We introduce the publicly available Open Development for Video Surveillance (ODViS) system that is specifically designed to support ongoing research in tracking and video surveillance. The system provides researchers with the ability to prototype tracking and event recognition techniques, to construct and manage ground truth data sets, and to evaluate the(More)
To evaluate the neural regulation of postprandial somatostatin release we studied the effect of blockade of (a) alpha-adrenergic and beta-adrenergic and (b) cholinergic receptors on the plasma somatostatin, gastrin and insulin responses to a standard meal in two groups of five fasting healthy male volunteers. Thymoxamine (0.1 mg/kg iv over two minutes then(More)
Front-projection display environments suffer from a fundamental problem: users and other objects in the environment can easily and inadvertently block projectors, creating shadows on the displayed image. We introduce a technique that detects and corrects transient shadows in a multi-projector display. Our approach is to minimize the difference between(More)
Imagine visiting a museum and being asked to view the latest exhibit through a 20-inch window. Museum curators will gladly maneuver items to any position you ask, but visualization is always limited to the window. Such is the current state of digital libraries. Digital libraries house media of ever-increasing complexity, from models of statues to virtual(More)
Front-projection displays are a cost-effective and increasingly popular method for large format visualization and immersive rendering of virtual models. New approaches to projector tiling, automatic calibration, and color balancing have made multiprojector display systems feasible without undue infrastructure changes and maintenance. As a result,(More)
Concentrations of radionuclides were measured in soils from a grid of locations surrounding the US Department of Energy Waste Isolation Pilot Plant (WIPP) in southeastern New Mexico and from a grid on a reference site approximately 20 km southeast of the WIPP site. Each of the two grids has 16 sampling locations (grid nodes) systematically distributed(More)
Foliar absorption of resuspended 90Sr, root uptake and contamination adhering to leaf surfaces (i.e. soil loading) were compared at two Chernobyl-contaminated sites, Chistogalovka and Polesskoye. Although foliar absorption of resuspended 90Sr was quantifiable, its contribution amounted to less than 10% of the plants' total, above-ground contamination. Root(More)
Front-projection display systems suffer from a fundamental problem: the user can easily and inadvertently block the projector, creating shadows. The framework we present in this paper enables a front-projected display system to solve this problem and remove display surface shadows in real-time. Shadows are an example of radiometric inconsistencies, which(More)
