My question is in regards to this patent. They are claiming that their method of exclusive or'ing a set of vectors to estimate camera network topology. Is it fundamentally valid to patent such a method for anything?

As I can see, all this patent claims is that: If one cameras field of view (window), is occupied, and simulatenously another cameras field of view isn't, then they are not connected.

I think this is just logic which can be applied to anything. What do you guys think?
