Aiming at H.263 coder,studying some optimization techniques for improving the efficiency of motion estimation algorithm in software implementation,a succinct and efficient method based on bit sign is proposed to avoid repetition of search point.Setting the search order of points in one template based on motion vector's unequal distribution in each direction,and comparing the performance of H.263 coder before and after above-mentioned optimization.The whole pixel and half pixel search points of reconstructed image are reduced,the compressed time of the average per frame is shortened greatly,and the code length of the average per frame is shortened.
