Original Abstract Submitted
Aspects of the disclosure include methods and apparatuses for video coding. One of the apparatuses includes processing circuitry that receives a current block in a bitstream. The current block is predicted with intra prediction fusion comprising multiple candidate intra prediction modes. The processing circuitry determines a respective candidate prediction value of a sample in the current block for each of the multiple candidate intra prediction modes. The processing circuitry derives weights of the respective multiple candidate intra prediction modes based on intra prediction modes used to code neighboring blocks of the current block. The processing circuitry predicts, according to the derived weights, the sample in the current block by a weighted sum of the candidate prediction values associated with the multiple candidate intra prediction modes.
