| 摘 要： | 简要介绍了AVS标准的发展和现状，对其运动估计算法的技术特点与流程进行了详细分析，并与H．264的相应技术做了比较。针对原算法，在子象素运动估计上做了改进与优化，提出了一种新的基于整象素SAD的快速子象素运动估计算法。经验证该方法在基本保持性能的前提下，较大程度地降低了运动估计算法的复杂度。

| Abstract: | The development and status of AVS firstly were introduced bridfly. Then it gives a detailed analysis of the technical features and the flow of motion estimation algorithm in AVS are given and compared with the relevant parts of H. 264. The improrement and optimization of sub - pixcl motion estimation algorithm were made. Anew fast motion estimation algorithm was proposed, which is based on SAD of integer - pixel. The experiment results indicate that it can reduce the complexity of motion estimation but maintain the performance. |
