Uncertainty Inspired Underwater Image Enhancement [PDF]
European Conference on Computer Vision, 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 ...
