AI Technical Summary
Technical Problem
Existing video encoding and decoding technologies are inefficient when processing local lighting changes in videos, making it difficult to effectively perform local lighting compensation.
Method used
By introducing local lighting compensation (LIC) technology in video processing, the LIC type is determined based on the proximity reconstruction sample of the video unit, and converted and compensated according to the determined LIC type.
Benefits of technology

Abstract
Embodiments of the present disclosure provide a video processing solution. A method for video processing is presented. The method comprises: for a conversion between a video unit of a video and a bitstream of the video unit, determining a local illumination compensation (LIC) type of the video unit based on at least one neighboring reconstructed sample of the video unit; and performing a conversion based on the determined LIC type.
