| 摘 要： | 为优化AVS视频编码算法提高其算法的运算效率,对AVS视频编解码标准中的帧内编码算法结构进行了合理调整,并对AVS帧内预测的C代码进行优化处理,减少了AVS帧内预测算法的冗余计算和判断,实现了一种改进的帧内预测程序.实验结果表明：优化后的AVS视频编码算法的运算速度提高10%以上,编解码的帧率平均每秒提高7帧左右.

| Abstract: | In order to further optimize video-audio coding standard of AVS and improve its computing efficiency,the original algorithm is enhanced by adjusting intra-frame coding structure and optimizing C code of intra-frame prediction.In so doing,the redundant computing and estimating of intra-frame process are reduced,achieving the more efficient intra-frame prediction algorithm.Compared with the generic algorithm,the test results show that the improved algorithm can increase the computing speed by over 10%,and the... |
