Yes, we have! In fact, there's a
really good example on FIRST Forge to find reflective tape (or other?). It's one of the coolest thing's I've worked with to date, for sure. I couldn't be more excited about it.

Those particles give you the essentially the loops.
NOTE! the threshold is set to the color of the color hoop, so the binaryimage will only be on if it fits those requirements.
Good luck!

Sidenote: You can get these "bla bla bla" arguments from the NI Vision Assistant. Simply run an HSL threshold over your image (after acquiring one, of course) and mess with the cool sliders until it's only seeing the tape.
