Abstract:
Methods and apparatuses for intra prediction in video encoding and decoding using a blended intra predictor are described. In one exemplary embodiment, intra prediction is preformed using a blended intra predictor for a pixel of a current block being encoded and decoded. The blended intra predictor is determined by summing with corresponding weights a predictor using the intra prediction direction to be used for the current block and one or more predictors using the one or more corresponding intra prediction directions of the one or more neighboring blocks. The corresponding weights for the one or more neighboring blocks decrease with increased distance of the pixel to the one or more neighboring blocks.
