ADAPTIVE INTRA SECONDARY TRANSFORM SET SELECTION AND SIGNALING

原文（中文）

The various implementations described herein include methods and systems for coding video. In one aspect, a method includes receiving a video bitstream comprising a plurality of blocks that includes a current block. The method also includes determining an intra prediction mode for the current block and selecting a secondary transform set from a plurality of secondary transform sets based on coded information comprising the intra prediction mode of the current block. The method further includes reconstructing the current block by applying a secondary transform from the selected secondary transform set.
