The authors present an efficient search technique which minimized the computations necessary for estimating the motion in video sequences by the block matching method. They also discuss the theoretical basis for conducting such a reduced search by this technique. They present two algorithms that use the proposed technique for estimating the motion typical of a video-conferencing environment. Next, the results of computer simulations on a real video sequence that demonstrate the effectiveness of the proposed technique are given. Finally, the results of a study of statistical properties of block motion-compensated frame difference signals are also summarized.
