How will you avoid gating the color of the object you're trying to track as well?
To use your method below I'd suggest using some combination of [separator] and [pix_background] to create a mask so that [pix_blob] (or the color gate, depending on the setup) only affects new objects introduced into the environment. That's very incomplete suggestion, but I don't have pd in front of me right now to toy with examples. Best of luck, let me know if you get a patch together, I'd like to see it. -Ben >Wondering the best solution for color tracking in Pd-extended.
