-validation-and-spatial" - name: "Vania Vieira Estrela" link: "http://academic.research.microsoft.com/Publication/584912/regularized-pel-recursive-motion-estimation-using-generalized-cross-validation-and-spatial" - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" - name: "Alessandra Martins Coelho" link: "http://academic.research.microsoft.com/Author/53930956/alessandra-martins-coelho" - name: "Sandro Roberto Fernandes" link: "http://academic.research.microsoft.com/Author/53603335/sandro-r-fernandes" - name: "Alessandra Martins Coelho" link: "http://academic.research.microsoft.com/Author/53930956/alessandra-martins-coelho" - name: "Sandro Roberto Fernandes" link: "http://academic.research.microsoft.com/Author/53603335/sandro-r-fernandes" - name: "Alessandra Martins Coelho" link: "http://academic.research.microsoft.com/Author/53930956/alessandra-martins-coelho" - name: "Alessandra Martins Coelho" link: "http://academic.research.microsoft.com/Author/53930956/alessandra-martins-coelho" - name: "Vânia Estrela" link: "http://br.linkedin.com/pub/vania-v-estrela/29/9bb/96b/" - name: "Vânia Vieira Estrela" link: "http://scholar.google.com/citations?hl=en&user=-ZbglqgAAAAJ&view_op=list_works&pagesize=100" - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" year: "2012" doi: "10.1007/978-3-642-32639-4_78" abstract: "This work addresses the problem of error concealment in video transmission systems over noisy channels employing Bregman divergences along with regularization.

It is common to establish a priori data to aid the estimation process. One can move some steps forward by means of a deformable model, for example, the snake model. In up to date research, the deformable contour is represented via B-spline snakes, which allows local control, concise depiction, and the use of fewer parameters. The estimation of edges with sub-pixel accuracy via a global B-spline depiction depends on determining the edge according to a Maximum Likelihood (ML) agenda and using the observed information likelihood. This practice guarantees that outliers present in data will be cleaned out. The data likelihood is calculated as a result of the observation model comprising both orientation and position data. Experiments where this procedure and the traditional spline interpolation have revealed that the algorithm introduced outperforms the conventional method for Gaussian as well as Salt and Pepper noise." links: technicalreport: "https://researchr.org/publication/preprint-citeulike%3A14138591" "url": "http://dx.doi.org/10.1109/ist.2014.6958448" tags: - "sub-pixel accuracy" - "Maximum Likelihood Estimation" - "image processing" - "surveillance" - "Remote Sensing" - "multimedia" - "B-spline" researchr: "https://researchr.org/publication/IEEEIST14138591" cites: 30 citedby: 2 pages: "68-72" booktitle: "2014 IEEE International Conference on Imaging Systems and Techniques (IST) Proceedings" kind: "inproceedings" key: "IEEEIST14138591" - title: "Estimating motion with principal component regression strategies" author: - name: "Felipe Pereira do Carmo" link: "http://lattes.cnpq.br/2437533314886489" - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" - name: "Joaquim Teixeira de Assis" link: "http://lattes.cnpq.br/7307238902576135" - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" - name: "Vania Vieira Estrela" link: "https://www.researchgate.net/profile/Vania_Estrela?ev=hdr_xprf&_sg=l2it7UJUf2g4wSUGGVaee_gK6wbXK75hN_Rt6P_99NMr2_HObKqAkOwo4ujJMZp7" - name: "V V Estrela" link: "http://researchr.org/alias/estrela%2C-vania-vieira" - name: "V.

This technique has an adaptive nature: the regularization functional is updated according to Bregman functions that change from iteration to iteration according to the nature of the neighborhood under study at iteration n.

Anything but reduced human monitoring became impossible by means of its physical and economic implications, and an advance towards an automated surveillance becomes the only way out. When it comes to a computer vision system, automatic video event comprehension is a challenging task due to motion clutter, event understanding under complex scenes, multi-level semantic event inference, contextualization of events and views obtained from multiple cameras, unevenness of motion scales, shape changes, occlusions and object interactions among lots of other impairments. In recent years, state-of-the-art models for video event classification and recognition include modeling events to discern context, detecting incidents with only one camera, low-level feature extraction and description, high-level semantic event classification and recognition. Even so, it is still very burdensome to recuperate or label a specific video part relying solely on its content. Principal component analysis (PCA) has been widely known and used, but when combined with other techniques such as the expectation-maximization (EM) algorithm its computation becomes more efficient. This chapter introduces advances associated to the concept of Probabilistic PCA (PPCA) analysis [Tipping et al., 1999)] by of video event understanding technologies. The PPCA model-based method results from the combination of a linear model and the EM algorithm in an iterative fashion in order to determine a principal subspace (PS). Thus, additional work may be needed to find precise principal eigenvectors of the data covariance matrix, with no rotational uncertainty. Kernel principal component analysis (KPCA) is a nonlinear PCA extension that relies on the kernel trick. It has received immense consideration for its value in nonlinear feature mining and other applications. On the other hand, the main drawback of the standard KPCA is that the huge amount of computation required, and the space needed to store the kernel matrix. KPCA can be viewed as a primal space problem with samples created via incomplete Cholesky decomposition. Therefore, all the efficient PCA algorithms can be easily adapted into KPCA. Furthermore, KPCA can be extended to a mixture of local KPCA models by applying the mixture model to probabilistic PCA in the primal space. The theoretical analysis and experiments can shed light onthe performance of the proposed methods in terms of computational efficiency and storage space, as well as recognition rate, especially when the number of data points n is large. By considering KPCA from a probabilistic point of view with the help of the EM algorithm, the computational load can be alleviated, but there still exists a rotational ambiguity with the resulting algorithm implementation. To unravel this intricacy, a constrained EM algorithm for KPCA (and PCA) was formulated founded on a coupled probability model. This brings in advantages related to many factors such as the necessary precision of extracted components, the number of the separated smaller data sets (which is usually empirically set), and the data to be processed. As a generic methodology, another thread of speeding up kernel machine learning is to seek a low-rank approximation to the kernel matrix. Since, as noted by several researchers, the spectrum of the kernel matrix tends to decay rapidly, the low-rank approximation often achieves satisfactory precision. This chapter also aims at looking closely to ways and metrics in order to evaluate these less intensive EM implementations of PCA and KPCA.
