Facebook Uses Face Recognition To Help Tag Photos

It's no secret that Facebook's Photo product is the most popular photo sharing service on the web�by a huge margin. And one of the key features that made it so popular has been tagging, which lets you associate your friends with the photos they're in ? Facebook says that 100 million photo tags are added�every day. Which is all the more amazing given that tagging is kind of a pain. Fortunately it's getting better. Back in October Facebook launched a feature that had some face detection built in ?�if someone appeared in multiple photos in the same album, Facebook would group them together and ask you who that person was, allowing you to tag them in one fell swoop. Now it's improving on that by using face recognition technology to guess who the person is, using your network of friends as a reference.
