In order to reduce the complexity of the H.264 coding algorithm, a fast intra-frame mode selection algorithm is proposed. The macroblock prediction type is determined according to the characteristics of the adjacent pixel differences within the macroblock, and the Pan algorithm based on the edge direction histogram is improved. The improved algorithm is used to predict the macroblocks with the selected prediction type and select the best prediction mode. Experimental results show that the algorithm reduces the encoding time by an average of 71.6% while ensuring the distortion rate and bit rate performance, greatly improving the coding efficiency. Keywords: H.264 standard; intra-frame prediction; prediction mode selection
