Abstract
The emerging High Efficiency Video Coding (HEVC) standard is a new improved next generation video coding standard. HEVC aims to provide improved compression performance as compared to all other video coding standards. To improve the coding efficiency a number of new techniques have been used. The higher compression efficiency is obtained at the cost of an increase in the computational load. In HEVC 35 modes are provided for intra prediction to improve the compression efficiency. The best mode is selected by Rate Distortion Optimization (RDO) process. It achieves significant improvement in coding efficiency compared with previous standards. However, this causes high encoding complexity. This paper discuss the various fast mode decision algorithms for intra prediction in HEVC.
高效视频编码(High Efficiency Video Coding, HEVC)标准是新一代视频编码标准的改进。与所有其他视频编码标准相比，HEVC旨在提供更好的压缩性能。为了提高编码效率，采用了许多新技术。压缩效率的提高是以计算量的增加为代价的。在HEVC中，为了提高压缩效率，提供了35种模式用于帧内预测。通过速率失真优化(RDO)过程选择最佳模式。与以前的标准相比，它在编码效率上有了很大的提高。然而，这会导致较高的编码复杂度。讨论了HEVC中用于帧内预测的各种快速模式决策算法。
