Not sure you can do it in QC, but here's some info on color tracking
in CI...

I need to track blobs of color in a live video feed, as close to
real-time as possible. The goal is to find continuous roundish
regions (blobs) of a particular color, and emit their coordinates
and sizes in some way that another process can read.
I've never used Quartz Composer before, and I'm not sure if it can
even do this sort of thing. What I want isn't an image filter --
the output should be just a handful of numbers, not an image. I
found this thread, which suggests that blob tracking may be
possible, but apparently only under Rosetta: http://nuigroup.com/forums/viewthread/2524/
But that thread's pretty old by now too. Can anyone clue me in on
the current situation? Is this the sort of thing Composer can do,
or should I be looking at writing a custom app in ObjC?
Thanks,
