Abstract
In this contribution, it is proposed to adaptively replace several conventional angular intra prediction modes with wide-angle intra prediction modes for non-square blocks. The total number of angular directions for any block remains the same as in VTM/BMS. For directions with wide angles, reference sample smoothing is performed. On top of VTM, the simulation results reportedly show luma BD-rate variation of -0.32% and -0.17% on average in All Intra (AI) and Random Access (RA) configuration.
