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 7):
The method of  claim 4 , wherein when the flag is explicitly signalled in a bitstream, the flag is signalled in syntax level or header corresponding to a sequence, view, picture, slice, SPS (Sequence Parameter Set), VPS (Video Parameter Set), APS (Adaptation Parameter Set), CTU (coding tree unit), CTB (coding tree block), LCU (largest coding unit), CU (coding unit), PU (prediction unit), TU or a combination thereof.
