Abstract

A non-transitory machine-readable medium of an electronic device storing computer-executable instructions for decoding a bitstream is provided. The computer-executable instructions, when executed by a processor of the electronic device, cause the electronic device to receive an image frame of the bitstream; determine a first mode from a plurality of local illumination compensation (LIC) modes; determine a first template of a block unit of the image frame and at least one second template of at least one reference block based on the first mode; determine a first model based on the first template and the at least one second template; obtain a slope adjustment parameter; adjust the first model based on the slope adjustment parameter; and modify a prediction illumination of the block unit of the image frame based on the adjusted first model.
