ClassX is GPL, and GPL is incompatible with ECL 2.0, so please make sure that if you do do something based on ClassX you do not commit it to the MH repo.

In terms of video tracking aka Interactive Region of Interest, ClassX [1] developed at Stanford delivers with the same kind of technology as the "GaliTracker" but it has been "open sourced" [2], which means the advanced detection algorhitms are available to Matterhorn. Thus I'd suggest to anybody interested in integrating such features with Matterhorn to take a look at ClassX.
