Image and Signal Processing

ICISP 2010, the International Conference on Image and Signal Processing, was the fourth ICISP conference, and was held in Trois-Rivi` eres, Qü ebec, Canada. Historically, ICISP is a conference resulting from the actions of researchers of Canada,FranceandMorocco.PreviouseditionsofICISPwereheldinCherbourg- Octeville (France), Agadir (Morocco), and Agadir (Morocco) in 2008, 2003 and 2001, respectively. ICISP 2010 was sponsored by EURASIP (European Assoc- tion for Image and Signal Processing) and IAPR (International Association for Pattern Recognition). The response to the call for papers for ICISP 2010 was encouraging. From 165 full papers submitted, 69 were ?nally accepted (54 oral presentations, and 15 posters). The review process was carried out by the Program Committee members; all are experts in various image and signal processing areas. Each paper was reviewed by atleast two reviewers,and also checkedby the conference Co-chairs. The quality of the papers in these proceedings is attributed ?rst to the authors, and second to the quality of the reviews provided by the experts. We would like to thank the authors for responding to our call, and we thank the reviewers for their excellent work. We wereverypleasedto be ableto include inthe conferenceprogramkeynote talks by three world-renowned experts: Yann Lecun, Silver Professor of C- puter Science and Neural Science, The Courant Institute of Mathematical S- ences and Center for Neural Science, New York University (USA); Theo Gevers, Associate Professor, Faculty of Science, University of Amsterdam (The Neth- lands);andLeoGrady,SeniorMemberofTechnicalSta?withSiemensCorporate Research in Princeton, New Jersey (USA).
