Recognizr is an app for the Android platform which allows you to simply snap a picture and automatically pair up the face with publicly-available data and information stored on your phone.
Created by the guys at The Astonishing Tribe (or tat for short) and leveraging Polar Rose’s facial recognition platform, Recognizr not only can connect faces with your mobile device’s address book, but it can match the person’s face to social networking profiles and automatically allow you to identify the user by face.http://www.youtube.com/watch?v=5GqJHaNRlas
The main downside to the app at this point is that it requires that participants all be users of the mobile app in order to be recognized, which seriously diminishes its usefulness. Hopefully, that will change with time, and anyone sharing facial data on social networks could participate. At this point, the app is just in the prototype stages, but The Astonishing Tribe guys expect to offer a version of app in the Android Market in the coming months.
