Deskewing of Underwater Images
IEEE Transactions on Image Processing, 2015We address the problem of restoring a static planar scene degraded by skewing effect when imaged through adynamic water surface. In particular, we investigate geometric distortions due to unidirectional cyclic waves and circular ripples,phenomena that are most prevalent in fluid flow.

An Imaging Information Estimation Network for Underwater Image Color Restoration
IEEE Journal of Oceanic Engineering, 2021Computer vision plays an important role in scientific research, resource exploration, and other underwater applications. However, it suffers from the severe color distortion, which is caused by the scattering and absorption of light in the water. In this

Design of Low-Complexity 3-D Underwater Imaging System With Sparse Planar Arrays
IEEE Transactions on Instrumentation and Measurement, 2019The development of a real-time 3-D underwater imaging system with a planar array is restricted by the huge hardware cost and computational burden associated with the large number of elements required.

Abstract : The long-term goal of this research is to advance the knowledge necessary to develop wide-swath laser-based underwater imaging systems that provide greater sensitivity over longer ranges than existing systems. In addition, since existing imaging systems are physically incompatible with small form-factor Autonomous Underwater Vehicles (AUVs),

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.

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.
