Underwater Image Restoration Based on Image Blurriness and Light Absorption [PDF]

open access: yesIEEE Transactions on Image Processing, 2017
Underwater images often suffer from color distortion and low contrast, because light is scattered and absorbed when traveling through water. Such images with different color tones can be shot in various lighting conditions, making restoration and ...

Underwater image restoration via Stokes decomposition

Optics Letters, 2022
In this Letter, we present a Stokes imaging-based method to restore objects and enhance image contrast in turbid water. In the system, a light source illuminates the objects with two orthometric polarization states; based on a new Stokes decomposition model, the recorded images are converted to Stokes maps and subsequently restored to a clear image ...

Fusion-based restoration of the underwater images

2011 18th IEEE International Conference on Image Processing, 2011
In this paper we introduce a novel strategy that effectively enhance the visibility of underwater images. Our method is build-up on the fusion strategy that takes a sequence of inputs derived from the initial image. Practically, our fusion-based method aims to yield a final image that overcomes the deficiencies existing in the degraded input images by ...

Fusion of Underwater Image Enhancement and Restoration

International Journal of Pattern Recognition and Artificial Intelligence, 2019
Optical properties of water distort the quality of underwater images. Underwater images are characterized by poor contrast, color cast, noise and haze. These images need to be pre-processed so as to get some information. In this paper, a novel technique named Fusion of Underwater Image Enhancement and Restoration (FUIER) has been proposed which ...

A Rapid Scene Depth Estimation Model Based on Underwater Light Attenuation Prior for Underwater Image Restoration

open access: yesLecture Notes in Computer Science, 2018
Underwater images present blur and color cast, caused by light absorption and scattering in water medium. To restore underwater images through image formation model (IFM), the scene depth map is very important for the estimation of the transmission map ...

A simple and comprehensive model for underwater image restoration

2013 IEEE International Conference on Information and Automation (ICIA), 2013
Light is absorbed and scattered by water when propagating underwater. Image quality of underwater objects is extremely contaminated and degenerated by the factors of backscatter and attenuation. So underwater images should be restored to recover the useful information.

Underwater image restoration

2018
Underwater imaging has been widely used as a tool in many fields, however, a major issue is the quality of the resulting images/videos. Due to the light's interaction with water and its constituents, the acquired underwater images/videos often suffer from a significant amount of scatter (blur, haze) and noise.

Review on underwater image restoration and enhancement algorithms

Proceedings of the 7th International Conference on Internet Multimedia Computing and Service, 2015
The serious degradation of underwater image is the result of light scattering by particles, and light absorption causes the color attenuation. Thus, the task of underwater enhancement is improving the visibility and restoring the color by removing undesirable effect during the process of imaging.

Underwater image restoration based on contrast enhancement

2016 IEEE International Conference on Digital Signal Processing (DSP), 2016
Low contrast and color distortion are two major problems suffered by underwater images. In this work, a novel and systematic enhancement method based on contrast enhancement is proposed to restore the degraded underwater images. The proposed method mainly contains three steps.

Estimation-based approach for underwater image restoration

Optics Letters, 2011
For underwater image restoration, modeling of PSF relies on a priori knowledge of the inherent optical properties under water. But full knowledge-based restoration could be corrupted by the complexity and instability of the application environments. Concerned with representation of the backscattering noise of underwater image, this Letter proposes a ...
