Underwater acoustic imaging systems are useful in providing underwater observation and inspection capabilities whenever optical systems cannot. Underwater acoustic imaging is a part of the larger field of acoustic imaging, and as such, has its own peculiarities and attributes as compared with the rest of the acoustic imaging field.

Underwater Image Rendering Survey
2023The underwater world has gained more attention in research in the last few years. This is related to ocean exploration in many industries. Images are a helpful data source for many tasks in underwater exploration but face several issues related to light behavior in this environment.

Abstract : The long-term goal of this project is to advance the state-of-the-art of underwater imaging by developing new systems that harness recent advances in laser, optical, computer processing and imaging technology. The primary application for these systems will be in imaging both natural and man-made objects in aquatic environments.

A simple underwater imaging model
Optics Letters, 2009It is commonly known that underwater imaging is hindered by both absorption and scattering by particles of various origins. However, evidence also indicates that the turbulence in natural underwater environments can cause severe image-quality degradation.

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.

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.
