In this talk, we will first present the concept of a computational
camera. It is a device that embodies the convergence of the camera and
the computer. It uses new optics to select rays from the scene in
unusual ways, and an appropriate algorithm to process the selected
rays. This ability to manipulate images before they are recorded and
process the recorded images before they are presented is a powerful
one. It enables us to experience our visual world in rich and
compelling ways. We will show computational cameras that can capture
wide angle, high dynamic range, multispectral, and depth
images. Finally, we will explore the use of a programmable light
source as a more sophisticated camera flash. We will show how the use
of such a flash enables a camera to produce images that reveal the
complex interactions of light within objects as well as between them.
Biography:
Shree K. Nayar received his PhD degree in Electrical and Computer
Engineering from the Robotics Institute at Carnegie Mellon University
in 1990. He is currently the T. C. Chang Professor of Computer
Science at Columbia University. He co-directs the Columbia Vision and
Graphics Center. He also heads the Columbia Computer Vision Laboratory
(CAVE), which is dedicated to the development of advanced computer
vision systems. His research is focused on three areas; the creation
of novel cameras, the design of physics based models for vision, and
the development of algorithms for scene understanding. His work is
motivated by applications in the fields of digital imaging, computer
graphics, and robotics.
He has received best paper awards at ICCV 1990, ICPR 1994, CVPR 1994,
ICCV 1995, CVPR 2000 and CVPR 2004. He is the recipient of the David
Marr Prize (1990 and 1995), the David and Lucile Packard Fellowship
(1992), the National Young Investigator Award (1993), the NTT
Distinguished Scientific Achievement Award (1994), the Keck Foundation
Award for Excellence in Teaching (1995) and the Columbia Great Teacher
Award (2006). In February 2008, he was elected to the National Academy
of Engineering.
