Abstract
An apparatus and method for detection of moving objects in a sequence of frames, includes circuitry, a memory, and an image-capture device. The circuitry derives a first optical flow map based on motion information of a first frame and a second frame of a plurality of frames. A second optical flow map is further derived, based on motion information of the second frame and a third frame of the plurality of frames. A first foreground region is further identified that corresponds to the moving objects across the first frame and the second frame and the identified first foreground region is warped across the first frame and the second frame and the moving objects are detected, based on combination of a plurality of pixels in the warped first foreground region and the second foreground region.
