Abstract

This paper presents an improved algorithm for motion compensated image coding. The algorithm can be appied to videophone or video-conferencing. Background detection is used to reduce the bit rate by eliminating the motion information of the block. For a better estimation the object motion some of the blocks which include edge information are divided further into several subblocks according to the edge components. The algorithm shows the improvement of signal -to-noise ratio in the range of 1. 57-5. 57 dB compared to the other existing algorithms. The algorithm also shows the stable behavior for the abrupt movement as a result of the explicit usage of the edge information in the motion estimation.
