Pattern tracking

Has anyone had successfully managed to do pattern tracking in Processing.
In Eyesweb it's called Posture Recognition. Jitter for Max/MSP has cv.jit that does it for you. In Processing it would have to be hand coded, but should be possible.
In v3ga's excellent blob bounding box example

Imagine not tracking blobs, but any blobs that looked like the letter v (in his vid).
Currently I am using Eyesweb posture recognition to track objects on the camera (such as circles/squares) and then sending that information via OSC to Processing, which is very processor intensive.
Was wondering if anyone had any thoughts on this?

Yeah thanks Ethan, it doesn't really do pattern tracking though, well it could if you take the globEdgePoints() and normalize them into a simpler shape to see if they match. I found the Xtra a bit too slow in Director. Not tried it in Processing though.
