The whole process relies on some pretty sophisticated work by our brains and bodies, and anyone who’s ever dabbled in computer vision or artificial intelligence in general can tell you that teaching a computer to recognize physical objects is no small feat. Just as it’s easier to determine location by having a human being narrow it down for you, it’s easier to distinguish objects computationally if you can limit the field, and if you can label the ...
