I'm working on a little project involving the faces of twitter users via their profile pictures.
A problem I've encountered is that after I filter out all but the images that are clear portrait photos, a small but significant percentage of twitter users use a picture of Justin Bieber as their profile picture.
In order to filter them out, how can I tell programmatically whether a picture is that of Justin Bieber?

A better idea might be to trash all images that appear in the feed of more than one user - no recognition needed.
