Systems and methods for performing intra prediction coding in video coding

Abstract

This disclosure relates to video coding and more particularly to techniques for performing a position-dependent intra prediction sample filtering process. In one example, a method of coding video data comprises: deriving an intra prediction angle parameter; deriving an inverse angle parameter based on the intra prediction angle parameter; for a prediction mode included in a defined set of prediction modes, setting a value of a scale variable based on the derived inverse angle; and performing a position-dependent intra prediction sample filtering process using the value of a scale variable.
