Abstract:
1. An apparatus, comprising: a hardware encoder for encoding a picture using non-local intra prediction, wherein non-local intra prediction uses decoded areas of a current picture as predicted data for current data being encoded, and wherein said encoder includes an implicit illumination compensation processing portion for applying illumination compensation to predicted data obtained from the non-local intra prediction, wherein the illumination compensation is modeled to obtain a resultant model, and parameters of the resultant model are derived using linear regression from a non-local picture data prediction technique that minimizes a distance between luminance and chrominance data to be encoded and luminance and chrominance data of a weighted and offset predicted signal and uses information located beyond local neighboring data within a decoded portion of the picture, wherein the parameters of the resultant model are implicitly signaled to a corresponding decoder.
