Reasoning About Light

PLACE:	Clark 110
EVENT:	CIS Seminar
DATE:	April 15, 2008
TIME:	1:00 - 2:00 PM

Abstract:

Much While research on 3D photography has enjoyed tremendous success in recent years, many everyday objects are still difficult or impossible to scan in 3D. One fundamental stumbling block is that typical algorithms do not consider the effects of light transport---the sequence of bounces, refractions and scattering events that may occur when light interacts with an object. These events are ubiquitous, and dominate the appearance of objects with transparent materials or shiny surfaces. > In this talk, I will present a series of 3D photography algorithms that explicitly reason about how light flows through (or around) real objects. These algorithms rely exclusively on 2D photos and seek to infer the specific optical events that occur from light leaving a source to reaching a specific pixel. I will show that despite the apparent intractability of this endeavor, it has proved quite successful in capturing detailed "3D photos" of many common objects with complex optical properties

Brief Biography:

Kyros Kutulakos is an Associate Professor at the University of Toronto where he has been on the faculty since 2001. His research interests are mainly in the area of computer vision, with an emphasis on geometric reconstruction problems. He is the recipient of a Sloan Fellowship, an NSF CAREER award, a PREA award from the government of Ontario, and four best paper prizes (David Marr Prize in 1999, David Marr Prize Honorable Mention in 2005, Honorable Mention at ECCV 2006, and Best Student Paper Award at CVPR 1994). He also served as the Program Co-Chair of the 2003 Computer Vision and Pattern Recognition Conference.
