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

PLoS 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

Land
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

IEEE 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

Frontiers 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

Applied 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]

ISPRS 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

Clutter costs in head-mounted displays: a study examining trade-offs between overlay and adjacent presentation of information

Cognitive Research
This work examines the influence of clutter when presenting information with a head-mounted display (HMD). We compare clutter costs when displays overlay a real-world scene to the costs of visual scanning required when displays are presented separately ...

Optimization of Visual Information Presentation for Visual Prosthesis

International Journal of Biomedical Imaging, 2018
Visual prosthesis applying electrical stimulation to restore visual function for the blind has promising prospects. However, due to the low resolution, limited visual field, and the low dynamic range of the visual perception, huge loss of information ...
