Abstract

The present invention is directed to an apparatus for motion segmentation in the field of motion detection, whereby an initial motion map is processed to a more accurate final motion map which identifies the non- and the movement of pixels between at least two successive images, said apparatus comprising a processing-segmentation device and a combination-logic device. In this apparatus the initial motion map is processed to three different feature maps, describing static edges, moving edges and moving flat areas between at least two successive images, respectively. The present invention is further directed to a corresponding method adapted for motion segmentation in the field of motion detection.
