Huang Shi-tan · Modern Electronics Technique · 2008
Fast intra-prediction model selection is an important technology which can improve the encoding capability for H.264/AVC.It is possible to adopt the Rate-Distortion Optimized(RDO) mode in H.264 to maximize the coding gain at the cost of a very high computational complexity.To solve this problerm,fast intra-prediction algorithm for H.264/AVC is discussed firstly in this paper.Then some different fast algorithms are analyzed.It is demonstrated that they all reduce the intra-prediction time greatly,and it maintains high prediction precision and subjective picture quality.
