Abstract
Aspects of the disclosure provide methods and apparatuses for video encoding/decoding. In some examples, an apparatus for video decoding includes processing circuitry. For example, the processing circuitry determines a first combination from reconstructed samples of a first color component within a filter support region. Then, the processing circuitry determines, based on a mapping that associates offset values with combinations of possible reconstructed sample values, a first offset value that is associated with the first combination, and applies the first offset value on a to-be filtered sample of a second color component in the filter support region to determine a filtered sample of the second color component.
