AI Technical Summary

Problems solved by technology

However, the TV model has some shortcomings, such as staircase effect, blurred corners, low image contrast, etc. In addition, due to the inconsistent diffusion effect between different channels, the processed image will have blurred edges, and the edge preservation effect is not good.

Abstract

The invention discloses an image defogging method and system, electronic equipment and a computer readable storage medium, and the method comprises the steps: obtaining an original image, and calculating the atmospheric light value and transmissivity of the original image by using a dark channel prior principle; and inputting the original image, the atmospheric light value and the transmissivity into a second-order variation model to obtain a defogged image. Therefore, according to the image defogging method provided by the invention, the foggy image can be effectively restored, the noise problem existing after defogging processing can be effectively reduced while the clear image is obtained, and meanwhile, the original edge characteristics of the scene can be kept.

Description

technical field [0001] The present application relates to the technical field of image processing, and more specifically, to an image defogging method and system, an electronic device, and a computer-readable storage medium. Background technique [0002] In foggy weather conditions, the atmosphere contains a large number of tiny particles or suspended water droplets, which cause light to scatter, refract, absorb and other reactions during the propagation process, resulting in reduced contrast and fine details of the images collected by the device in outdoor scenes. The loss of information leads to a decline in image quality, which seriously affects the application of outdoor computer vision systems such as road monitoring, environmental monitoring, and target recognition. Therefore, image defogging technology has important application value. [0003] He (dark channel prior combined with guided filter dehazing) algorithm, as a commonly used dehazing algorithm at present, can...
