For those of you with digital collections, watch for Polar Rose in February. From their website:
Polar Rose makes photos searchable by analyzing their content and recognizing the people in them.
It’s a great idea. The Polar Rose software identifies pictures of people and places a rose on their lapel (or where their lapel should be). At that point, a tooltip appears, letting you know who it might be. The name is based on other photos of this person already named by others. You can agree with the name or provide/choose another. As you identify people in the pictures, these are added to the database kept by Polar Rose. So, the more people you identify, the better the database will be for everyone.
We provide the data and Polar Rose provides the face recognition algorithms. This has definite possibilities for digital libraries!
