For years, panoramic image stitching has been an interesting problem for re- searchers. Several advances have been made in stitching images that are ac- quired outside of water, but the problem has been poorly explored for under- water images. Image stitching for underwater images can be used in numerous scientific applications in the fields of marine ...

Underwater polarization imaging technology
2009 Conference on Lasers & Electro Optics & The Pacific Rim Conference on Lasers and Electro-Optics, 2009Polarimetric imaging can be used to remove degradation effects in underwater vision, and can be applied to high-level vision tasks, such as object classification and recognition and camouflage identification. Polarimetry and Characterization technique were introduced in detail.

One of the main issues concerning diver visibility is that it is directly dependent on the availability of natural light. The theories developed and discussed in the last chapter, for the most part, are only applicable under ideal situations. In other words, they can be seen as a one-way propagation special case, where path radiance can be neglected or

Digital image processing of underwater images
2006 IEEE US/EU Baltic International Symposium, 2006We describe the motivation and some preliminary results of a long term project to monitor a coral reef using computer vision. We show the calculation of a background image of coral without fish by median filtering of an image sequence. We illustrate the extraction of fish from images and show that a texture can pair examples of fish species from ...

Underwater Imaging Gets Clearer
Optics and Photonics News, 2013Underwater imaging in natural bodies of water is notoriously difficult due to the large range of particulates that can impede light propagation. However, recent developments in optical technology that build on polarization-based encryption and lidar are leading to incremental advances.

IEEE transactions on circuits and systems for video technology (Print)
Underwater imaging grapples with challenges from light-water interactions, leading to color distortions and reduced clarity. In response to these challenges, we propose a novel Color Balance Prior Guided Hybrid Sense Underwater Image Restoration ...

Underwater Image Systems Simulation
Imaging and Applied Optics 2017 (3D, AIO, COSI, IS, MATH, pcAOP), 2017We use modern computer graphics tools such as ray-tracing, digital camera simulation tools, and a physically accurate model of seawater constituents to simulate how light is captured by the imaging sensor in a digital camera placed in underwater ocean environments.

Imaging Underwater for Archaeology
Journal of Field Archaeology, 2000In this paper we examine underwater imaging for archaeology and especially the use of multiple acoustic and optical sensors at varying degrees of resolution for reconnaissance and mapping sites on the seafloor. Specifically, we look at the role of side-scan sonar for locating suitable sites of interest, which may then be mapped quantitatively with ...

Underwater Image Color Correction using Exposure-Bracketing Imaging
IEEE Signal Processing Letters, 2018Absorption and scattering of light in an underwater scene saliently attenuate red spectrum components. They cause heavy color distortions in the captured underwater images.

Non-Uniform Illumination Underwater Image Restoration via Illumination Channel Sparsity Prior
IEEE transactions on circuits and systems for video technology (Print)Underwater image quality is seriously degraded due to the insufficient light in water. Although artificial illumination can assist imaging, it often brings non-uniform illumination phenomenon.
