Method and apparatus for using an intra prediction coding tool for intra prediction of non-square blocks in video compression
A method for video decoding includes determining whether an angular intra prediction mode for a current block is a wide angle mode that is spaced apart from a vertical mode and a horizontal mode by an angular distance that is more than a predetermined threshold. The method further includes, in response to the determination that the angular intra prediction mode is the wide angle mode, determining a non-wide angle mode that corresponds to the wide angle mode, the non-wide angle mode being spaced apart from the vertical mode or the horizontal mode by an angular distance that is less than or equal to the predetermined threshold. The method includes determining whether a coding tool is specified for the determined corresponding non-wide angle mode, and, in response to the determination that the coding tool is specified for the determined corresponding non-wide angle mode, using the coding tool in a decoding process.
