Improved UMHexagonS Motion Estimation Algorithm Based on Sub-Regional Searching
基于子区域最佳运动矢量搜索的UMHexagonS改进算法

H.264/MPEG-4 AVC is the coding standard jointly developed by the Video Coding Experts Group(VCEG) of ITU-T and Moving Picture Experts Group(MPEG) of ISO/IEC.Motion estimation is one of the most time-consuming in H.264/MPEG-4 AVC.In this paper,some of the classic motion estimation algorithms are first analyzed,and then motion vector distribution characteristics is discussed,and a sub-regional UMHexagonS motion estimation Algorithm is proposed.In this algorithm,searching area is divided into nine sub-regions,...
