%X In the process of motion estimation for very low bit rate video coding , a macroblock is partitioned adaptively with a pattern which matches the shape of edges of the objects in the macroblock , and two time differential reference frames are used . To speed up the process of motion estimation , the macroblocks which need not to be coded are distinguished before the process , and a fast search algorithm is used during the process . Simulation results demonstrate that , compared with the advanced prediction mode in H.263 , the proposed method for motion compensation makes higher signal noise ratio (SNR) for the reconstructed image.
