Facebook's Face Identification Project Is Accurate 97.25% of the Time 149

kc123 tips news that 'DeepFace,' the software research project created by Facebook engineers to identify people in pictures, is now accurate 97.25% of the time. In other words, it's almost as good at recognizing faces as humans, who are able to determine whether two photos show the same person 97.53% of the time. The article says DeepFace reaches that level of accuracy "regardless of variations in lighting or whether the person in the picture is directly facing the camera." It continues, "DeepFace processes images of faces in two steps. First it corrects the angle of a face so that the person in the picture faces forward, using a 3-D model of an 'average' forward-looking face. Then the deep learning comes in as a simulated neural network works out a numerical description of the reoriented face. If DeepFace comes up with similar enough descriptions from two different images, it decides they must show the same face. ... The deep-learning part of DeepFace consists of nine layers of simple simulated neurons, with more than 120 million connections between them. To train that network, Facebook’s researchers tapped a tiny slice of data from their company’s hoard of user images—four million photos of faces belonging to almost 4,000 people."

    When are they planning to connect face identification with the street/store surveillance cameras? Then they could know who is where anytime of the day unless you wear big hats, large sunglasses, fake beards etc.

    All it takes is to be identified once. Just one friend snapping a picture of you & pals at a wedding,who then posts the picture on FB, and dutifully identifies each person in the photo. After that, every image of you available on the web will be linked to you. That picture of you puking your guts out at some drunken frathouse blowout that you hoped everyone had forgotten about will now be on the first page of a Google search on your name.

    I don't have a facebook account. So how I can disable the option of my face being recognized and tagged by facebook in pictures uploaded by others?

    I never signed up to facebook. A number of my friends however did. They 'invited' me to join facebook by giving it my email address to facebook. It got a little insane with the facebook reminders so I 'unsubscribed'. In doing this, I created a hidden profile which is blacklisted.

    My friends upload images of me to facebook. Facebook cookies on my computer track me when I visit any page which has the facebook button on it. My email provider Yahoo may well be sharing information about me with facebook (without my knowledge). Eventually facebook will gather all the connecting pieces of information on me to have a face, an email, and a browsing (possible purchasing) history.

    Just because you can 'opt out' doesn't mean that they're not doing it anyway in the background. I'm not comfortable knowing that these people know more about me than I remember about myself.

    Facebook won't [at least, publicly] autotag you unless you actually have an account, because otherwise there's no account to associate your face with. They may well do this internally, but that information isn't available to users if so. Of course, someone else can create an account "on your behalf" and then those photos can be associated with that identity, and thus with one another; that's linked to your identity practically but not directly.

    ...because they all look alike? I heard they were all really smart and know martial arts, too.
