Abstract:
A method for video decoding includes determining, for a current block that is a non-square 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 top right diagonal direction of the current block. The method further includes, in response to determining that the angular intra prediction mode is the wide angle mode, determining whether a condition to apply an intra smoothing filter to blocks neighboring the current block is satisfied. The method further includes, in response to determining that the condition is satisfied, applying the intra smoothing filter to the blocks neighboring the current block. The method also includes performing intra prediction based on the filtered blocks to obtain a characteristic value for the current block.

Claim (Index 17):
A non-transitory computer readable medium including instructions stored therein, which when executed by a processor in a video decoding apparatus, causes the processor to execute a method comprising:\n determining, for a current block that is a non-square 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 top right diagonal direction of the current block; in response to determining that the angular intra prediction mode is the wide angle mode, determining whether a block size of the non-square block is less than a block size threshold; in response to determining that the block size of the non-square block is less than the block size threshold, enabling an intra smooth filter and applying the enabled intra smoothing filter to blocks neighboring the current block; and performing intra prediction based on the filtered blocks to decode the current block, the performing the intra prediction further including:\n (i) determining whether a coding tool that utilizes the filtered blocks for performing the intra prediction supports the wide angle mode, \n (ii) in response to the determination that the coding tool does not support the wide angle mode, changing the angular prediction mode from the wide angle mode to an intra prediction mode included in the range of directions that spans the bottom left diagonal direction and top right diagonal direction of the current block, and \n (iii) in response to the determination that the coding tool does support the wide angle mode, decoding the current block in accordance with the wide angle mode.
