Multiple Rigid Motions: Correspondence and Segmentation

Abstract

Motion has been one of the main research topics in computer vision [96]. Traditionally, people have divided the motion problem into correspondence and structure-from-motion [164]. Actually, however, there is another problem, that is, segmentation of motion images into different rigid objects. Segmentation is very important itself, because in many real world tasks like target following segmentation is a precondition, perhaps more frequently required than accurate shape recovery. Also, from a computational point of view, it has to be solved in the case of multiple motions for both correct correspondence and structure-from-motion computation.
