Abstract
Aspects of the disclosure provide methods and apparatuses for video encoding/decoding. In some examples, an apparatus for video decoding includes receiving circuitry and processing circuitry. The processing circuitry receives coded information of a current block in a current picture from a coded video bitstream, the coded information is indicative of applying local illumination compensation (LIC) on the current block according to a reference block in a reference picture. The processing circuitry constructs a parameter set list for the LIC, the parameter set list comprising a plurality of parameter sets for the LIC, and determines a selected parameter set from the parameter set list according to an index that is decoded from the coded video bitstream. The processing circuitry performs the LIC on the current block based on the selected parameter set to generate compensated samples of the current block according to the reference block in the reference picture.
