Title:
FILTERING-BASED VIDEO OR IMAGE CODING COMPRISING MAPPING
Document Type and Number:
WIPO Patent Application WO/2020/197207
Kind Code:
A1
Abstract:
According to the disclosure of the present document, LMCS data and/or an ALF parameter can be signaled on the basis of type information from a parameter set. A default LMCS model comprised in the parameter set can be selectively used for an LMCS procedure. Therefore, the amount of data to be signaled for video/image coding is reduced and coding efficiency can be increased.
