Visual examination apparatus [PDF]
, 1976 An automated visual examination apparatus for measuring visual sensitivity and mapping blind spot location including a projection system for displaying to a patient a series of visual stimuli. A response switch enables him to indicate his reaction to the

Parallel Adaptation to Spatially Distinct Distortions
Frontiers in Psychology, 2020 Optical distortions as a visual disturbance are inherent in many optical devices such as spectacles or virtual reality headsets. In such devices, distortions vary spatially across the visual field.

A model of amacrine cells for orientation detection
Electronic Research Archive, 2023 As the most studied sensory system, the visual system plays an important role in our understanding of brain functions. Biological researchers have divided the nerve cells in the retina into dozens of visual channels carrying various characteristics based

THE PORPHYROPSIN VISUAL SYSTEM [PDF]
Journal of General Physiology, 1939 1. In the rods of fresh-water and some anadromous fishes, rhodopsin is replaced by the purple photolabile pigment porphyropsin. This participates in a retinal cycle identical in form with that of rhodopsin, but in which new carotenoids replace retinene and vitamin A. 2. Porphyropsin possesses a broad absorption maximum at 522 ± 2 mµ, and

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.

FEBS Letters, EarlyView.Cells must clear mislocalized or faulty proteins from membranes to survive. The AAA+ ATPase Msp1 performs this task, but dissecting how its six subunits work together is challenging. We engineered linked dimers with varied numbers of functional subunits to reveal how Msp1 subunits cooperate and use energy to extract proteins from the lipid bilayer ...

Grounding semantics in robots for Visual Question Answering [PDF]
, 2019 In this thesis I describe an operational implementation of an object detection and description system that incorporates in an end-to-end Visual Question Answering system and evaluated it on two visual question answering datasets for compositional ...

FEBS Letters, EarlyView.Phototrophs evolved light‐harvesting systems adapted for efficient photon capture in habitats enriched in far‐red radiation. A subset of eukaryotic pigment‐binding proteins can absorb far‐red photons via low‐energy chlorophyll states known as red forms.

Human mobility monitoring in very low resolution visual sensor network [PDF]
, 2014 This paper proposes an automated system for monitoring mobility patterns using a network of very low resolution visual sensors (30 30 pixels). The use of very low resolution sensors reduces privacy concern, cost, computation requirement and power ...
