Description | ||||||
H.264, MPEG-4 Part 10, is the latest digital videocoding standard that achieves very high data compression byusing several new coding features. One of the key features isthe intra prediction based on the rate distortion optimization(RDO) procedure, which requires a true encoding of the intrablock by trying all intra prediction modes. The computationalburden of intra prediction with the RDO procedure isextremely high for real time applications. In this paper, wepropose a classified block type (CBT) algorithm that selects theappropriate intra block size and further our proposed biregionsimilarity detection algorithm(BSD) selected block thatreduces a number of candidate mode required for RDO whichsignificantly reduces the encoder complexity. Experimentalresults show that the proposed fast mode decision algorithmreduces the encoding time by about 68%, with negligible loss ofvideo quality. | ||||||
