Abstract

There are provided methods and apparatus for illumination compensation of intra-predicted video. An apparatus includes an encoder for encoding a picture using non-local intra prediction. The encoder includes an illumination compensation processing unit for applying illumination compensation to predicted data obtained from the non-local intra prediction. Another apparatus includes a decoder for decoding a picture using non-local intra prediction. The decoder includes an illumination compensation processing portion for applying illumination compensation to predicted data obtained from the non-local intra prediction.
