摘要

在本文中，我们首先引入了SKIP模式的早期决策。然后，比较了H.264和AVS-M的快速模内决策。对于H.264，通过利用边缘方向直方图，MB中参与RDO计算的亮度和色度块的模式组合数量已经从592个显著减少到132个。对于AVS-M，我们基于Most_Probable_Mode得到了最佳模式的统计排序表。通过使用这个列表，我们得到一个顺序来评估一个模式是否是最佳模式。实验结果表明，这些方法在不影响编码PSNR和比特率效率的前提下，加快了编码速度。

A comparative study of H.264 and AVS-M fast intra mode decision

In this paper, we first introduced SKIP mode decision at early stage. And then, compared the H.264 and AVS-M fast intra mode decision. For H.264, by making use of the edge direction histogram, the number of mode combinations for luma and chroma blocks in a MB that take part in RDO calculation has been reduced significantly from 592 to as low as 132. For AVS-M, we got a statistical order list of the best mode based on the Most_Probable_Mode. By using this list, we get an order to evaluate if a mode is the best mode or not. Experimental results show that these methods speed up the encoding process without loss of coding PSNR and bitrate efficiency.
