Coliseum is a multiuser immersive remote teleconferencing system designed to provide collaborative workers the experience of face-to-face meetings from their desktops. Five cameras are attached to each PC display and directed at the participant. From these video streams, view synthesis methods produce arbitrary-perspective renderings of the participant and(More)
telepresence, teleconferencing, view synthesis We describe Coliseum, a desktop system for immersive teleconferencing. Five cameras attached to a desktop LCD monitor are directed at a participant. View synthesis methods produce arbitrary-perspective renderings of the participant from these video streams, and transmit them to other participants. Combining(More)
volume rendering, compositing, ray tracing Volume rendering creates images from sampled volumetric data. The compute intensive nature of volume rendering has driven research in algorithm optimization. An important speed optimization is the use of preclassification and preshading. We demonstrate an artifact that results when interpolating from preclassified(More)

The particle-system technique is used to model 'fuzzy objects', i.e. objects not bounded by well-defined, easily visible surfaces. the technique is used to depict, in real time, ship wakes in an air/sea simulation using a high-speed workstation for graphics calculation and display. The system consists of a graphics workstation tied to a compute server(More)
We are currently developing an Automatic Target Recognition (ATR) algorithm to locate an object using multi-sensor data. The ATR algorithm will determine corresponding points between a range (LADAR) image, a color (CCD) image, a thermal (FLIR) image and a BRL/CAD model of the object being located. The success of this process depends in part on which(More)
The Rangeview software system presented here addresses two significant issues in the development and deployment of an Automatic Target Recognizer: visualization of progress of the recognizer in finding a target, and verification by an operator of the correctness of the match. The system combines range imagery from a LADAR device with optical imagery from a(More)
