Model training method, color difference correction method and device, medium and electronic equipment

Abstract

The invention discloses a model training method, a color difference correction method and device, a medium and electronic equipment, and relates to the technical field of image processing. The model training method comprises the following steps: constructing a mapping model between an original color information value and a standard color information value of an image by utilizing a coefficient matrix; Establishing an objective function of the mapping model based on the regular term of the variable exponent; Determining original color information values and standard color information values ofthe plurality of sample images; And calculating the objective function by using the original color information values and the standard color information values of the plurality of sample images so asto determine the coefficient matrix. According to the method and the device, the target function established by the regular term of the variable exponent is utilized, so that the model has stability under the condition of higher precision, and the accuracy of color difference correction is improved.

Description

technical field [0001] The present disclosure relates to the technical field of image processing, in particular, to a model training method, a chromatic aberration correction method, a model training device, a chromatic aberration correction device, a storage medium and electronic equipment. Background technique [0002] As one of the most intuitive and basic features in image information, color information plays an important role in people's cognition and identification of objects. The color information of an object is usually determined by the relative spectral power distribution of the illumination source, the reflectivity of the object, and the color vision characteristics of the observer. [0003] However, the spectral tristimulus values ​​of the imaging system sensor for the three primary colors of red, green, and blue are different from the spectral tristimulus values ​​determined by the standard chromaticity observer, resulting in color differences between the acquir...
