摘要

The present disclosure relates to a cross component prediction and method for deriving a linear model for obtaining a first component sample of a first component block from an associated reconstructed second component sample of a second component block within the same frame;This wayIncluding determining the parameters of linear equations representing straight lines passing through two points;Each point is defined by two variablesBased on the reconstruction samples of both the first and second componentsThe first variable corresponds to the second component sample value;The second variable corresponds to the first component sample value;Includes deriving linear models defined by linear parameters.WhereDetermining the parameters uses integer arithmetic.
