Abstract:
Flag information associated with the current block is obtained in coded information, which indicates whether the current block is intra predicted based at least in part on an intra mode derivation. In response to the flag information being true, a plurality of candidate intra modes is determined based on neighboring samples of the current block. A first intra mode of the current block is determined based on a first syntax element that is included in the coded information. The first syntax element indicates the first intra mode of the current block from a most probable mode (MPM) list and a MPM remainder. A second intra mode of the current block is determined based on the first intra mode and the plurality of candidate intra modes. The current block is reconstructed based on the first intra mode and the second intra mode.
