Constraints on Model-Based Transformation in Video Processing

摘要

performing a transition between the video and a coded representation of video comprising one or more video regions, wherein the coded representation includes transformation model information applicable to an in-loop transformation (ILR) of some of the one or more video regions. wherein the transform model information provides information about reconstruction of a video unit of a video region based on a representation in the first domain and the second domain, and/or a scaling of a chroma residual of the chroma video unit, and the transform model information comprises: A video processing method is provided, comprising a parameter set comprising a syntax element specifying a difference between a maximum bin index allowed and a maximum bin index to be used for reconstruction, wherein the parameter is within a range.
