Title:
CONSTRAINING CONVOLUTION MODEL COEFFICIENT
Document Type and Number:
WIPO Patent Application WO/2024/027566
Kind Code:
A1
Abstract:
A method for performing cross component prediction by constraining the coefficients of a component prediction model is provided. A video coder receives data for a block of pixels to be encoded or decoded as a current block of a current picture of a video. The video coder derives a set of coefficients based on corresponding input and output component samples. The video coder constrains the derived set of coefficients based on a set of constraints. The video coder applies the constrained set of coefficients as a component prediction model to generate a predictor for the current block. The video coder encodes or decodes the current block by using the generated predictor.
