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 An Integrated Colour Model. [PDF]

open access: yes, 2007
In underwater situations, clarity of images are degraded by light absorption and scattering. This causes one colour to dominate the image.

Delaunay triangulation based image enhancement for echocardiography images [PDF]

open access: yes, 2009
A novel image enhancement approach for automatic echocardiography image processing is proposed. The main steps include undecimated wavelet based speckle noise reduction, edge detection, followed by a regional enhancement process that employs Delaunay ...

A potential-flow based flight simulator for an underwater glider [PDF]

open access: yes, 2013
Underwater gliders are recent innovative types of autonomous underwater vehicles (AUVs) used in ocean exploration and observation. They adjust their buoyancy to dive and to return to the ocean surface.

A Non-Reference Evaluation of Underwater Image Enhancement Methods Using a New Underwater Image Dataset

open access: yesIEEE Access, 2023
The rise of vision-based environmental, marine, and oceanic exploration research highlights the need for supporting underwater image enhancement techniques to help mitigate water effects on images such as blurriness, low color contrast, and poor quality.

Literature Survey on Underwater Image Enhancement

open access: yes, 2020
Underwater image enhancement is a challenging task and has gained priority in recent years, as the human eye cannot clearly perceive underwater images. We introduce an effective technique to develop the images captured underwater which are degraded due ...

Is Underwater Image Enhancement All Object Detectors Need? [PDF]

open access: yes, 2023
Underwater object detection is a crucial and challenging problem in marine engineering and aquatic robot. The difficulty is partly because of the degradation of underwater images caused by light selective absorption and scattering. Intuitively, enhancing

DuGAN: An effective framework for underwater image enhancement [PDF]

open access: yesIET Image Processing, 2021
Abstract Underwater image enhancement is an important low‐level vision task with much attention of community. Clear underwater images are helpful for underwater operations. However, raw underwater images often suffer from different types of distortions caused by the underwater environment.

Image resolution enhancement using dual-tree complex wavelet transform [PDF]

open access: yes, 2010
In this letter, a complex wavelet-domain image resolution enhancement algorithm based on the estimation of wavelet coefficients is proposed. The method uses a forward and inverse dual-tree complex wavelet transform (DT-CWT) to construct a high-resolution

An Underwater Image Enhancement Algorithm Based on MSR Parameter Optimization

open access: yesJournal of Marine Science and Engineering, 2020
The quality of underwater images is often affected by the absorption of light and the scattering and diffusion of floating objects. Therefore, underwater image enhancement algorithms have been widely studied. In this area, algorithms based on Multi-Scale
