Abstract

The intra prediction algorithm is one of the key algorithms provided by H.264, which contributes to high compression ratio. Unfortunately it considerably increases the complexity of the encoder. A fast intra prediction algorithm is proposed based on the existing algorithms, in which last prediction mode is the prior consideration for current predict mode. It has been simulated with Matlab. Experimental results show, comparing to the search algorithm presented by JM code, the proposed algorithm can reduce approximately 41 and 59 percent of the cost of mode search and achieve about 93 and 63 percent of precision on the average for 4×4 and 16×16 prediction mode, respectively.
