H.264/AVC video coding standard introduces motion estimation with multiple block sizes to achieve a considerably higher coding efficiency.The improved small diamond search algorithm based on the motion vector is proposed.According to the direction of the prediction motion vector in the motion estimation process,the use of different search direction diamond model can be used a shorter period of time to find the best matching block,while greatly reducing the number of search points,to improve the search speed.Compared with several other typical diamond search method,the method improve the coding rate about 5.36% with similar image quality.
