Method and apparatus for non-linear loop filtering
Aspects of the disclosure provide a method and an apparatus including processing circuitry for video decoding. The processing circuitry can decode coded information of a coding block in a picture of a coded video sequence. The coded information can indicate a clipping index m that indicates a clipping value for a filter that is applied to the coding block. The processing circuitry can determine the clipping value associated with the clipping index. The clipping value can be based on a multiplication of a first function and a second function. The first function is dependent on a bit depth B and is independent of the clipping index m, and the second function is dependent on the clipping index m and is independent of the bit depth B. The processing circuitry can generate a filtered coding block by applying the filter corresponding to the clipping value to the coding block.
