Title:
VIDEO OR IMAGE CODING BASED ON MAPPING OF LUMA SAMPLES AND SCALING OF CHROMA SAMPLES
Document Type and Number:
WIPO Patent Application WO/2020/262952
Kind Code:
A1
Abstract:
According to the disclosure of the present document, the resources necessary for an LMCS process may be reduced by limiting the range that an LMCS APS occupies in all APSs. Thus, the degree of complexity in LMCS may be reduced, and video/image coding efficiency may be increased.
