Abstract :
The advanced video coding (AVC) standard H.264 achieves better video compression performance compared with the previous standards and one of major feature is search algorithm. In block-matching motion estimation, the search pattern with different shape and different size can impact the search performance very much. Based on the distribution of motion vector and diamond search algorithm, a newly developed diamond search algorithm is proposed in this paper. Simulation results demonstrate that the proposed algorithm outperforms other well-known fast block matching algorithm greatly. And the performance is also better than diamond search algorithm.
