I am an n-th year graduate student in computer graphics. My advisor is Prof. Frédo Durand. I'm interested in pretty much all areas of graphics.

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)

• Warning: interface has changed (slightly)!
• Now supports user-specified inputMin and inputMax for inputs that don't range between 0 and 1. By default, they're set to the min and max of the input, which is probably not what you want.
• Supports passing [] as the edge input for normal bilateral filtering. E.g. output = bilateralFilter( input, [], 0, 100, ss, sr ); % input is the L channel of an image, which should have a range of [0,100].
• Minor update from 1.1: adds additional error checking on the inputs.

Version 1.0 (03/07/2007)

• Download (rename to bilateralFilter.m)
• Supports images that are not between 0 and 1.
• sigmaSpatial now defaults to min( width, height ) / 16
• sigmaRange now defaults to ( max( edge ) - min( edge ) ) / 10.
• Removed all the debugging outputs in the return value.

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

Version 1.1 (10/19/2007)

• Initial release.
• Includes readPFM.m and writePFM.m for reading and writing Portable Float Map (PFM) images.

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)

• Initial release.
• Computes curves on the unit square only and returns results as floating point numbers. The next release will support integers (both as 2-vectors and as 1D indices) and doubles.

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
