Title:
PARAMETER ACQUISITION METHOD, PIXEL POINT PAIR SELECTION METHOD, AND RELATED DEVICES
Document Type and Number:
WIPO Patent Application WO/2021/036462
Kind Code:
A1
Abstract:
Provided are a parameter acquisition method, a pixel point pair selection method, and related devices. The parameter acquisition method comprises: determining N pixel point sets corresponding to a chroma prediction block, and N pixel point sets corresponding to a brightness prediction block, wherein the chroma prediction block corresponds to the brightness prediction block, and N is an integer greater than one; and according to the N pixel point sets corresponding to the chroma prediction block, and the N pixel point sets corresponding to the brightness prediction block, acquiring N groups of parameters, wherein the N groups of parameters are used for predicting a chroma value of the chroma prediction block.
