Intra-frame coding is one of the most important technologies in H.264/AVC, which made significant contributions to the enhancement of coding efficiency of H.264/AVC at the cost of computation complexity. To address this problem, in this paper we present an efficient VLSI implementation of a computation efficient intra prediction algorithm for H.264/AVC encoding. Unlike most of existing fast intra-mode...
Intra prediction applied in H.264 improve compression efficiency greatly of I frame. But the full search algorithm is computationally expensive and there exist conflict with some real time application and embedded systems just holding limited calculation resource. In order to promote prediction speed, a fast intra prediction algorithm is proposed which select appropriate intra prediction type based...
Intra prediction applied in H.264/AVC improves compression efficiency of I frame enormously. But the full search algorithm is of high computational expense, which conflicts with some real time application and embedded systems with limited calculation resources. In order to promote prediction speed, a fast intra prediction algorithm is proposed in this paper which selects appropriate prediction block...
This paper presents a fast mode decision algorithm for H.264 intra prediction based on dominant edge strength (DES). In H.264 intra prediction, the computation-extensive rate distortion optimization (RDO) technique with full intra mode search is used to select the best mode for each macroblock. To reduce the computational load in mode decision, the DES which is corresponding to a decision mode is...
