Method and apparatus for video coding with primary and secondary transforms
Aspects of the disclosure provide method and apparatus for video coding. In some examples, an apparatus includes processing circuitry. The processing circuitry determines an intra prediction mode for generating a prediction image of a current block, determines one or more primary transforms according to signaling information that is extracted from a coded video bitstream, and determines a secondary transform according to the determined intra prediction mode and the determined one or more primary transforms. The processing circuitry also reconstructs a residue image of the current block based on one or more coefficients of an input block extracted from the coded video bitstream, the determined one or more primary transforms, and the determined secondary transform. The processing circuitry then reconstructs an image of the current block based on the prediction image and the residue image of the current block.
