I am working with the Light Field Camera Array group on synthetic aperture imaging and reconstructing 3D shape using arrays of cameras and projectors. Here is an example illustrating synthetic aperture imaging:
|Cameras aimed at bushes||View from one camera of students behind bushes||Synthetic aperture image|
|Synthetic Aperture Imaging. In this experiment, an array of 45 cameras was aimed at students hidden behind bushes (left image). It is almost impossible to make out the students from a single camera image (center). We can combine images from all 45 cameras to automatically construct a synthetic aperture image (right) in which the students behind the bushes are clearly visible. For more examples and details, please see [VV04], [VV05].|
The ability to "see through" dense occlusions makes synthetic aperture imaging a potentially powerful tool for surveillance. Using simple projective geometry analysis, we have developed a simple and robust calibration procedure for synthetic aperture imaging, and a real-time system for tracking a person as he moves through a crowd. Synthetic aperture imaging allows us to simulaneously exploit both shape-from-stereo and shape-from-focus methods for 3D reconstruction. We have explored the space of 3D reconstruction methods enabled by a synthetic aperture in collaboration with Rick Szeliski's group at Microsoft Research [VV06].
We have created an archive of light fields acquired using our camera array and light field gantry for researchers to download and use in their work.

I joined the PhD programme in computer science at Cornell in fall 2000, where I picked up ice hockey. After a year, I transferred to Stanford and graduated in April 2007.
