Photo recognition software tells you where you are

"You are lost in a foreign city, you don't speak the language and you are late for your meeting. What do you do? Take out your cellphone, photograph the nearest building and press send. For a small fee, photo recognition software on a remote server works out precisely where you are, and sends back directions that will get you to your destination. That, at least, is what two researchers at the University of Cambridge in the UK hope their software will one day be used for," reports New Scientist.
