Talk Title: Transport-Aware Cameras

Talk Abstract: Conventional cameras record all light falling onto their sensor regardless of
its source or its 3D path to the camera. In this talk I will present an
emerging family of coded-exposure video cameras that can be programmed to
record just a fraction of the light coming from an artificial source---be it a
common street lamp or a programmable projector---based on the light path's
geometry or timing. Live video from these cameras offers a very unconventional
view of our everyday world in which refraction and scattering can be
selectively blocked or enhanced, visual structures too subtle to notice with
the naked eye can become apparent, and the flicker of electric lights can be
turned into a powerful cue for analyzing the electrical grid from room to city
scale.

I will discuss the unique optical properties and power efficiency of these
"transport aware cameras" through three case studies: the ACam for analyzing
the electrical grid, EpiScan3D for robust structured-light 3D imaging, and
EpiToF for robust time-of-flight imaging. I will also discuss our initial
progress toward designing a computational CMOS sensor for
coded two-bucket imaging---a novel capability that promises much more flexible and
powerful transport-aware cameras compared to existing off-the-shelf solutions.

Speaker's Biography: Kyros Kutulakos is a Professor of Computer Science at the University of
Toronto. He received his PhD degree from the University of Wisconsin-Madison
in 1994 and his BS degree from the University of Crete in 1988, both in
Computer Science. In addition to the University of Toronto, he has held
appointments at the University of Rochester (1995-2001) and Microsoft Research
Asia (2004-05 and 2011-12). He is the recipient of an Alfred P. Sloan
Fellowship, an Ontario Premier's Research Excellence Award, a Marr Prize in
1999, a Marr Prize Honorable Mention in 2005, and four other paper awards
(CVPR 1994, ECCV 2006, CVPR 2014, CVPR 2017). He also served as Program
Co-Chair of CVPR 2003, ICCP 2010 and ICCV 2013.
