Underwater Image Enhancement via Medium Transmission-Guided Multi-Color Space Embedding [PDF]
IEEE Transactions on Image Processing, 2021 Underwater images suffer from color casts and low contrast due to wavelength- and distance-dependent attenuation and scattering. To solve these two degradation issues, we present an underwater image enhancement network via medium transmission-guided ...

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 ...
