Title:
IMAGE CODING METHOD BASED ON CHROMA DEBLOCKING PARAMETER INFORMATION FOR MONOCHROME COLOR FORMAT IN VIDEO OR IMAGE CODING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/201551
Kind Code:
A1
Abstract:
According to a disclosure of the present document, information associated with a deblocking filter for performing deblocking filtering may include chroma component filter parameter information associated with deblocking parameter offsets that are applied to a chroma component. The chroma component filter parameter information may be selectively signaled on the basis of a chroma tool offset presence flag. Therefore, an effect of increasing overall coding efficiency may be derived by signaling chroma component filter parameter information only in the case of not a monochrome color format.
