Underwater Image Enhancement by Fusion
2018Underwater images are suffered by several factors like color absorption, light scattering, and these lead to poor visibility and low contrast of an underwater image. Typical image restoration methods rely on the popular Dark Channel Prior. However, the result of the underwater image which has only been dealt with the restoration algorithm is still not ...

Bayesian retinex underwater image enhancement
Engineering Applications of Artificial Intelligence, 2021Abstract This paper develops a Bayesian retinex algorithm for enhancing single underwater image with multiorder gradient priors of reflectance and illumination. First, a simple yet effective color correction approach is adopted to remove color casts and recover naturalness.

Adaptive Enhancement of Underwater Images
2013Underwater images usually suffer from low contrast and non-uniform lightning. To overcome this histogram equalization is the basic technique for enhancement due to its simple function and effectiveness. This method tends to change the brightness of an image and therefore, not suitable for consumer electronic products, where preserving the original ...

QUALITATIVE ANALYSIS OF UNDERWATER IMAGE ENHANCEMENT
2021 5th International Conference on Trends in Electronics and Informatics (ICOEI), 2021In underwater imaging, the visual quality of both video and image is degraded, influencing the recognition of many marine resources. Backscattering and attenuation are the main reasons in degradation of quality in underwater images. This paper aims at study and comparison of recent algorithms used to improve the visual quality of underwater images ...

Underwater Image Enhancement for Automotive Wading
2021 13th International Conference on Computer and Automation Engineering (ICCAE), 2021To improve the driver safety for automotive wading, the underwater image enhancement is designed to help drivers to deal with fuzzy images shown in highly scattered underwater environments and detect hidden obstacles. In addition to the traditional methods, some neural network approaches which may perform better are suggested. The purpose of this paper

Enhancing underwater images and videos by fusion
2012 IEEE Conference on Computer Vision and Pattern Recognition, 2012This paper describes a novel strategy to enhance underwater videos and images. Built on the fusion principles, our strategy derives the inputs and the weight measures only from the degraded version of the image. In order to overcome the limitations of the underwater medium we define two inputs that represent color corrected and contrast enhanced ...

Image Enhancement and Restoration Methods for Underwater Images
2014In this chapter, the authors provide an overview of state-of-the-art image enhancement and restoration techniques for underwater images. Underwater imaging is one of the challenging tasks in the field of image processing and computer vision. Usually, underwater images suffer from non-uniform lighting, low contrast, diminished color, and blurring due to

Visual Enhancement Techniques For Underwater Images
2019 5th International Conference on Advanced Computing & Communication Systems (ICACCS), 2019In the recent days, wide range of research has been carried out on visual enhancement of under images in submarine and military operations to discover submerged structural designing and sea floor exploration. But, diving in the deep ocean for a long time has increased the difficulties for analysis of underwater images.

Fusion of Underwater Image Enhancement and Restoration
International Journal of Pattern Recognition and Artificial Intelligence, 2019Optical 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 ...

Enhancement and Restoration of Underwater Images
The aim of exploring the deep undersea world map, a picture of high quality without interfering objects is preferred. However, within the water, the image quality tends to be hampered by light scattering, water density, and light attenuation. effects. Besides, the dynamic interference may affect the important underwater map.openaire +1 more source
