INTRA PREDICTION-BASED IMAGE CODING METHOD AND APPARATUS USING UNIFIED MPM LIST - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240244257 titled 'INTRA PREDICTION-BASED IMAGE CODING METHOD AND APPARATUS USING UNIFIED MPM LIST
The image decoding method described in the patent application involves acquiring reference line index information from a bitstream to determine the reference line for intra prediction of a current block. The method then constructs a most probable mode (mpm) list based on the reference line index information, derives the intra prediction mode of the current block from the mpm list, generates prediction samples for the current block, and generates restoration samples based on the prediction samples.

Original Abstract Submitted
an image decoding method according to the present document comprises the steps of: acquiring, from a bitstream, reference line index information indicating a reference line to be used for intra prediction of a current block; constructing a most probable mode (mpm) list by deriving candidate intra prediction modes of the current block on the basis of the value of the reference line index information; deriving the intra prediction mode of the current block on the basis of the mpm list; generating prediction samples for the current block on the basis of the intra prediction mode; and generating restoration samples for the current block on the basis of the prediction samples, wherein, on the basis of the case in which the value of the reference line index information is not zero, one of the candidate intra prediction modes is a dc mode and the number of candidate intra prediction modes including the dc mode is 5.
