METHOD OF ADAPTIVE INTRA PREDICTION MODE ENCODING AND APPARATUS FOR THE SAME AND METHOD OF DECODING AND APPARATUS FOR THE SAME

摘要

Disclosed is an intra prediction mode encoding method and apparatus capable of increasing the compression efficiency of intra prediction mode encoding. The intra prediction mode encoding method includes detecting a similarity of a prediction direction for a current block of the neighboring block and the similarity, and the number of candidate prediction modes based on the position of the neighboring block for the current block and the intra prediction direction of the neighboring block. And determining a candidate prediction mode of the current block based on (N). Therefore, unlike the conventional technique, where only global statistic was considered, the information on the intra prediction mode of the current block is more accurately and efficiently compressed considering local statistic to improve the intra encoding performance of the image. I can do it.
