AN ENCODER, A DECODER AND CORRESPONDING METHODS HARMONZTING MATRIX-BASED INTRA PREDICTION AND SECOUNDARY TRANSFORM CORE SELECTION

Document Type and Number:

WIPO Patent Application WO/2020/211765

Kind Code:

A1

Abstract:

A method of coding implemented by a decoding device or an encoding device, comprising: determining an intra prediction mode of a current block(1601); and determining selecting of a secondary transform of the current block based on the intra prediction mode determined for the current block(1603).
