Abstract :
A new computational approach is presented for the estimation of displacement fields along contours of moving regions in image sequences. The proposed scheme uses frame differences to determine moving edges, which are then expressed as straight line tokens. Finally, an edge propagation algorithm is used to determine the distance between these moving edge tokens and the frame difference region boundaries to approximate the displacement fields. The performance of the system is evaluated with a real video image sequence
