Research on H.264 Motion Estimation Algorithm Optimization in Real-time Video

摘要：

Because of the requirements of high precision and low encoding complexity, H.264 video coding standard used UMHexagonS algorithm as a viable implementation plan for Block Motion Estimation. This paper has made the improvement to the UMHexagonS algorithm, reflected in two aspects: In the search process of this algorithm has added the adaptive threshold value and played a role ahead of deadline in the search process, saving the search time; Its has turned into five steps search and increase the step rectangle search, reducing the search time. The experimental results show that the proposed method can not only guarantee the coding effect of UMHexagonS algorithm, improve the speed of motion estimation, but also saving the coding time, and improve the overall coding rate.
