Registering Real and Virtual Imagery

Registering a virtual scene with a real scene captured by a video camera has a number of applications including visually-guided robotic navigation, surveillance, military training and operation. The fundamental problem involves several challenging research issues including finding corresponding points between the virtual and the real scene and camera calibration. This paper presents our researc...

Real-time Music Visualization Using Responsive Imagery

We present a music visualization system that allows musical feature data to be extracted in real-time from live performance and mapped to responsive imagery. We have created three example mappings between music and imagery, illustrating how music can be visualized through responsive video, virtual character behaviour, and interactive features inside an immersive virtual space. The system is imp...

Real-Time Object Recognition in Color Imagery

Military test ranges containing unexploded ordnance due to live-fire testing and training exercises are a significant safety problem in many locations. Automated cleanup of such sites is a challenging goal. Towards this end, this paper describes algorithms to detect a type of ordnance in current usage using color imagery. The techniques are designed to run in realtime using off-the-shelf hardwa...

Near Real-Time Browsable Landsat-8 Imagery

The successful launch and operation of Landsat-8 extends the remarkable 40-year acquisition of space-based land remote-sensing data. To respond quickly to emergency needs, real-time data are directly downlinked to 17 ground stations across the world on a routine basis. With a size of approximately 1 Gb per scene, however, the standard level-1 product provided by these stations is not able to se...
