Problems solved by technology

The disadvantage of this algorithm is that it is more complicated, and at the same time, it has not achieved good results.
At present, some related studies have proposed a neural network-based underwater image defogging method, which has achieved good results, but there are still problems such as insufficient defogging, distorted results, or loss of edge information.

Abstract

The invention relates to an underwater image processing system and method with edge retention. The system comprises: a transmission map estimation module configured to perform a transmission map recovery operation on an acquired degraded underwater image to generate a transmission map estimation of the underwater image; an ambient light estimation module configured to perform an ambient light estimation operation on the underwater image to generate an ambient light estimation of the underwater image; a defogging processing module configured to perform defogging processing on the underwater image based on the transmission image estimation and the ambient light estimation to obtain a defogged underwater image; and a discriminator module configured to discriminate the transmission map estimation and the defogged underwater image from a transmission map true value and a defogged underwater image true value, and train and supervise the transmission map estimation and the ambient light estimation based on a discrimination result.

Description

technical field [0001] This application relates to the field of image processing, and in particular to the technology of using generative adversarial networks to realize underwater image processing with edge preservation. Background technique [0002] With the development of image technology, more and more underwater operations begin to use vision systems to collect underwater image or video data, and analyze the collected data automatically through human observation or with the help of computers. However, because light is affected by attenuation and scattering when it propagates in water, and different wavelengths of light are affected to different degrees, the quality of underwater images is damaged and the color is deviated, which affects computer vision such as target detection and target tracking. performance of the algorithm. Therefore, it is of great significance to enhance underwater images. Since the enhancement of underwater images is similar to the removal of fog...
