Harmonized Local Illumination Compensation and Modified Inter Coding Tools - A simplified explanation of the abstract
This abstract first appeared for US patent application 18358747 titled 'Harmonized Local Illumination Compensation and Modified Inter Coding Tools
Simplified Explanation
- The patent application describes a method for video processing that involves determining whether to use a local illumination compensation (LIC) mode for converting a current block of a video region. - The LIC mode uses a linear model of illumination changes in the current block during the conversion process. - The determination of whether to use the LIC mode is based on an inheritance rule, which specifies inheriting the use of the LIC mode from a base merge candidate of an ultimate motion vector expression (UMVE) mode. - The UMVE mode involves using a motion vector expression that includes a base merge candidate and motion vector differences to refine the motion information of the base merge candidate.
Original Abstract Submitted
A method for video processing is provided to include: determining, based on an inheritance rule, whether to use a local illumination compensation (LIC) mode for a conversion between a current block of a video region of a video and a coded representation of the video, and performing the conversion based on the determining. The LIC mode includes using a linear model of illumination changes in the current block during the conversion. The inheritance rule specifies to inherit a use of the LIC mode from a base merge candidate of an ultimate motion vector expression (UMVE) mode, and the UMVE mode includes using a motion vector expression that includes a base merge candidate and motion vector differences utilized to refine the motion information of the base merge candidate.
