Advanced underwater image restoration in complex illumination conditions

ISPRS Journal of Photogrammetry and Remote Sensing
Underwater image restoration has been a challenging problem for decades since the advent of underwater photography. Most solutions focus on shallow water scenarios, where the scene is uniformly illuminated by the sunlight. However, the vast majority of uncharted underwater terrain is located beyond 200 meters depth where natural light is scarce and ...

Underwater Image Enhancement Based on Light Field-Guided Rendering Network

Journal of Marine Science and Engineering
Underwater images often encounter challenges such as attenuation, color distortion, and noise caused by artificial lighting sources. These imperfections not only degrade image quality but also impose constraints on related application tasks.

Osmosis: RGBD Diffusion Prior for Underwater Image Restoration

Underwater image restoration is a challenging task because of water effects that increase dramatically with distance. This is worsened by lack of ground truth data of clean scenes without water. Diffusion priors have emerged as strong image restoration priors.

Feature Complementarity-Guided Multi-Weight Multi-Scale Fusion Framework for Underwater Image Enhancement

Applied Sciences
The selective wavelength absorption and scattering effects caused by complex underwater optical environments lead to a significant contradiction between color restoration and structural preservation in image enhancement. To break through this bottleneck,
