IMAGE CODING METHOD AND DEVICE FOR CARRYING OUT MRL-BASED INTRA PREDICTION: abstract simplified (18209310)

• This abstract for appeared for patent application number 18209310 Titled 'IMAGE CODING METHOD AND DEVICE FOR CARRYING OUT MRL-BASED INTRA PREDICTION'

Simplified Explanation

This abstract describes a method for decoding images. The method involves creating a list of potential ways to predict the content of a block in the image. The specific prediction mode for the block is determined based on information about the available prediction modes and the reference line used for prediction. Once the prediction mode is determined, prediction samples are generated for the block, and a reconstructed picture is created based on these samples. The method also includes including a DC mode in the list of potential prediction modes if the reference line index is not zero.

Original Abstract Submitted

An image decoding method includes: configuring a MPM list including candidate intra prediction modes for a current block; deriving an intra prediction mode of the current block from the MPM list on the basis of MPM index information indicating an intra prediction mode, among the candidate intra prediction modes included in the MPM list, for the current block; generating prediction samples for the current block on the basis of the intra prediction mode; and generating a reconstructed picture for the current block on the basis of the prediction samples, wherein the step for configuring the MPM list comprises, on the basis of the case where the value of reference line index information, representing a reference line used for the intra prediction of the current block, is not zero, deriving a DC mode as one mode among the candidate intra prediction modes, and including same in the MPM list.
