The recent experience of an acquaintance offers a use for camera phones: Her duplex was invaded by a snake, forcing one offspring to yell for it to be killed, another to demand its safe return to the wild, the mother to scream from a safe distance, and the father to frantically Google the snake’s appearance to find out if it was poisonous.
How hard would it be to have a sort of “skin recognition” where the scared human takes a picture of the snake’s skin, uploads it to a website and receives details of the snake, its threat level and the best way to return to somewhere less intrusive. (My friend lobbed two encyclopedias at it and, while it was devouring that, caught it in a fishing net.)
Does anything like this exist? Could it? How hard would it be?
