H.264/AVC is the newest video coding standard with high compression efficiency. Especially it adopts traveling algorithm to find the optimal mode for intra-frame prediction in spatial field, so it is quite complex and costs very long encoding-time. In this paper, the proposed fast mode decision scheme consists of two parts: early intra mode detection, which is to select intra 4×4 or intra 16×16 mode...
H.264/AVC is the newest video coding standard with high compression efficiency. But because it adopts the traveling algorithm to find the optimal mode for intra-frame prediction in the spatial field, it is quite complex and costs very long time to encode. In this paper, according to the ID-histogram algorithm, it is possible to select Intra 4x4 or Intra 16x16 mode for every macro-block before encode...
H.264/AVC is the latest video coding standard with high compression efficiency. Due to its time-consuming in coding, it cannot meet the real-time application requirements. In this paper, an efficient algorithm was proposed based on 2D-histogram according to the feature of intra-frame prediction. In this algorithm, each macroblock is predicted before coding, and one of the two prediction modes is selected...
