| 中文摘要: |
| 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. |
| 英文摘要: |
| 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-pixel 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. |
