Abstract

The invention discloses an image defogging method and device, equipment and a storage medium, and belongs to the technical field of digital image processing. The method comprises the following steps: performing two-dimensional wavelet decomposition on an original image to obtain a horizontal low-frequency component, a horizontal high-frequency component, a vertical low-frequency component and a vertical high-frequency component corresponding to the original image; carrying out defogging processing on the horizontal low-frequency component and the vertical low-frequency component to obtain a defogged horizontal low-frequency component and a defogged vertical low-frequency component; performing denoising processing on the horizontal high-frequency component and the vertical high-frequency component to obtain a denoised horizontal high-frequency component and a denoised vertical high-frequency component; and performing wavelet reconstruction on the defogged horizontal low-frequency component, the defogged vertical low-frequency component, the denoised horizontal high-frequency component and the denoised vertical high-frequency component to obtain a defogged image. According to the method and the device, the degradation phenomenon of the original image (foggy day image) is improved, and the definition of the image is improved.

Description

technical field [0001] The present application relates to the technical field of digital image processing, and in particular to an image defogging method, device, equipment and storage medium. Background technique [0002] At present, the processing methods for foggy images are mainly divided into two categories: foggy image restoration and foggy image enhancement. Among them, for image enhancement in foggy days, the Retinex algorithm is often used traditionally. The Retinex algorithm uses a Gaussian filter to estimate the illumination component of the image, which can easily cause the edge of the processed image to be blurred, the image is dim, and the details are lost and the color is easy to be distorted. Contents of the invention [0003] The main purpose of the present application is to provide an image defogging method, device, equipment and storage medium, aiming to solve the technical problem that the existing image enhancement method in foggy days tends to cause t...
