Abstract

This special issue of the journal Information Fusion consists of a few selected, substantially extended, and thoroughly revised papers from among the many that were originally presented at FUSION 2004, the Seventh International Conference on Information Fusion held 28 June–1 July 2004 in Stockholm, Sweden (http://www.fusion2004.org). This series of conferences was started in 1998, almost coincident with the founding of their sponsoring professional society, the International Society of Information Fusion (http://www.isif.org). The FUSION 2004 conference received 279 original submissions. Each submission was reviewed by at least three reviewers and 171 papers were accepted for the conference. From a set of the highest ranked papers that came out of the conference review process, the guest editors selected those papers they found most interesting and innovative and invited their authors to submit an extended version for regular review with the journal. Each article was reviewed by three reviewers according to the journal’s standards. Based on this rigorous journal peer-review process, all the papers were further revised to satisfactorily address the reviewer comments. One of the papers is co-authored by the guest editors and was handled by the Editor-in-Chief. Eventually, thirteen papers were accepted for this special issue.
