LUMA MAPPING-BASED VIDEO OR IMAGE CODING

WIPO Patent Application WO/2020/256393

A1

According to the disclosure of the present document, a procedure of deriving indexes for inverse luma mapping and/or chroma residual scaling can be simplified, and linear LMCS can be applied. Therefore, the complexity of LMCS can be reduced, and the efficiency of video/image coding can be increased.
