In H.264/AVC, intra prediction is one of the key processes that determine the coding performance. This paper mainly studies fast algorithms for intra prediction mode selection in H.264/AVC, aiming to improve the coding efficiency and real-time performance of video coding. Firstly, the coding principles of H.264/AVC and the process of intra prediction mode selection are introduced in detail. Then, the advantages and disadvantages of the currently used intra prediction mode selection algorithms are analyzed, and a new fast algorithm for intra prediction mode selection is proposed. The proposed algorithm uses the method of prior judgment and accelerated search to quickly select the optimal prediction mode, avoiding redundant calculations and unnecessary judgment in traditional algorithms, and improving the coding efficiency and real-time performance.Keywords: H.264/AVC; intra prediction; mode selection; fast algorithm
