Short distance intra coding scheme for high efficiency video coding.

This paper proposes a new intra coding scheme, known as short distance intra prediction (SDIP), for high efficiency video coding (HEVC) standardization work. The proposed method is based on the quadtree unit structure of HEVC. By splitting a coding unit into nonsquare units for coding and reconstruction, and therefore shortening the distances between the predicted and the reference samples, the accuracy of intra prediction can be improved when applying the directional prediction method.
