Effects of the visual environment on object localization in posterior cortical atrophy and typical Alzheimer's disease

open access: yesFrontiers in Medicine, 2023
IntroductionVisual processing deficits in Alzheimer's disease are associated with diminished functional independence. While environmental adaptations have been proposed to promote independence, recent guidance gives limited consideration to such deficits

Multi-Scale Strengthened Directional Difference Algorithm Based on the Human Vision System

open access: yesSensors, 2022
The human visual system (HVS) mechanism has been successfully introduced into the field of infrared small target detection. However, most of the current detection algorithms based on the mechanism of the human visual system ignore the continuous ...

Where’s Wally: The influence of visual salience on referring expression generation

open access: yesFrontiers in Psychology, 2013
Referring expression generation (REG) presents the converse problem to visualsearch: Given a scene and a specified target, how does one generate adescription which would allow somebody else to quickly and accurately locatethe target?

Director field model of the primary visual cortex for contour detection. [PDF]

open access: yesPLoS ONE, 2014
We aim to build the simplest possible model capable of detecting long, noisy contours in a cluttered visual scene. For this, we model the neural dynamics in the primate primary visual cortex in terms of a continuous director field that describes the ...

Analysis and Considerations to Lessen Visual Clutter: Multidimensional Associations Between Streetscape Visual Clutter and Urban Perceptions in Shanghai

open access: yesLand
Visual clutter can affect attention, cognitive load, and environmental evaluation, yet streetscape studies often treat visual complexity as a broad construct without distinguishing visual richness from competition among visual features.

EOD Edge Sampling for Visualizing Dynamic Network via Massive Sequence View

open access: yesIEEE Access, 2018
Dynamic network visualization is crucial to understand network evolving behavior. Massive sequence view (MSV) is a classic technique for visualizing dynamic networks and provides users with a fine-grained presentation of time-varying communication trend ...

Visuomotor crowding: the resolution of grasping in cluttered scenes

open access: yesFrontiers in Behavioral Neuroscience, 2009
Reaching toward a cup of coffee while reading the newspaper becomes exceedingly difficult when other objects are nearby. Although much is known about the precision of visual perception in cluttered scenes, relatively little is understood about acting ...

Integration of the 3D Environment for UAV Onboard Visual Object Tracking

open access: yesApplied Sciences, 2020
Single visual object tracking from an unmanned aerial vehicle (UAV) poses fundamental challenges such as object occlusion, small-scale objects, background clutter, and abrupt camera motion.

COMPARING IMAGE-BASED METHODS FOR ASSESSING VISUAL CLUTTER IN GENERALIZED MAPS [PDF]

open access: yesISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2015
Map generalization abstracts and simplifies geographic information to derive maps at smaller scales. The automation of map generalization requires techniques to evaluate the global quality of a generalized map. The quality and legibility of a generalized
