Integration of Plane Mode with Multiple Predictor Sets in Intra Prediction for video coding

Current default intra prediction method in the current test model for the next generation video coding standard JCT-VC, Unified Intra Prediction, has up to 33 directional modes and only one non-directional mode, which is Intra DC mode.

Summary:Current default intra prediction method in the current test model for the next generation video coding standard JCT-VC, Unified Intra Prediction, has up to 33 directional modes and only one non-directional mode, which is Intra DC mode. Having only one non-directional mode is insufficient for maintaining accuracy on prediction units with complex texture. In this contribution, Plane Mode is integrated as an additional non-directional mode and an improved Multiple Predictor Set method is introduced; the proposed new method for intra mode prediction is used to obtain higher accuracy for intra mode prediction in video coding. Experimental results have shown that coding efficiency is improved with the proposed method.
