• 3D Computer Vision Group - We are developing techniques for representing, comparing, and matching general, free-form surfaces.
• Vision and Mobile Robotics Lab - Our group studies fundamental problems of Computer Vision and ground mobile robotics.

• 3D Object Recognition - We are applying our techniques for surface representation and matching to object recognition problems; for example, we have used 3D object recognition as part of the Artisan system for interior mapping.
• Sonar Mapping for Underwater Vehicles - Elevation map refinement from bathymetric side-scan sonar images
