Abstract :
Fast mode decision for intra mode prediction in H.264/AVC trades off between rate distortion performance and encoding complexity. Edge direction method has been certified available by reducing unlikely orientation features which are represented by eight values derived from pixel-value processing. In this paper, we proposed a new method to simplify this procedure by exploiting the correlation between these values. Experiment results demonstrate that 2.5% time reduction on average can be achieved without performance degradation.
