Abstract: One or more intra mode predictors of a current block are determined, where the one or more intra mode predictors are derived based on the neighboring samples of the current block via either a decoder side intra mode derivation (DIMD) or a template-based intra mode derivation (TIMD). Whether a position dependent intra prediction combination (PDPC) is to be applied is determined based on the one or more intra mode predictors. In response to the determining that the PDPC is to be applied, a fusion process is performed on the one or more intra mode predictors to combine the one or more intra mode predictors into a single intra mode predictor. The PDPC is applied based on the single intra mode predictor to generate a modified predictor of the current block. The current block is reconstructed based on the modified predictor generated by the PDPC.
