The real discrimination is continued legacy and athletic admissions which artificially inflate the number of white students (discriminating against Asians and other minorities).
This is a question we’ve gotten quite a bit (second author here).
A good intuition is that if it were easy to do it already with any background, professional studios wouldn’t be spending so much money on green screens. Background subtraction is pretty poor in general without very constrained setups. Our goal is really to provide professional quality without any of the equipment.
And can your solution do what studios want, namely process a 4K-video artifact free, when played back on a cinema screen? I doesn't look like that tbh if I watch the second video ("Ours real" is your work?).
And yeah, it requires constrained setup and a lot of additional work, because even before you "subtract" the background you have to think about lighting (your demo video might have very nice background matting, but the lighting is off, so it's relatively useless except for toy applications (which there are a lot).
Also: did you compare somewhere withe the very basic fixed-exposure method? Beause for fixed exposure, background and camera placement I suppose this should work just as well... Still I think this is a really cool project, I didn't get disappointed like with the last link of that sort, where someone tried the same with horrible artifacting.
