Visual detection of distant objects

Proceedings of 1993 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS '93), 2002
Taking an autonomous road vehicle as an example, approaches and methods for object detection (this being the first step of obstacle recognition) are discussed. Vision, using a single passive camera as the primary sensor and a real-time vision system for analyzing the resulting image sequence, is found to be the best approach.

Visual Motion Detection in the Cat

Science, 1964
Responses of some cells in the cat cortex to moving stimulation depend on direction of motion. These cells give neither "on" nor "off" responses to uniform illumination. Response can be elicited over a wide region of the retina in either eye, and the discharge pattern does not follow the temporal variations in luminance on the retina which accompany ...

Visualization of clone detection results

Proceedings of the 2006 OOPSLA workshop on eclipse technology eXchange - eclipse '06, 2006
The goal of a clone detection tool is to identify sections of code that are duplicated in a program. The result of the detection is presented in some manner for the user to view, which is usually in the form of a list of clones that are grouped together.

Clinical Visual Caries Detection

2009
The reliable and reproducible detection of dental caries by clinical examination has been recognized as a problem for decades with very variable approaches being taken to recognize and stage lesions along the continuum of caries--from very small initial lesions, just visible to the human eye, through more established white- and brown-spot lesions, to ...

A model of visual threshold detection

Journal of Theoretical Biology, 1977
Abstract A model of visual incremental threshold detection is presented, having the following features. 1. (1) From Crozier's Law we deduce that all thresholds, for conventional as well as for noisy images, are ultimately determined by noise. Other evidence, which is described, supports this conclusion. 2.

Mechanisms of visual motion detection

Nature Neuroscience, 2000
Visual motion is processed by neurons in primary visual cortex that are sensitive to spatial orientation and speed. Many models of local velocity computation are based on a second stage that pools the outputs of first-stage neurons selective for different orientations, but the nature of this pooling remains controversial.

Visual marking and change detection

Cognitive Processing, 2007
The preview benefit from prior exposure of response-irrelevant (distracter) objects in visual search has been accounted for in terms of top-down inhibition (i.e. visual marking), bottom-up abrupt onset capture, or asynchrony-dependent perceptual segregation.

Video Visual Relation Detection

Proceedings of the 25th ACM international conference on Multimedia, 2017
As a bridge to connect vision and language, visual relations between objects in the form of relation triplet $langle subject,predicate,object\rangle$, such as "person-touch-dog'' and "cat-above-sofa'', provide a more comprehensive visual content understanding beyond objects.

A Visual Grammar for Face Detection

2010
Several methods have been developed for face detection with certain success, however these tend to fail under difficult conditions such as partial occlusions and changes in orientation and illumination. We propose a novel technique for face detection based on a visual grammar.
