SIMPLIFIED SIGNALING METHOD FOR AFFINE LINEAR WEIGHTED INTRA PREDICTION MODE

摘要

Aspects of the disclosure provide methods and apparatuses for video encoding/decoding. In some examples, an apparatus for video decoding includes processing circuitry that decodes prediction information for a current block in a current picture that is a part of a coded video sequence. The prediction information indicates whether the current block is coded in affine linear weighted intra prediction (ALWIP). Responsive to the prediction information indicating that the current block is coded in ALWIP, the processing circuitry determines an ALWIP mode index irrespective of prediction modes of neighboring blocks adjacent to the current block, the ALWIP mode index indicating one of a plurality of ALWIP modes. The processing circuitry reconstructs the current block according to the one of the plurality of ALWIP modes.
