Problems solved by technology

Methods based on image enhancement include contrast enhancement, methods based on Retinex theory, and image fusion. This type of image defogging method does not consider the cause of image degradation in foggy days, but only enhances the visual effect to a certain extent. This enhancement will be accompanied by s

Abstract

The invention relates to an image defogging method and system, electronic equipment and a storage medium. The method comprises the steps of obtaining a to-be-defogged original image; filtering the pixel value of the original image by adopting a pixel window function to obtain a mean value of the dark channel image; converting the original image into an HIS image; reconstructing the brightness of the HIS image in a table look-up mode according to the mean value to obtain a brightness reconstructed HIS image; sequentially carrying out brightness enhancement and brightness curve correction on theHIS image after brightness reconstruction to obtain a corrected HIS image; performing color saturation adjustment on the HIS image to obtain an adjusted HIS image; and according to the corrected HISimage and the adjusted HIS image, converting the corrected HIS image and the adjusted HIS image by adopting an image conversion model to generate an RGB image, and obtaining a defogged image. According to the processing defogging algorithm, the pixel window function is adopted when the mean value of the dark channel image is obtained, the obtained data can be more accurate, and therefore the accuracy of later image processing is further improved.

Description

technical field [0001] The present application relates to the field of image technology, in particular to an image defogging method, system, computer equipment and storage medium. Background technique [0002] With the rapid development of smart cities and security, video surveillance is everywhere in our lives. But with the aggravation of air pollution, the frequency of smog weather is getting higher and higher. In foggy weather, fine particles and water droplets suspended in the atmosphere will absorb, scatter and refract light, making the image scene generated in foggy days unclear and image details lost, limiting the use of foggy weather images and videos in traffic monitoring, Applications in areas such as target tracking and autonomous navigation. Therefore, under severe weather conditions, how to obtain high-quality clear images to achieve accurate detection of target objects is particularly important. [0003] At present, the existing image defogging methods are d...
