Target acquisition methodology for visual and infrared imaging sensors
TL;DR: A comprehensive analysis of each method and a detailed comparison of these different methodologies shows that they are in remarkably good agreement throughout their ranges of applicabil- ity.
Journal ArticleDOI
Detection probability using relative clutter in infrared images
TL;DR: In this article, a new clutter metric, called relative clutter, based on factor analysis, was developed for human-in-the-loop target acquisition, which combines many definitions of clutter.
Research article SAFER under vehicle inspection through video mosaic building
TL;DR: In this article, the authors describe efforts made to build multi-perspective mosaics of infrared and color video data for the purpose of under vehicle inspection, which is desired to create a large, high-resolution mosaic that may be used to quickly visualize the entire scene shot by a camera making a single pass underneath the vehicle.
