My research focuses on both the alignment and compression of 3-D pointcloud data. I am also interested in recognition and segmentation of this data.

Projects:

JptView: Check out the Java OpenGL Point Cloud Viewer. It is intended to both visualize pointclouds both from Matlab and the command line, and as an interface to perform manual segmentations. The source is released under the GPL.

Costa Rica: Watch Prof. Kostas Daniilidis and me for 5min in the Discovery Channel feature "Debunked" aired June 17, 2004. As the video states, we measured how spherical these balls were.

Calib2GL: Check out the calibrated OpenGL camera simulator that I wrote for the Tele-Immersion Project.
