Abstract:  Because the algorithm of H.264 video codec standard has high complexity, it can not meet the requirement of the video surveillance and wireless transmission which require high compression ratio, low bit-rate and real-time application. This paper, according to ARPS algorithm which has the advantages of the initial point and the adaptive arm length search strategy, uses variable threshold for early termination of policies and template simple search algorithm. Experimental results show that the algorithm is effective in reducing the number of search points, does not have a greater impact on image quality, improves the motion estimation algorithm search rate and robustness.
