Underwater image enhancement with image colorfulness measure [PDF]

open access: yesSignal Processing: Image Communication, 2021
Abstract Due to the absorption and scattering effects of the water, underwater images tend to suffer from many severe problems, such as low contrast, grayed out colors and blurring content. To improve the visual quality of underwater images, we proposed a novel enhancement model, which is a trainable end-to-end neural model.

Domain Adaptation for Underwater Image Enhancement via Content and Style Separation

open access: yesIEEE Access, 2022
Underwater image suffer from color cast, low contrast and hazy effect, which degraded the high-level vision application. Recent learning-based methods demonstrate astonishing performance on underwater image enhancement, however, most of these works use ...

Adaptive polarimetric image representation for contrast optimization of a polarized beacon through fog [PDF]

open access: yes, 2015
We present a contrast-maximizing optimal linear representation of polarimetric images obtained from a snapshot polarimetric camera for enhanced vision of a polarized light source in obscured weather conditions (fog, haze, cloud) over long distances ...

Real-time Model-based Image Color Correction for Underwater Robots

open access: yes, 2020
Recently, a new underwater imaging formation model presented that the coefficients related to the direct and backscatter transmission signals are dependent on the type of water, camera specifications, water depth, and imaging range.

A Survey of Restoration and Enhancement for Underwater Images

open access: yesIEEE Access, 2019
Images captured underwater usually suffer from color distortion, detail blurring, low contrast, and a bluish or greenish tone due to light scattering and absorption in the underwater medium, which in turn the visibility is adversely affected by these ...

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.

Underwater Image Enhancement using GAN

open access: yesInternational Journal of Innovative Science and Research Technology (IJISRT), 2023
The process of enhancing the distorted underwater images to clear image is known as Underwater image enhance- ment. Distorted images are the raw underwater images that taken from the deep portion of ocean, river etc by using different cameras. In general underwater images are mainly used in underwater robotics, ocean pasture and environmental monitor ...
