The selection algorithm for Intra-prediction of H.264/AVC is analyzed,and the PAN′s algorithm is improved by using sub-sample method to compute the direction of the edge,by computing the amplitude of the edge vector to predict the mode and an early termination mechanism being proposed for the mode selection of Intra_4×4 on certain condition.Experimental results show that the proposed algorithm can reduce the coding time and encoder complexity while maintaining similar PSNR and bite rate.
