Figure out the bug

It seems all the calculations do nothing - the matte just stays the same as the initial input. Weird.

Everything "seems" to work - the output is definitely wrong. I think I'll have to recheck the math that goes on for each frame.

I get alphamaps that "resemble" the ground truth i some vague way. Definitely need more research on the gaussian model generated for each pixel.
