Video decoding method and device by local luminance compensation, Video encoding method and device by local luminance compensation

摘要

During a video encoding and decoding process, an available block among neighboring blocks neighboring the current block in the same frame as the current block is determined, local luminance compensation information is derived from the available block, and the local luminance compensation information is A method and apparatus for determining a local luminance compensation model based on the local luminance compensation model and applying the local luminance compensation model to the current block are proposed.
