Interesting technology but not really going to help with green screen extraction. I can see it being useful for scanning an object into 3d with dynamics using multiple cameras. Add in some shader extraction technology (when / if that exists) and some light detection algorithms (which do) and you have an asset. That can be added to a scene realistically.
