The key point of our approach is to consider perceptual grouping as a problem of optimization.<br \/>\nFirst the quality of a grouping is defined with a class of functions inspired by the energy functions used for active contours optimization (involving curvature, co-circularity, grey levels, and orientation). Such functions can be computed recursively, and optimized from a local to a global level with an algorithm related to dynamic programming.<br \/>\nThis is followed by a selection procedure which rates and extracts principal groupings. The validity of our approach is presented with synthetic images, aerial and medical data.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>13th Int&#8217;l Conference on Pattern Recognition ICPR 96, Technical University of Vienna , Austria, (August 25 &#8211; 30, 1996) session A82.3 Citeseer search PDF<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[6,1],"tags":[14,23,26,35],"class_list":["post-9","post","type-post","status-publish","format-standard","hentry","category-04-publications","category-uncategorized","tag-dynamic-programming","tag-non-convex-objects-extraction","tag-perceptual-organization","tag-segmentation","xfolkentry","clearfix"],"_links":{"self":[{"href":"http:\/\/www.alquier.org\/laurent\/sites\/cv\/wp-json\/wp\/v2\/posts\/9","targetHints":{"allow":["GET"]}}],"collection":[{"href":"http:\/\/www.alquier.org\/laurent\/sites\/cv\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"http:\/\/www.alquier.org\/laurent\/sites\/cv\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"http:\/\/www.alquier.org\/laurent\/sites\/cv\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"http:\/\/www.alquier.org\/laurent\/sites\/cv\/wp-json\/wp\/v2\/comments?post=9"}],"version-history":[{"count":0,"href":"http:\/\/www.alquier.org\/laurent\/sites\/cv\/wp-json\/wp\/v2\/posts\/9\/revisions"}],"wp:attachment":[{"href":"http:\/\/www.alquier.org\/laurent\/sites\/cv\/wp-json\/wp\/v2\/media?parent=9"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/www.alquier.org\/laurent\/sites\/cv\/wp-json\/wp\/v2\/categories?post=9"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/www.alquier.org\/laurent\/sites\/cv\/wp-json\/wp\/v2\/tags?post=9"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
