Original Abstract Submitted
In a method for video decoding, a determination, for a current block that is a non-square block, is made as to 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 top right diagonal direction of the current block. When the angular intra prediction mode is the wide angle mode, whether a block size of the non-square block is greater than 32 is determined. When the block size of the non-square block is greater than 32, an intra smoothing filter is enabled and the enabled intra smoothing filter is applied to blocks neighboring the current block to generate filtered blocks. Intra prediction is performed based on the filtered blocks to obtain a characteristic value for the current block.
