Motion of edges and motion estimation in a sequence of T.V. pictures

We present in this paper an algorithm for motion estimation pel by pel in a sequence of television pictures. This estimator which will be used for a motion compensated coding, must be fitted any type of scene or motion. Techniques we used, are adaptative algorithm with detectors of ruptures without delays. Hence we estimate an a priori motion information on spatial edges where are chiefly located the abrupt changes in motion.
