Abstract

See full text

A method of controlling intra prediction for decoding or encoding of a video sequence, is by at least one processor and includes identifying whether an intra prediction mode of a current block has a wide angle direction, based on the intra prediction mode being identified to have the wide angle direction, filtering reference samples of the current block, using an edge-smoothing filter, and based on the intra prediction mode being identified to not have the wide angle direction, filtering the reference samples, using an edge-preserve filter.
