H.264帧内预测模式快速选择算法研究

Fast H.264 Intra-Prediction Mode Selection

本文提出了一种基于变换域特性的快速帧内预测模式选择算法。该算法有效地减少了原始图像帧内编码过程中进行帧内预测模式选择时待测编码模式的数量,在图像质量基本没有变差的情况下大大地提高了编码速度。

A fast H.264 Intra prediction mode selection scheme based on transform domain feature is proposed in this work.The proposed method effectively filter out the majority of candidate modes in intra coding.It is demonstrated by experimental results that the proposed algorithm can speed up the coding module with little quality degradation.
