Polar Rose is a new search engine now being tested that will allow you to find anyone in any photo on any site. Type in the name of a person you know, and find pictures of that person all over the web, on sites like MySpace or blog pages using face-recognition technology.
The Polar Rose search engine works by providing users with a special web browser plug-in that anyone can use with a web page that contains a picture. The process begins with the Polar Rose software identifying the parts of the picture that are actually images of people. For example, in a backyard barbeque snapshot, you might find a variety of elements in the picture, like grills, decks, chairs, and different people standing around. The software picks out the faces and puts a small "rose" icon next to each one (see example picture here).
