This contribution presents an intra prediction method to produce natural pattern of prediction block by combining original and filtered reference pixels. Filtered reference is calculated with weighted summation of original reference pixels. The direction of reference filtering is determined by intra direction mode. Simulation results reportedly show average -0.12% luma BD-rate gain with 196% and 100% encoding and decoding time for all intra (AI), -0.02% luma BD-rate gain with 113% and 100% encoding and decoding time for random access (RA) based on VTM configuration.
