Nema na čemu (aka "de nada", literally "has not on what"). The above plan is open source, anyone can use it, just attribute the idea to me and the algorithm to you and we'll be famous.

A side note: the title of the thread gets me thinking every time I see it: we should also have point, line and volume cameras, with options to extend into more dimensions as technology permits.
