Optimization of UMHexagonS on block matching motion estimation algorithms in H.264
Zhou Chengwu · Computer Engineering and Applications Journal · 2011
Block matching motion estimation is one of the core-technique of video coding.Research on efficient and fast video compression coding technology has already been a hot topic for technician and researchers all over the world.Based on the analysis of UMHexagons algorithm adopted by video compression H.264 the coding standard,the termination search and search template have been optimized respectively,which reduces the search points effectively,and increases the efficiency of motion estimation algorithm.The experiments on four typical video sequences prove that,compared to the original algorithm,the motion estimation time can be saved 11.75% on average by the optimized algorithm,and the real-time performance of the video compression has been enhanced under almost the same circumstance of picture quality.
