Title:
VIDEO SIGNAL PROCESSING METHOD USING LINEAR MODEL AND DEVICE THEREFOR
Document Type and Number:
WIPO Patent Application WO/2024/010430
Kind Code:
A1
Abstract:
A video signal decoding device comprises a processor, wherein the processor predicts a sample of a chroma component corresponding to a sample of a luma component of a current block on the basis of the sample of the luma component, and predicts the current block on the basis of a predicted value of the sample of the chroma component. The predicted value of the sample of the chroma component is obtained using a linear equation, and the linear equation may include a term for a gradient value of the sample of the luma component.
