Accurate Eye Tracker

ashpash's icon

Okay, so I'm trying to create an eye tracker where I can find a person's entire eye and then darken underneath it - to give the illusion of "bags under your eyes." I have been working with the eye tracker patch - changing the threshold etc but it doesn't seem to focus the way I want.

Any suggestions would be appreciated :)

Below is the patch, I'm currently working with

Max Patch
