Title: Efficient intra-mode coding method in video coding
Abstract: This paper proposes an efficient intra-mode coding method using the deviation of neighbor pixels. In HEVC, the number of intra-prediction modes is increased in order to improve coding performance for intra-prediction as compared to H.264/AVC. However, this causes coding inefficiency in intra-mode coding. To improve coding efficiency, we propose a new intra-mode coding method that applies the analysis of the correlation between neighbor pixels and the intra-mode. Experimental results show that coding efficiency is improved by up to 0.80% in intra-mode coding. The proposed method also reduces an average 0.19% of the bitrate in the total codec as compared to HM4.0.
