Light-in-Flight Paper accepted to Siggraph 2013!

A recent project focused on reducing the cost of Transient Imaging.  Transient images are effectively videos that depict light-transport at the timescales of light-transport; they allow you to see light 'in-flight' as it bounces around the scene. 

This has been done in the past with extremely expensive optical setups costing hundreds of thousands of dollars that involve very short laser pulses and so-called streak-cameras.  However, it is possible to accomplish much the same effect with modifications to off-the-shelf hardware for on the order of only a $1000.  The paper describing this has been accepted to SIGGRAPH 2013 and there will be an accompanying technical demo in the Emerging Technologies area.

You can get an idea what the project does from the following video. If you happen to be attending SIGGRAPH this year, please stop by the booth to find out more!

Stochastic Deconvolution Paper Accepted to CVPR2013

My most recent submission on image deblurring has been accepted as a poster at CVPR2013, to be held in Portland Oregon.  The approach is an adaptation of the stochastic random walk used in my earlier Stochastic Tomography paper to image deblurring and handles saturated pixels and boundary conditions naturally.  The submission video gives an overview of the method:

More info is available at the Stochastic Deconvolution website.  The site also includes sample C++ code illustrating the basic method.
