Face recognition software is, it’s well known, crap.
Cat recognition software is a different story.
Flo is a cat. Flo likes to bring home dead animals sometimes. Flo’s owner doesn’t like this. Flo’s owner rigs up an electronic cat-flap attached to image recognition software.
It works. Flo only gets it when unencumbered by small dead animals. It also helps to keep out unwanted visitors like skunks and birds.
It’s like 1984 for cats.
