Extracting nonrigid moving objects by temporal edges

Describes a method for extracting nonrigid moving objects. Every moving object may be approximated by a set of iso-intensity patches. The method finds the motions of these patches by integrating the locations and the intensities of temporal edges. Then, it finds the objects by finding clusters among the motions of the patches. The proposed method can extract many nonrigid objects on a complicated background. The performance of the proposed method was tested successfully on extracting pedestrians from a cinematic sequence viewing a street crossing
