I've updated the Deface face recognition library that I created last year to take advantage of the new Vector class and some other improvements.

It should be fast enough for some limited real-time use now. For instance, the demo below typically finds my face in < 80ms once it's aquired it. That's only about 12fps, but for certain applications that would be sufficient. And I'm sure that the tracking can be improved a lot. There's no real prediction now as is, nor position averaging, etc.

Allow this to use your webcam if you have one. If you don't, you're out of luck.
