Abstract
HEVC (high efficiency video coding) achieves much higher coding efficiency compared with previous video coding standards at cost of significant computational complexity. This paper proposes a fast intra mode decision scheme, where a Bayesian classification framework using relative sum of absolute Hadamard transformed difference (SATD) is introduced and combined with conventional fast encoding methods. Experimental results show that this scheme reduces encoding run time by about 30% with a negligible coding loss of 0.9% BD-rate for the all intra coding scenario.
