Underwater Image Enhancement Based on Adaptive Color Correction and Improved Retinex Algorithm

open access: yesIEEE 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.

Multiscale Fusion for Underwater Image Enhancement

open access: yesInternational Journal of Emerging Research in Engineering, Science, and Management, 2022
In this paper, an enhancement scheme on underwater images is proposed. Underwater images undergo efforts like scattering and attenuation. Many techniques are proposed for underwater image and enhancement that largely depends on the features and ...

Fine reconstruction of underwater images for environmental feature fusion

open access: yesInternational Journal of Advanced Robotic Systems, 2021
Complicated underwater environments, such as occlusion by foreign objects and dim light, causes serious loss of underwater targets feature. Furthermore, underwater ripples cause target deformation, which greatly increases the difficulty of feature ...

A new 3-D modelling method to extract subtransect dimensions from underwater videos [PDF]

open access: yes, 2012
Underwater video transects have become a common tool for quantitative analysis of the seafloor. However a major difficulty remains in the accurate determination of the area surveyed as underwater navigation can be unreliable and image scaling does not ...

Enhancing underwater images by fusion [PDF]

open access: yesACM SIGGRAPH 2011 Posters, 2011
When photographs are taken in underwater conditions the visibility of the scene is degraded significantly. This is due to the fact that the radiance of a point in the scene is directly influenced by the medium scattering. Practically, distant objects and part of the scene suffers from poor visibility, loss of contrast and faded colors.

UMGAN: Underwater Image Enhancement Network for Unpaired Image-to-Image Translation

open access: yesJournal of Marine Science and Engineering, 2023
Due to light absorption and scattering underwater images suffer from low contrast, color distortion, blurred details, and uneven illumination, which affect underwater vision tasks and research.
