AVS视频编码中分像素插值的SSE2优化方法

Sub-pixel Interpolation Optimization by SSE2 in AVS Video Coding

视频编码中分像素插值是运动补偿中比较复杂的算法,耗时较长。利用SSE2指令系统并行处理的特性,针对AVS视频编码的分像素插值部分提出一种优化算法。实验结果表明,该算法可使该模块的平均执行时间缩短为原来的1/3。

The sub-pixel interpolation is a complex algorithm in motion compensation of Video Coding. Base on the SSE2 characterize, a sub-pixel interpolation algorithms for an AVS codec is designed to optimize the program. Experiments show that the algorithm can reduce the execution time to 1/3 of original.
