Abstract
Image or video processing methods and apparatuses comprise receiving input data associated with a current picture or a current slice in the current picture, determining whether the current picture is a monochrome picture, conditionally signaling or parsing chroma deblocking parameters depending on whether the current picture is a monochrome picture, and encode or decode the current picture or current slice. The chroma deblocking parameters are used in a deblocking filter operation applied to chroma components of the current picture or current slice when the current picture is not a monochrome picture. A syntax element may be used to indicate derivation of chroma deblocking parameters, and based on a value of the syntax element, the chroma deblocking parameters are allowed to be explicitly signaled in or parsed from a syntax structure, or the chroma deblocking parameters are implicitly inferred.
