Abstract
Aspects of the disclosure provide methods and apparatus for video decoding. Processing circuitry of the apparatus decodes coded information for a reconstructed sample of a current component in a current picture from a coded video bitstream. The coded information indicates a sample offset filter to be applied to the reconstructed sample. A filter shape of the sample offset filter is one of a plurality of filter shapes. Each of the plurality of filter shapes includes first reconstructed samples of a first component in the current picture. A filtered sample value of the reconstructed sample is determined based on the first reconstructed samples in the filter shape. The sample offset filter is an in-loop filter by which the output value is applied to the reconstructed sample as an offset to filter out coding artifacts while retaining details of the current component in the current picture.
