Kostas Daniilidis

Associate Professor, CIS

Research Interests

My research focuses on the basic questions of space and motion perception with machines and how we can use resulting algorithms to create visually compelling immersive environments.

• Geometry and signal analysis of omnidirectional vision
• Scene acquisition for tele-immersion
• Registration in mixed realities

Current Projects

• Digital Archeology
• Geometry of omnidirectional vision
• Multi-robot Emergency Response
• Tele-immersion creates the illusion of sharing the same space though you might be thousands of miles apart. (view image)
• Signal processing in non conventional images
