Abstract

In the previous work [2], we proposed an error diffused intra prediction for HEVC to improve its coding performance. The proposed algorithm can achieve average 0.5% BDBR reduction with 21% increase of encoding time, compared to the HEVC intra prediction. To further improve the computation efficiency, in this paper, we suggest incorporating ordered dither technique into HEVC intra prediction to reduce computational complexity, instead of error diffusion. The experimental results reveal that average 0.5% BDBR reduction can be achieved in the proposed algorithm and it brings out only an increase of average 4% of total encoding time compared to the HEVC intra prediction, and that is much lower than the error diffused intra prediction.
