Abstract

The invention relates to the technical field of image enhancement, in particular to a multi-branch underwater image enhancement system for non-uniform illumination and color distortion, and the system comprises a data set which is used for storing underwater images and carrying out model training and testing; the brightness correction module is used for receiving the original image, converting the original image into an L channel of a CIELab color space, further decomposing the L channel into a reflection component R and an illumination component I based on a Retinex theory, performing brightness correction by adopting a double encoder-decoder structure, and outputting an image P after brightness correction; based on a global-local feature double-branch underwater image enhancement model GLNet, receiving an image P, respectively processing color feature and contrast feature related information by adopting a double-branch network from global features and local features, and comprehensively repairing three levels of brightness, contrast and color of an underwater image to realize image enhancement.
