Method and apparatus for video coding using planar intra prediction mode for intra sub-partition coding mode
Aspects of the disclosure provide methods, apparatuses, and non-transitory computer-readable storage mediums for video encoding/decoding. Prediction information for a current block in a current picture that is a part of a coded video sequence is decoded. The prediction information indicates an intra sub-partition (ISP) mode for the current block. The ISP mode indicates that the current block is to be partitioned in one of a vertical mode and a horizontal mode. The current block is partitioned into a plurality of sub-partitions based on the ISP mode. Each sub-partition is associated with at least one different reference sample that is in one of (1) a row above the current block and (2) a column left to the current block. Each sub-partition is reconstructed based on the at least one different reference sample associated with the respective sub-partition. The current block is reconstructed based on the reconstructed plurality of sub-partitions.
