ABSTRACT:
Representative points vicinal to a detected contour line of an image-segmented input picture are corrected in position so that lattice links connecting the representative points extend along the detected contour line, and motion vectors are detected at the corrected representative points, before a motion vector at each pixel in the picture is interpolated from the detected motion vectors at representative points near thereto, for a motion-compensated inter-frame prediction small of a deformed distortion.
