An awkward resemblance to a certain eigenface might get you pulled aside in Las Vegas. Prof. Hilbert is probably spinning in his grave.

If the eigenfaces shown in the wikipedia article are anything to go by, then anyone who actually looks just like *one* of these faces needs to be pulled over and analysed so that we may learn more of their distant planet.

Heh, eigenface...

It thinks Tom Baker is Anthony Hopkins (65%)... I dunno...

Audrey Tautou is in their database, so I tried a few of her...
  1. Audrey Tautou - correct 73%,
  2. Audrey Tautou - Ayn Rand 71%
  3. Audrey Tautou - Isabella Rossellini 73%
  4. Audrey Tautou - correct 72%
  5. Audrey Tautou - correct 73%
Of course the correct matches were against three different images in their database and for that last one Courtney Cox and Alyson Hannigan both scored 72% (there were three more >=70%).

I wonder what factors are considered the biggest technical limitations. Processing power? Photography, like lighting conditions? Obviously the angle the picture is taken at is a huge problem...

Think of all those poor hard-partying folks who won't be able to use the ATM on Sunday morning. It will ruin the brunch industry.

People have told me Keifer Sutherland and Matt Damon, but I guess I look like Frank Oz, John Cage, and Ingmar Bergman. And some other old people.

Strange, I'd say the second picture (aka Ms. Ayn Rand) reflects my image of Audrey Tautou the most.

Also, I'm not entirely sure what the Australian department of defense is doing with a poster image from Dirty Pretty Things on its website (check the URL of the third image).

Well apparently, I look like Bruce Springsteen. Can't quite see it, myself.

Hmm, I look like Jackie Kennedy. Sweet.

It says I look like....

Pierre De Coubertin?!

It's the spatters of blood and brain tissue.

Eigenfaces are quite sensitive to the alignment of the image, as well as changes in viewpoint and lighting. The example eigenfaces in the wikipedia article seem all to be related to shading, and would probably be of little use in face recognition. The "demo" in the first link is quite useless for anything serious.

FaceIT does not use eigenfaces and is mostly landmark-based.
(I am quite heavily biased towards landmark-based face recognition methods because of my thesis work)

...first pass I match with Jonas Salk; with another picture I match with Guy Pearce. I could do this all day but I'd probably lose my job.

Aung San Suu Kyi (67%)
John Cusack (61%)
...and, God help us all, Alec Baldwin (56%.)

I even matched better-than-50% with Barack Obama.

For reference, this is me.

Oh yeah. Barack Obama.

Buster Keaton 60%?

The site is "undergoing maintenenance" right now, but I did this a while ago (probably on the same site), and it thinks I look like Cate Blanchett. It was surprisingly flattering, actually, even though they matched me with a not so good picture of Cate Blanchett.

A bit boring. Movie reviews from the soldiers' newspaper.

Now their site has records on all of you (well, those who greedy bastards who wedged their way in all at once and brought the site down).

Eigenfaces are one of nearly a dozen methods that show promise in reasonably accurate recognition of individuals, and are one of about 3-4 methods employed in Vegas for our casinos' famous 'blacklist'. I've seen some of these systems in play, and combining the technologies produces eerily strong positive recognition. Still, DHS hasn't picked it up yet, nor did any of its predecessors.

That said, almost all of the facial recognition systems have two flaws: an inability to properly compensate for even some minor differences in facial hair on the same subject, and the 'normalization' of the faces prior to analysis that distorts sometimes prominent features. Some people escape the system by growing a 1-week goatee. Others get wrongly caught because they have a face that when 'normalized' makes them look more similar to people that are of entirely different races.

Umm, for clarity (as I look back on it) the second paragraph of my prior comment is the main stated reason why casinos employ several methods simultaneously. It reduces the error. Also, the last method used is usually a guy on the casino floor sent to compare the individual to a high-res photo for a final determination.

BTW, [this is good]. Thanks, Alex.

Wow, it is very sensitive to alignment - I put in a shot of my right side at about 30 degrees from face-on, and I matched about 70% with, um, Rudolph Valentino, Annette Benning, Audrey Tatou, J-Lo and basically everyone who was in a similar pose.

That, or I actually have an eigenface.

Fun post, ta Rothko...

Monica Seles, Kim Basinger, Muhammad Ali, and Meat Loaf from the same photo?

Johnny Depp or Bruce Willis....wha? I have a few features similar to both those guys, but they look nothing like each other. And who the hell is Heinrich Boll? He's got squirrel cheeks and I don't. Maybe it's the beard. I dunno.
