Systems and methods of determining illumination compensation parameters for video coding
Techniques and systems are provided for coding video data. For example, a method of coding video data includes determining one or more illumination compensation parameters for a current block and coding the current block as part of an encoded bitstream using the one or more illumination compensation parameters. In some cases, the method can include determining one or more spatially neighboring samples for the current block and deriving the one or more illumination compensation parameters for the current block based on at least one of the one or more spatially neighboring samples. The method can further include signaling, individually, for the current block, an illumination compensation status in the encoded bitstream. The method can further include signaling at least one of the one or more illumination compensation parameters for the current block in the encoded bitstream.
