| 摘 要： | 运动估计是H.264中关键技术之一。全搜索(FS)虽然能得到最佳的匹配,但在计算上却很繁琐,难以达到实时的要求。对EPZS、UMHexagonS和简化UMHS快速运动估计算法进行了分析。通过与FS的实验比较,归纳出EPZS、UMHexagonS和简化UMHS算法各自的优势。

| Abstract: | The motion estimation is one of the key technologies in H.264,it is also the most time-consuming part.Full search can obtain the best match,but it can't support the demand of real time due to its complexity of computation.In this paper,we analyze EPZS,UMHexagonS and simplified UMHexagonS algorithms and then give the advantages of these algorithms comparing with FS.The experiment shows that the EPZS,UMHexagonS and simplified UMHexagonS algorithms not only reduce the motion estimation time greatly,but also get good pictures,so they have good application prospect. |
