Single-layer perceptron artificial visual system for orientation detection
Frontiers in Neuroscience, 2023 Orientation detection is an essential function of the visual system. In our previous works, we have proposed a new orientation detection mechanism based on local orientation-selective neurons.

Visual System: ‘S’ is not for Saccades [PDF]
Current Biology, 2002 Coloured flashes that are visible only to the short-wavelength-sensitive S cones interfere with shifts of visual attention but not with shifts of gaze (saccades). Attention and gaze must therefore be directed by different visual sub-systems.

ORB-SLAM3: An Accurate Open-Source Library for Visual, Visual–Inertial, and Multimap SLAM [PDF]
IEEE Transactions on robotics, 2020 This article presents ORB-SLAM3, the first system able to perform visual, visual-inertial and multimap SLAM with monocular, stereo and RGB-D cameras, using pin-hole and fisheye lens models.

Effect of Light Emitting Diodes (LED) Exposure on Vitreous Metabolites-Rodent Study
Metabolites, 2023 The exposure to blue and white Light emitting diodes (LED) light leads to damage in the visual system with short-term LED light exposure. Chronic exposure, adaptive responses to light, and self-protective mechanisms against LED light exposures need to be

Supporting the development and adoption of automatic lameness detection systems in dairy cattle : effect of system cost and performance on potential market shares [PDF]
, 2017 Most automatic lameness detection system prototypes have not yet been commercialized, and are hence not yet adopted in practice. Therefore, the objective of this study was to simulate the effect of detection performance (percentage missed lame cows and ...

THE VISUAL SYSTEM OF THE ALLIGATOR [PDF]
The Journal of General Physiology, 1957 The eye tissues and liver of the alligator contain vitamin A1 alone. The retina contains rhodopsin, typical in absorption spectrum (λmax 500 mµ); but synthesized in solution from neo-b retinene and opsin much more rapidly than are the frog, mammalian, or chicken rhodopsins previously examined. In this regard alligator rhodopsin resembles the rhodopsins

Computing optical flow in the primate visual system [PDF]
, 1989 Computing motion on the basis of the time-varying image intensity is a difficult problem for both artificial and biological vision systems. We show how gradient models, a well-known class of motion algorithms, can be implemented within the magnocellular ...

Asymmetric retinal direction tuning predicts optokinetic eye movements across stimulus conditions
eLife, 2023 Across species, the optokinetic reflex (OKR) stabilizes vision during self-motion. OKR occurs when ON direction-selective retinal ganglion cells (oDSGCs) detect slow, global image motion on the retina.

Emotion schemas are embedded in the human visual system
Science Advances, 2018 Human visual cortex contains distributed representations of emotion categories identified by a convolutional neural network model. Theorists have suggested that emotions are canonical responses to situations ancestrally linked to survival.
