Fast Intra-prediction Mode Selection Algorithm for H.264
Ming Feng · 2008
H.264 introduces intra-prediction coding technique to improve the intra-coding efficiency.This enormously increases the computational complexity. In order to decrease the computational complexity of the algorithm,a fast algorithm for intra-prediction mode decision based on pixel's edge vector's variance,the relation between sub-block's mode and macro-block's mode. Experimental results show that compared with the original intra-prediction coding scheme,the proposed algorithm reduce the computational complexity of intra-prediction coding dramatically with only trivial loss of PSNR and increment of bite-rate.
