Abstract
Systems, methods, and instrumentalities are disclosed for performing local illumination compensation (LIC) with multiple linear models. In an example, a device, such as a video decoding device, or a video encoding device, may determine that sub-partition-based local illumination compensation (sub-LIC) is enabled for a current block. The device may divide the current block into a plurality of sub-partitions. The device may identify a plurality of templates associated with the plurality of sub-partitions. The device may derive a plurality of local illumination compensation (LIC) parameter sets associated with the plurality of sub-partitions based on the plurality of templates associated with the plurality of sub-partitions. The device may process (e.g., encode and/or decode) the current block based on the plurality of LIC parameter sets.
