Multiple modes intra-prediction in intra coding
Peng Zhang, Dandan Zhao, Siwei Ma, Yan Lu, Wen Gao · 2004
Intra-prediction is a widely used technique in intra coding. In H.264, nine directional prediction modes are used, and in AVS (audio-video coding standard of China), six modes are used. The paper proposes a multiple mode, intra-prediction scheme to achieve a better balance between prediction precision and side information cost. Three kinds of additional modes are introduced to increase prediction precision from different aspects. A significant performance gain can be achieved using this multiple mode intra-prediction, with little complexity increase.
