Software
Here are some MATLAB software packages that are relevant to my publications. Except for some third-party libraries sometimes included in the packages, all of the code is © Jean-Francois Lalonde 2006-2011. It can only be used by academic or non-profit, or government-sponsored researchers. It may also be used for evaluation purposes elsewhere. This software comes with no warranty or guarantee of any kind. By using this software, the user accepts full liability.
Please cite the relevant publications if you use this code in your research.
[ Color realism ]
This MATLAB code implements our image realism assessment and recoloring algorithms, as described in our ICCV 2007 paper. Please see the README.txt for more information.
Live code now available on github!
[ Shadow detection ]
Does not require the MATLAB Statistics Toolbox anymore! This MATLAB code implements our learning-based shadow boundary detector, as described in our ECCV 2010 paper. Please see the README.txt for more information.
- Download the code and associated test data here: shadowDetection.zip (2 MB);
- Requires the following 3rd-party software packages:
- Lightspeed Matlab toolbox (at least version 2.4);
- Graph cut Matlab wrapper by Shai Bagon, which uses C++ code by Olga Veksler;
- Relevant publications:
[ Webcam calibration ]
This MATLAB code implements the camera parameters estimation algorithm from the sky observed over time from a static camera. Please see the README.txt for more information.
- Download the code and associated test data here: skyCalib.zip (10.8 MB);
- Requires my sky model implementation;
- This code has been used to calibrate the webcams in the Webcam Clip Art dataset;

[ Estimating illumination from a single image ]
This MATLAB code automatically estimates a probability distribution over the relative position of the sun with respect to the camera. It is divided into several sub-packages, which will become available over the next few months. Most of them require the "parseArgs" package by Malcolm Wood, available on the Matlab Central website.
- Estimate the probability of the sun given the sky:
- Please see the README.txt for more information;
- Requires my sky model code and the lightspeed package by Tom Minka;
- Download the code here: sunProbSky.zip (4 KB).
- Display the sun probability map:
- Please see the README.txt for more information;
- Requires my environment map conversion routines;
- Download the code here: displaySunProb.zip (1.4 MB).
