Attentive Wide-Field Sensing for Visual Telepresence and Surveillance [chapter]

James H. Elder, Fadi Dornaika, Bob Hou, Ronen Goldstein
2005 Neurobiology of Attention  
These prototype sensors serve as useful testbeds for computational models of visual attention, and may lead to new telepresence and surveillance technologies.  ...  An attentive component provides a much smaller, shiftable FOV at high resolution, designed to recognize and interpret events detected by the pre-attentive system.  ...  For example, in a remote surveillance system monitored by a human security specialist, pre-attentive and attentive visual data could be displayed on separate monitors.  ...

A Self-Referential Perceptual Inference Framework for Video Interpretation [chapter]

Christopher Town, David Sinclair
2003 Lecture Notes in Computer Science  
Perceptual inference then takes place within an ontological domain defined by the structure of the problem and the current goal set.  ...  This representation allows one to pose the problem of video analysis in terms of queries expressed in a visual language incorporating prior hierarchical knowledge of the syntactic and semantic structure  ...  Visual search guided by a query posed in a language embodying an ontological representation of a domain allows adaptive processing strategies to be utilised and gives an effective attentional control mechanism  ...
