Shen Liquan · Journal of Sichuan University · 2007
A new H.264 fast intra prediction algorithm was proposed to improve the encoder speed using three criterion,such as mode correlation of neighboring macroblocks,early termination based on all zero block detection,and the prediction of intra-mode size using texture feature of macroblock.The simulation results showed that, compared with full search algorithm,the encoding frames per second(fps) of the proposed algorithm increases 42.45%～73.71% with similar coding efficiency.Compared with FIPAMP algorithm,the fps of the proposed algorithm increases 23.19%～55.83% with similar coding efficiency.
