Abstract
A method of video decoding includes determining reconstructed samples of a first color component in a filter support region of a current picture that is a part of a coded video sequence, and performing a cross-component sample offset (CCSO) filter process on the reconstructed samples of the first color component in the filter support region to generate an output offset value. The method also includes scaling the output offset value based on the reconstructed samples of the first color component in the filter support region, and reconstructing samples of a second color component in the filter support region based on the scaled output offset value. The second color component is different from the first color component.
