Wondering the best solution for color tracking in Pd-extended. I'd like my solution to be cross-platform so that rules out PDP and friends.
All I've come up with is to use [pix_blob] to track the color, and to try to minimize the tracking color in the background. There's probably a Gem object where I can "gate" a color i.e. eliminate a color from a pixel if it is less than a certain amount. In my rendering chain after my webcam I'd gate the color I am trying to track, then use [pix_blob] with a color weight of entirely the tracking color.
Is there a better way?
