Original Abstract Submitted
A method for video decoding is provided. For a current block, whether an angular intra prediction mode for the current block is a wide angle mode that is in a direction outside of a range of directions that spans a bottom left diagonal direction and a top right diagonal direction of the current block is determined. Based on the angular intra prediction mode being determined as the wide angle mode, an intra smooth filter is enabled, the enabled intra smooth filter is applied to blocks neighboring the current block to generate filtered blocks, and intra prediction is performed based on the filtered blocks to decode the current block.
