It is likely a real machine vision system if it was the same system our former company evaluated.

It worked by camera tracking the shelves contents, and would adjust the inventory level for a specific customers actions. And finally, tracked the incremental mass change during the checkout process to cross reference label swap scams etc.

Thus, people get flagged if their appearance changes while in the store, mass of goods is inconsistent with scanned labels, or the cameras don't see the inventory re-stocked.

You would be surprised how much irrational effort some board members put into the self-checkout systems. Personally, I found the whole project incredibly boring.... so found a more entertaining project elsewhere... =3
