Underwater Image Enhancement Based on Adaptive Color Correction and Improved Retinex Algorithm
IEEE Access, 2023 In order to solve the problems about color distortion and low contrast of underwater images, we propose an underwater image enhancement algorithm that combines adaptive color correction with improved Retinex algorithm.

Color Balance and Fusion for Underwater Image Enhancement [PDF]
IEEE Transactions on Image Processing, 2018 We introduce an effective technique to enhance the images captured underwater and degraded due to the medium scattering and absorption. Our method is a single image approach that does not require specialized hardware or knowledge about the underwater conditions or scene structure. It builds on the blending of two images that are directly derived from a

Uncertainty Inspired Underwater Image Enhancement
, 2022 A main challenge faced in the deep learning-based Underwater Image Enhancement (UIE) is that the ground truth high-quality image is unavailable. Most of the existing methods first generate approximate reference maps and then train an enhancement network with certainty. This kind of method fails to handle the ambiguity of the reference map.
