Ramesh Raskar,
Looking Around Corners: New Opportunities in Femto-Photography
Abstract:
Can we look around corners beyond the line of sight? Our goal is to exploit the finite speed of light to improve image capture and scene understanding. New theoretical analysis coupled with emerging ultra-high-speed imaging techniques can lead to a new source of computational visual perception. We are developing the theoretical foundation for sensing and reasoning using Femto-photography and transient light transport, and experimenting with scenarios in which transient reasoning exposes scene properties that are beyond the reach of traditional computer vision. (Joint work with a large team, see raskar.info/femto)
Bio:
Ramesh Raskar joined the Media Lab from Mitsubishi Electric Research Laboratories in 2008 as head of the Lab?s Camera Culture research group. His research interests span the fields of computational photography, inverse problems in imaging and human-computer interaction. Recent inventions include transient imaging to look around corners (Femto-photography), next generation CAT-Scan machine, imperceptible markers for motion capture (Prakash), long distance barcodes (Bokode), touch+hover 3D interaction displays (BiDi screen), low-cost eye care devices (Netra) and new theoretical models to augment light fields (ALF) to represent wave phenomena.
He is a recipient of TR100 award from Technology Review, 2004, Global Indus Technovator Award, top 20 Indian technology innovators worldwide, 2003, Alfred P. Sloan Research Fellowship award, 2009 and Darpa Young Faculty award, 2010. He holds over 40 US patents and has received four Mitsubishi Electric Invention Awards. He is currently co-authoring a book on Computational Photography. raskar.info

[@Shammikaze]

Awesome. Not sure what else to say. Mind blown.

[@CurrentGamer]

Wish I could fast forward and see this project in 5 years!!

[@rockker5]

Awesome!

[@ruhikerem]

This's good news ,

[@Aristosek]

OK, but how that ultra-fast camera working ?

[@alienkishorekumar]

Take as many pictures as possible. In this case take a pic in one femto second i.e. , 10^(-15) according to Wikipedia. But this is not easy, so it's kind of costly.

[@AliAhmadMD]

so rectilinear propagation of light is wrong??

[@jtocwru]

Nope. This is like those 90-degree miniature golf / putt-putt holes. If you bank your shot just right, your ball can come back to its starting point.

[@Mrster]

Blade Runner!

[@horndog646]

I just got mindfucked

[@masterkevkev]

Mind : I can understand this!....
*Sees first equation*
Mind : FFFFFFFUUUUAAAA DIVIDED BY TIME DISTANCE SUBTRACT SPACE WUUUUUUT~!?
XD...

[@CrazyPedroDoido]

4:50 to 5:10
IF YOU GO TO THIS EXTREME... you can see something SKIP!!!
what are you afraid of? saying something wrong...
Seems fake to me, again, just like the video posted on MIT's home page

[@JameBlack]

He meant Cthulhu

[@jtocwru]

He said, "If you go to this extreme, you can see something new."
