Re: How many billions of dollars are being spent chasing this?
millions of pictures of dogs at all different angles before it can recognise a dog with reasonable accuracy. A baby only has to be shown a dog once or twice and it knows "dog"
Unfortunately I only seem to get quizzed about buses, store fronts, traffic lights, "crosswalks" and fire hydrants whenever I have to prove I'm not a robot. I assume they'll get around to "people", "dogs" and "babies" at some stage - until then, stay off the streets!
