Color-balancing methods can solve the problems caused by light changes. Color-balancing models increase the visibility of the image by changing color and clarity. The study aims to examine the images of physiological disorders in apples' classification performances of images in different light colors with color-balancing models with pre-trained CNN models. Physiological disorders were classified with 0.949 accuracies in the ResNet50V2 model and sharpness data set in the green light color. With the proposed approaches, there was an increase in performance compared to the original data set. The best success in all light colors is in the sharpness data set type. In addition, the quality of the images was measured using MSE, PSNR, and SSIM. PSNR increased in the warm and cold white sharpness data set type and green light CLAHE data set type. Finally, experimental studies have shown that color balancing significantly affects classification success.eninfo:eu-repo/semantics/closedAccessConvolutional neural networkColor balancingClassificationLight colorsImage qualityConstancyArticle10.1007/s00530-023-01084-z2-s2.0-85151288670
