H.264 employed inter Prediction technique in time domain to enhance coding efficiency,To reduce the complexity of the H.264 encoder,a fast inter prediction algorithm is proposed in this paper.It acts as follows:in the process of inter block partition mode decision,based on the computed results of part partition modes,the probable mode group is decided,from which the best partition mode is selected.And in the process of motion estimation of the partition block,according to the search result of some local positions,the most probable motion area of the searching block is early identified,and then some special search masks are applied accordingly.The experimental results show that,compared with the fast algorithms in the JM reference software,the proposed algorithm can maintain high PSNR and enhance encoding speed obviously.
