Abstract
Aspects of the disclosure provide methods and apparatuses for video encoding/decoding. In some examples, an apparatus for filtering in video decoding includes processing circuitry. For example, the processing circuitry determines first reconstructed sample values of reconstructed samples of a first color component within a filter support region of a to-be filtered sample of a second color component. The to-be filtered sample is at a center position of the filter support region. Based on a mapping that associates offset values with reconstructed sample values within the filter support region, a first offset value of the offset values in the mapping that is associated with the first reconstructed sample values is determined. The first offset value is applied on the second color component for the to-be filtered sample to determine a filtered sample value of the second color component for the to-be filtered sample.
