Abstract
Aspects of the disclosure provide methods and apparatuses for filtering in video encoding/decoding. In some examples, an apparatus for video filtering includes processing circuitry. The processing circuitry determines a first offset value for applying a non linear mapping based filter based on first reconstructed samples at a first node in a loop filter chain. Then, the processing circuitry applies the first offset value to an intermediate reconstructed sample at a second node along the loop filter chain to generate a second reconstructed sample.
