- Abstract
- High efficiency video coding (HEVC) improves coding efficiency significantly relative to previous standards. But the computational complexity also increases drastically. Much of the complexity increase is due to the intra coding. In this paper, we propose a novel algorithm which utilizes the similarity among the reference samples to accelerate the intra mode decision. The encoding time saving can be up to 33% and 19% on average with acceptable increased BD rate and decreased BD Y-PNSR. ? 2015 IEEE.
