Source Code for "Scale Invariant Cosegmentation for Image Groups" can be downloaded here. This code base uses OpenCV-2.1 to compute the data/smooth term. If you are using OpenCV-2.2 or later version, you might want to replace the GMM component with this one.

Once upon a time, we (with my awesome college classmates) built a general particle system for wonderland, and used it to simulate several natural phenomena like rain, snow, and fire.etc in a collaborative 3D virtual world. Report and code could be downloaded here.
