Detection and recognition of visual targets

Journal of the Optical Society of America A, 1985
To aid the development of detection-based interpretations of visual resolution, we evaluated theorems that (1) relate observers' performance in detection of a single target to that in 1-of-m signal detection and (2) predict recognition performance from measured performance at 1-of-m detection.

Detecting Visual Field Progression

Ophthalmology, 2017
Timely detection of glaucomatous progression is crucial in the delivery of glaucoma care. Clinical judgment may be used to make this assessment, but relatively modest agreement among practitioners supports the use of complementary methods. Event-based analyses take into account expected localized test-retest variabilities in sensitivity, and trend ...

Hierarchical Visual Relationship Detection

Proceedings of the 27th ACM International Conference on Multimedia, 2019
Acting as a bridge between vision and language, visual relationship detection (VRD) aims to represent objects and their interactions in an image with several relationship triplets. Nevertheless, the conventional VRD task shows little consideration for the penalization of incorrect relationship predictions, which in turn undermines its support for image

Visualizing clone detection results

Proceedings of the twenty-second IEEE/ACM international conference on Automated software engineering, 2007
It has been observed by many practitioners that software applications frequently contain redundant code fragments. This redundancy is often caused by the common programming practice of replicating (or cloning) existing code and then customizing code fragments to handle new demands within an application.

Acoustic facilitation of visual detection.

Journal of Experimental Psychology, 1965
Abstract : Eleven Os were required to judge which of 4 temporal intervals contained a visual signal, in an experiment involving a total of 10,900 trials. Under some conditions, potentially useful time information was conveyed by accompanying sound stimulation, while it was lacking under others. Highest detectability of the signal was associated with an

A Visual Solution in Asteroids Detection

2019 21st International Symposium on Symbolic and Numeric Algorithms for Scientific Computing (SYNASC), 2019
Asteroid discovery is not an activity restricted to the notable surveying efforts that have their private staff, equipment and detection programs, but it is also popular among amateurs and various mini-surveys. In light of this situation, new Near Earth Asteroids (NEAs) are found out every day.

Activity Detection for scientific visualization

2011 IEEE Symposium on Large Data Analysis and Visualization, 2011
Understanding the science behind ultra-scale simulations requires extracting meaning from data sets of hundreds of terabytes or more. At extreme scales, the data sets are so huge, there is not even enough time to view the data, let alone explore it with basic visualization methods.

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 ...

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 ...
