Here is a marketing tip John, if you are the inventor of a new breakthrough technology give it a name
I have no interest in marketing something which has no commercial value.
All it's really doing is a direct comparison between two different solid objects and when you have two identical objects then the depth mapping for each individual point on each object is precisely the same regardless of the angle to camera therefore when each point is connected in off centered photos we get perfect rotation but when something is even slightly out of alignment then we can immediately see it. It's like the floating part of an altered image that you get when stereoscopic images are viewed stereoscopically.
Now when applied to this problem we are at an advantage because pretty much by definition we all have our own unique face with each landmark having its own unique position in space and like the celebrity/lookalike examples above there is always a problem using this technique with non identical people.
