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. Preliminary experiments indicate that this approach provides robust estimates of the optical flow." links: "url": "http://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.224.9608" tags: - " spatial adaptation" - "data validation" - "video processing" - " image motion estimation " - "meta-model" - "regularization" - "2D optical flow " - "image processing" - "Motion estimation" - " generalized cross-validation technique " - "information models" - " occlusion " - "Meta-Environment" - " regularization matrix " - " regularized pel-recursive algorithms " - "systematic-approach" researchr: "https://researchr.org/publication/citeulike%3A11966066" cites: 17 citedby: 7 pages: "54-67" booktitle: "INTERNATIONAL JOURNAL OF IMAGE PROCESSING (IJIP)" kind: "inproceedings" key: "citeulike:11966066"
