Webcam feed as Alpha Mask

edited December 2014 in How To...

The title pretty much sums it up. I'm trying to use a webcam feed as an alpha mask on three underlying IP camera feeds. I've been Googling for days now, but nobody seems to have posted any information on how to use a live video as a mask. Being pretty new to processing, I honestly don't even know where to begin. I've looked into blend modes, tint, pixel array (will supposedly be too slow for live video), but none of these seem to be what I'm looking for. Any help is greatly appreciated, as it's going to be exhibited on monday and I'm getting nervous. Seemed like such a trivial part of the code but turns out to be the biggest headache :/
