- Abstract
- In this paper, we propose a lossless intra prediction by applying DPCM on the residuals. Since an additional DPCM on the residuals after pixel-by-pixel DPCM is applied, additional spatial redundancy is reduced in proposed method. Multiple residuals are used for additional DPCM of proposed method in contrast with conventional method. The experimental results show that the proposed method achieves the bit saving of 10.11% on average compared to HEVC lossless intra coding. The proposed method results in slightly better compression performance compared to conventional algorithm.
