Declan,
Here is a story from the Denver Post Politech readers might find of interest in the "face Recognition" debate:
http://www.denverpost.com/Stories/0,1002,11%257E57823,00.html
Colorado will be taking pictures of people when they get drivers licenses and use face recognition to compare them with mug shots.
It states they are buying the technology and equipment from Polaroid.
I am recommending to my listeners to simply do not do any business or tourisim with the state of Colorado, The City of Tampa, Florida, Polaroid or anyone else who thinks they wish to implement this system or make a profit from it.
Cheers,
Mick Williams

The archives, or a search engine, will turn up many past discussions we've had of face recognition and biometrics.
One of the interesting things is that _ear shape_ is one of the best correlation features.
Of course, to measure ear shape the camera has to have a good view, unobscured and at close enough range to get a decent number of pixels. (This makes sense, that ear shape would be a good metric. I've been noticing the variations in ear shapes since I heard about this scheme. Also, I can imagine the various conformal transformations--different angles of view, for example--preserve certain relationships well.)
I can believe some kind of automated face recognition is being done with points of entry, such as international airport arrival points, but I find it hard to swallow that "crowd shots" from overhead cameras can do anything meaningful.
The Tampa action may be mostly social engineering: "We're watching you!"
