Abstract: A method for using local illumination compensation (LIC) in video coding is provided. A video coder receives data to be encoded or decoded as a current block of pixels of a current picture of a video. The video coder inherits a previously used linear model that is derived based on template samples neighboring two or more previously coded blocks. The video coder applies the inherited linear model to an initial predictor of the current block to generate a final predictor of the current block. The video coder encodes or decodes the current block by using the final predictor. The video coder inherits the linear model by inheriting scaling and offset parameters, as well as information regarding the derivation of the linear model. The linear model may be a spatial candidate, a non-adjacent spatial candidate, a historical candidate, or a temporal candidate.
