Computer Science Professor Shree Nayar to Deliver University Lecture, February 13

By Joseph Kennedy

Shree Nayar

Shree K. Nayar, a leading figure in the science of imaging, will deliver a University Lecture on "The Computational Camera: Redefining the Image." The lecture will take place on Thursday, February 13, at 8:00 p.m., in the Low Library Rotunda.

Nayar's lecture will focus on his recent work on the creation of novel cameras. The traditional notion of a camera is based on the concept of a pinhole (camera obscura). It produces an image by selecting rays of light from the scene in a specific manner. Only those rays that pass through the iris of the camera's lens are captured. Although this selection appears natural, it turns out to be highly restrictive.

In his lecture, Nayar will introduce the computational camera, a device that embodies the convergence of the camera and the computer. Using unconventional optics, it selects light rays from a scene in radically different ways and a suitable algorithm to manipulate the selected rays to produce new forms of visual information. Nayar will present examples demonstrating how the computational camera redefines the very notion of an image, and hence has the potential to impact the very nature of communication.

Nayar is the T.C. Chang Professor of Computer Science at the Fu Foundation School of Engineering and Applied Sciences. He heads the Columbia Automated Vision Environment (CAVE), a laboratory dedicated to the development of advanced computer vision systems. Nayar's research focuses on three areas: the creation of cameras that produce new forms of visual information; the modeling of the interaction of light with materials, and the design of algorithms that recognize objects from images. His work is motivated by applications in the fields of computer graphics and robotics.

Nayar has received the prestigious David Marr Prize twice, in 1990 and 1995, the David and Lucille Packard Fellowship (1992), the National Young Investigator Award (1993), the NTT Distinguished Scientific Achievement Award (1994) and the Keck Foundation Award for Excellence in Teaching. He has published more than 100 scientific papers and has over 30 awarded and pending patents on inventions related to imaging, vision and robotics.
