Abstract

The invention discloses a model training method, a color difference correction method, a device, a medium and electronic equipment, and relates to the technical field of image processing. The model training method includes: using a coefficient matrix to construct a mapping model between the original color information value of the image and the standard color information value; establishing an objective function of the mapping model based on a regular term with variable exponents; determining a plurality of sample images Original color information values ​​and standard color information values; using the original color information values ​​and standard color information values ​​of the plurality of sample images to calculate the objective function to determine the coefficient matrix. The disclosure utilizes the objective function established by the regular term of variable exponent, so that the model has stability while having high precision, thereby helping to improve the accuracy of chromatic aberration correction.

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...
