Video decoding method and apparatus by conditional applied local luminance compensation, Video encoding method and apparatus by conditional applied local luminance compensation

摘要

During the video encoding and decoding process, the local luminance compensation is determined based on the information on whether the neighboring block neighboring the current block is applied or not, and if it is determined to apply the local luminance compensation, the local luminance compensation model is determined. Then, a method and apparatus for applying local luminance compensation to the current block using the determined luminance compensation model are proposed.
