| 摘 要： | AVS是我国具备自主知识产权的第二代信源编码标准.在它的视频编码中采用了1/2像素或者1/4像素的运动估计,这样就能提高运动矢量位移的精度,使得帧间剩余误差变小,压缩比就能提高.本文在介绍AVS中的分像素插值原理的基础上,给出了一种在实际应用中可行的算法.

| Abstract: | AVS standard is the second general digital audio- video source coding standard which is establishing independently in China. Motion estimation and compensation with half - pixel and a quarter of pixel accuracy is supported by AVS video standard, which can improve the accuracy of motion vector. It should be possible to reduce the intra residual error and improve compression performance. This paper introduces the sub-pixel interpolation theory of AVS and gives a feasible algorithm in practical application. |
