Title:
COLOR CORRECTION MATRIX OPTIMIZATION METHOD AND APPARATUS, AND ELECTRONIC DEVICE AND MEDIUM
Document Type and Number:
WIPO Patent Application WO/2024/027090
Kind Code:
A1
Abstract:
Disclosed in the embodiments of the present application are a color correction matrix optimization method and apparatus, and an electronic device and a medium. The method comprises: on the basis of a color correction matrix, performing correction processing on a color source matrix of a collected color card image, so as to obtain a color output matrix; determining a global hue error and a saturation constraint regular term according to Lab coordinates of the color output matrix and Lab coordinates of a color target matrix of a target color card image, and constructing a loss function; and updating the color correction matrix according to a loss function value until the loss function value converges, so as to obtain an optimal color correction matrix, such that on the basis of the optimal color correction matrix, color correction is performed on an image to be processed.
