Local lighting compensation for video encoding and decoding using stored parameters

摘要

Local illumination compensation systems for video encoding and decoding use memory to store illumination compensation parameters and do not require access to reconstructed pixels of neighboring blocks. The set of illumination compensation parameters have a limited size and are stored in a dedicated buffer that is separate from the coding unit level storage of information. The buffer contains a set of illumination compensation parameters that can be calculated in an on-the-fly basis (or determined in some other way) or pre-determined (e.g., can be obtained from a video signal or from a device). do.
