Spaceborne underwater imaging [PDF]
Shallow waters are very important for human and biological activity. Remote sensing of these areas is challenging, as it requires separation of ocean (or lake) bottom, water and atmospheric effects. In this paper we describe a concept and theory for spaceborne recovery of the underwater depth map, optical characteristics of the water and atmosphere ...

Abstract Attenuation of light in the ocean ranges widely depending on the environment and is especially significant in optical remote sensing. Absorption of light by ocean water limits the range light can travel before being extinguished. The complex interactions of scattering light and ocean water often lead to distortions of the signal

Underwater Color-Cast Image Enhancement by Noise Suppression and Block Effect Elimination
Efficient underwater visual environment perception is the key to realizing the autonomous operation of underwater robots. Because of the complex and diverse underwater environment, the underwater images not only have different degrees of color cast but ...

Underwater computational ghost imaging
Since the quality of underwater classical optical imaging is constrained by the absorptive and scattering nature for underwater environment, it is a challenging task to obtain long distance imaging. Ghost imaging is a second-order correlation imaging method using co-incidence measurement, which has the advantages of disturbance-free and wider angle of ...

The Synthesis of Unpaired Underwater Images Using a Multistyle Generative Adversarial Network
Underwater image datasets are crucial in underwater vision research. Because of the strong absorption and scattering effects that occur underwater, some ground truth such as the depth map, which can be easily collected in-air, becomes a great challenge ...

A low-cost hyperspectral scanner for natural imaging and the study of animal colour vision above and under water [PDF]
Hyperspectral imaging is a widely used technology for industrial and scientific purposes, but the high cost and large size of commercial setups have made them impractical for most basic research.
