Spaceborne underwater imaging [PDF]
2011 IEEE International Conference on Computational Photography (ICCP), 2011 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 ...

Fast Underwater Image Enhancement for Improved Visual Perception [PDF]
IEEE Robotics and Automation Letters, 2019 In this letter, we present a conditional generative adversarial network-based model for real-time underwater image enhancement. To supervise the adversarial training, we formulate an objective function that evaluates the perceptual image quality based on

Polish Hyperbaric Research, 2021 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 computational ghost imaging
Optics Express, 2017 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 ...
