This paper presents an efficient search algorithm utilizes the relationship between local motion similarity and the variation degree of motion vector. The main feature of proposed algorithm are: the motion vectors are classified as the unchanged, the slightly changed and the greatly changed motion vector according to corresponding local motion similarity; then different search schemes are adopted for different kind motion vectors. The experimental results show the proposed algorithm has a significant computational speedup compared with other popular fast algorithms, but offers a similar, even better performance.
