Multi-module cascaded underwater image enhancement method

Abstract

The invention provides a multi-module cascaded underwater image enhancement method, and belongs to the technical field of computer vision. The method comprises the steps that an existing air image enhancement network and a color correction network are cascaded, a multi-module cascaded enhancement network is constructed, the air image enhancement network is used for solving the degradation problem similar to that of an air image in an underwater image, and the color correction network is used for correcting color cast existing in the underwater image; obtaining a paired underwater image data set, and training the multi-module cascade enhancement network by using the obtained paired underwater image data set; and obtaining a to-be-enhanced underwater image, and sending the to-be-enhanced underwater image to the trained multi-module cascade enhancement network to obtain an enhanced underwater image. According to the invention, different types of degradation problems in underwater imaging can be solved.

Description

technical field [0001] The invention relates to the technical field of computer vision, in particular to a multi-module cascaded underwater image enhancement method. Background technique [0002] In recent years, as a key issue in image enhancement research, underwater image enhancement has attracted more and more researchers' attention. As an important carrier of marine information, underwater images play a vital role in our exploration of the marine environment and the rational development and utilization of marine resources. However, due to the complexity of the underwater imaging environment, the obtained underwater images are often accompanied by degradation problems such as blurring, low contrast, color distortion, and poor visibility, which seriously affect the performance of underwater vision-based tasks. Therefore, improving the quality of underwater images is urgently needed. [0003] In the past decades, many methods have been proposed to improve the quality of ...
