摘要/Abstract

摘要：

提出一种新颖的帧内预测方法．比较每种预测模式的预测块与直流(DC)预测模式的预测块之间的绝对差和．进而判断当前块在各种预测模式下的预测块是否相似．若当前块的各种预测块都相似，则将所有预测块的均值作为当前块的最终预测结果，且不必编码预测模式．实验结果表明，提出的方法较H.264/AVC能够获得更高的编码性能，在恢复视频客观质量PSNR相同时，码率平均下降2.40％，编码时间平均减少25.83％．

关键词: 帧内预测, 模式信息, H.264/AVC, 视频编码

Abstract:

A new intra prediction method is proposed for H.264/AVC intra frame coding. The sum of absolute differences (SAD) between each predicted block and the DC predicted block is used to determine whether those predicted blocks are similar. The average of those predicted blocks is used as the final predicted result if the predicted blocks are similar, and it is useless to encode the prediction mode. Experimental results demonstrate that compared with H.264/AVC, the bit rate can be reduced 2.40％ on average, while the PSNRs of reconstructed videos are the same. At the same time, the encoding time is reduced by 25.83％ on average.

Key words: intra prediction, mode information, H.264/AVC, video coding
