Fast Underwater Image Enhancement for Improved Visual Perception [PDF]

open access: yesIEEE 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

The visual perception of motion [PDF]

open access: yesCurrent Biology, 2004
Sensing the movements of the world and the objects within it appears to be a fundamental job for our visual system. In rare cases of brain damage, we find that individuals lacking motion perception live in a very different world of frozen images, where simple tasks like filling a kettle or crossing the road take on alarming difficulties.

Dynamics of Visual Adaptation With Simultaneous Stimulation of Two Visual Pathways

open access: yesFrontiers in Neuroscience, 2021
Primates’ retinal ganglion cells in different visual pathways have been shown to adapt independently (Current Biology 22 (2012) 220–224). However, the manner in which adaptation occurs under simultaneous stimulation of two visual pathways has not yet ...
