... of the CGI industry.
Many have tried and many have failed.
I've known a couple of people who have been involved in development of systems to do this, and I've seen a lot of companies come and go who have promised such systems at industry shows (quite a few have claimed to be defence funded which is a little scary).
None that I know of have borrowed too heavily from public algorithms to do this (although one did claim their system generated some splendid comical morphing effects when mis-applied!).
There are quite a few commercial systems out there (have a look at highend3d.com's lists etc), but I guess this isn't what you're after.
As I understand the state of the art, simply following a feature on an image frame (using fairly simple algorithms) is not a difficult problem in itself. The tricksy part comes when you need to follow a feature (e.g edge / point) which is changing itself during the sequence, or even in the worst case being eclipsed by another feature (person walking in front of camera).
Know it doesn't help, and I hate to be negative, but I don't think you're gonna see a sourceforge motion-tracking project any time soon.
