EE2-2.2: Occurrence-based intra coding (OBIC)
Abstract
This contribution reports the results of EE2-2.2 exploration experiment investigating the occurrence-based intra coding (OBIC) mode which is originally proposed in JVET-AG0141. The OBIC method derives the intra prediction modes based on the occurrence of the intra modes in the spatial neighborhood of the block. The proposed method uses blending of up to five intra modes, with highest occurrence, along with the planar mode or block vector based prediction to obtain the prediction of the block. The blending weights are decided based on each mode’s occurrence in the neighborhood.
