yet another motion tracking question

i am looking for a solution outside max for computer vision.
max has some great cv objects but even the best (cv.jit ?) don’t offer what
i need-
continuous blob tracking and contour ( a.k.a silluate, a.k.a perimeter)
coordinates.
best i found outside max is freeframe plugin
"contour< http://vvvv.org/tiki-index.php?page=UserPagemarc_s>"
(source included) that depend on opencv, but they are vvvv specific as they
don’t follow the freeframe spec. (i got them to load in max after adding
opencv bin to path). is there a solution that can connect (via tcp/udp) to
max, is affordable and isnt a code-in-C solution (opencv)?
eyesweb cant keep blob Id and it dont have contour (afaik).

here is what best case scenario should do be able to do (Han strikes
again..)

Here’s something interesting:

http://irc.bu.edu/faculty/sclaroff/ivc/ActiveBlobs/approach.html

Rather than subtracting the background and tracking everything that moves, this approach seems to key in on the items of interest using shape and color information and ignore everything else. This stuff is pretty old, and the code link is defunct. Do any of today’s cv tools have some kind of similar function? Sort of the opposite of background subtraction…
