Abstract
In order to improve the visibility of foggy images, this paper uses two models to iteratively refine the image. In the first model, the image is first enhanced by histogram equalization and then enhanced by the Retinex algorithm. In the second model, the image is firstly enhanced with the Retinex algorithm, and then the gamma correction is used to adjust the brightness. From a theoretical analysis and practical experiments, this method improves the sharpness of the image while enhancing the image detail information and restoring the image color.
