Abstract:
A method and apparatus of Intra prediction filtering in an image or video encoder or decoder are disclosed. The method comprises receiving input data associated with a current block ( 1110 ); determining a current Intra prediction mode belonging to a set of available Intra prediction modest for the current block ( 1120 ); according to the current Intra prediction mode, determining an initial Intra prediction block consisting of initial Intra prediction pixel values based on neighboring reconstructed samples of the current block ( 1130 ); applying Intra prediction filter to the initial Intra prediction block according to a current scanning order selected from multiple scanning orders depending on the current Intra prediction mode to generate a filtered Intra prediction block consisting of filtered Intra prediction pixel values, wherein inputs to the Intra prediction filter comprise a current pixel and one or more adjacent pixels, and said multiple scanning orders comprise at least two scanning orders selected from a vertical scanning order, a horizontal scanning order and a diagonal scanning order ( 1140 ); applying mode-dependent Intra prediction encoding or depending to the current block using the filtered Intra prediction block as a predictor for the current block ( 1150 ).

Claim (Index 3):
The method of  claim 1 , wherein the Intra prediction filter is enables or disabled according to a flag.
