Abstract: A video coder receives a Local Illumination Compensation (LIC) linear model that is generated using samples neighboring two different blocks. The linear model includes a scale factor and a y-intercept. The video coder adjusts the linear model by applying an offset to adjust the scaling factor (or slope) of the linear model. The scale factor or the y-intercept of the adjusted linear model may be clipped to stay within a defined range. The offset may be selected from a set of predefined values based on a syntax element that is signaled in a bitstream. The applied offset may be inherited from a previously coded position. When the current block is coded by bi- prediction, the linear model may be one of first and second linear models used to generate a predictor of the current block.
