中文摘要：

为了降低H.264编码器的计算复杂度,提出了一种快速帧内预测模式选择算法,通过分析帧内预测模式在时间和空间上的相关性,将已编码帧中宏块的帧内预测模式作为当前宏块的候选预测模式,减少了计算的开销。实验结果表明,在图像性能和码率变化不大的情况下,编码时间减少约10%,有利于实时编码的实现。

英文摘要：

In order to reduce the computational complexity,this paper proposed a fast algorithm for the intra-prediction mode selection.By analyzing the spatial correlation and temporal correlation of intra-frame prediction mode,the algorithm used intra-frame prediction modes of macro-blocks in coded frames as the candidate modes of current macro-block,which reduced the cost of computation.Experimental results show that the coding time reduces about 10% without obvious PSNR change.
