About

I received my PhD from the Computer Graphics Group, part of the Computer Science and Artificial Inteligence Laboratory (CSAIL) at MIT in June 2011. My advisor was Prof. Frédo Durand. My thesis was on efficient data structures for video processing. I also did research in rendering and graphics hardware.

I did a postdoc with the Interactive 3D Technologies Group at Microsoft Research, Cambridge (UK).

I am currently a software engineer at Google[x].

Code

I have released the source code to the GPU version of the Bilateral Grid. It can be found on the project page.

Bilateral Filter
A standalone MATLAB implementation of Paris and Durand's A Fast Approximation of the Bilateral Filter using a Signal Processing Approach (ECCV 2006).

Version 1.11 (11/5/2007)

Version 1.0 (03/07/2007)

Local Histogram Equalization
A standalone MATLAB implementation of Local Histogram Equalization using the Bilateral Grid.

Version 1.1 (10/19/2007)

2D Hilbert Curve Generator
A standalone C# implementation of 2D Hilbert Curves. Unlike most samples found on the web, this program actually returns an array of points over which you can iterate to walk the unit square.

Version 1.0 (05/15/2009)

Some Hilbert curves of orders 1 through 10 directly usable as C/C++ arrays: 1 2 3 4 5 6 7 8 9 10

I am emacs/vim ambidextrous: .emacs .vimrc

I use GNU Screen: .screenrc

I map CAPSLOCK to CTRL and the useless right "Windows" key to CAPSLOCK: Swap CAPSLOCK and Right Windows Key

All the code is released under the MIT License.
