Abstract

A new fast intra-prediction mode selection algorithm based on spatio-temporal predicting for H.264 was pre-sented.Using the correlation of spatial and temproal domain in video sequence and constructing the probability histogram of intra prediction mode in the spatial and temporal domain

Pan’s algorithm based on edge direction histogram was im-proved.Experimental results show that the proposed algorithm can significantly reduce coding time and enhance the per-formance of H.264 while maintaining same image quality and output rate.
