Fast and efficient video coding intra mode determining method

The invention discloses a fast and efficient video coding intra mode determining method. The fast and efficient video coding intra mode determining method includes the steps of prediction manner configuration and prediction mode selection. According to the prediction mode selection, the correlations between brightness intra prediction modes of a current CU layer and brightness intra prediction modes of CU layers above the current CU layer, the correlation between CBF and TU segmentation depth, and the correlations between chroma intra prediction modes of adjacent CU layers are utilized, and redundant intra mode prediction can be skipped, and therefore, coding computation complexity can be decreased. According to the correlation between a cost function and RDcost and the correlations between chroma intra prediction modes and brightness intra prediction modes, a minimum-cost prediction mode and an optimal brightness prediction mode in RMD are added in a brightness and chroma intra prediction process, and therefore, video coding efficiency and video quality can be ensured. Compared with high efficiency video coding (HEVC) standards in the prior art, the fast and efficient video coding intra mode determining method of the invention can greatly decrease coding computation complexity under the premise that bit rate and video quality are almost unchanged.
