Analysis and Optimization of Motion Estimation Algorithm: UMHexagonS
Yong Li · Journal of Hangzhou Dianzi University · 2013
As one of the key techniques in the new video compression codec standards,motion estimation has become the concentration because of its tremendous computing workload. This paper proposes two aspects optimizations on the basis of the study of UMHexagonS,which include search pattern based on motion vector distribution and spiral subset matching strategy,and then integrates them into the reference model of H. 264 named JM10. 1. Experiment results show that the optimized UMHexagonS has encoding time and motion estimation reduced 10. 683% and 16. 240% on the condition of almost same video quality and transmission bit rate.
