Construction of Luma-dependent Chroma Residual Scaling for Video Coding

摘要

A video processing method is provided, comprising: performing a transition between a current video block of video that is a chroma block and a coded representation of the video, wherein during the transition, the current video block is divided into a first domain and a second domain Constructed based on two domains, the transition further includes applying a forward reshaping process and/or an inverse reshaping process to one or more chroma components of the current video block.
