There are only a few more days until the SIGGRAPH 2003 show in San Diego July 29-31, 2003.  

PGR will be one of over 200 exhibitors unveiling their latest advances in the computer graphics and interactive marketplace.

Attendees can get up close and hands-on with the newest hardware and software tools in Animation, High Performance Graphics, 3D Modelling, Web 3D, Virtual Reality and many more applications.

PGR's on site demos will feature the Bumblebee® and the 3D Stereo Visualization Kit, the Dragonfly® and Dr. Fua's  face tracking application and our spherical digital video camera, the Ladybug®.  

Come visit us at booth #3425 and be one of the first to preview the soon to be released Firefly®2. 



In this issue of Insights we are featuring our Dragonfly® camera with an augmented reality application developed at the Computer Vision Laboratory at EPFL in Lausanne.

Dr. Pascal Fua and his research team have focused on developing augmented reality applications, as well as modelling of people and their motion from images and video sequences. Their research objective has been to create an augmented environment in which real and rendered scenes can be seamlessly integrated into one.

Face tracking  


At the recent Computer Vision and Pattern Recognition conference in Madison, WI, Dr. Fua's research group presented a compelling augmented reality demonstration. The demo used the Dragonfly® camera to track the position of a person's face in its full six-degrees-of-freedom. The system was able to track this position at frame rates and optionally display a virtual moustache and different styles of virtual glasses on the person's face.

"The quality of the images produced by high quality cameras, such as the Dragonfly® were key in identifying stable features on the face and accurately tracking them as the person moved," said Dr. Fua. "The PGRFlycapture library allowed easy and efficient interfacing of our algorithm with the camera."

Point Grey Research will be demonstrating this software at the upcoming Siggraph conference and exhibition. Come by our booth #3425 and try on the virtual glasses!

If you own a Dragonfly®, you can download this software at (http://cvlab.epfl.ch/software/download.html) and try it out yourself. The details of the software implementation can be found at (http://cvlab.epfl.ch/publications/vacchetti-et-al-cvpr03.pdf).
