Computer scientists have developed a new face recognition algorithm called GaussianFace which outperforms humans for the first time in challenging real-world conditions. The algorithm normalize each face into 150 x 120 pixels by transforming it based on five features: the position of both eyes, the nose and the two corners of the mouth. The accuracy is 98.52% compared to human accuracy at 97.53%. There's a database at umass.edu that captures much of the face variation by labeling faces in the wild which have 13 000 faces of almost 6000 public figures collected from web.

"which have 13 000 faces of almost 6000 public figures collected from web"
1) The average person has 2.1 faces? WTF Harry Potter's first novel? (Sorry if I just spoiled it for the one dude on the planet who hasn't read the book / seen the movie year, oh and also Darth Vader is Luke's father, BTW)
2) "collected from web" So the story sounds like we can tell identical twins apart, but the reality is they can tell the difference between goatse and tubgirl and the feels meme guy. Well, OK.

From TFA:
So the algorithm can tell you that a screen cap of Luke Skywalker calmly listening to Obi Wan in ANH is the same person in a screen cap of Luke shouting "that's not true, that's impossible!" with a scrunched up face at the end of TESB.
Not entirely clear from the article and the abstract, is if they gave the algorithm pair of images to pass/fail, or a cache of 13,000 images and told it to find all the matches.
In regards to your second point, there actually are two faces for the "feels guy", a wrinkly human and an anthropomorphic frog.
The fleas have smaller fleas, upon their backs to bite them, and those fleas have lesser fleas, and so ad infinitum

with a scrunched up face
Not to mention scarring from the car accident...

Hmmm, Star Wars and Goatse reference in one post about facial recognition.

Damn, you spoiled it to me. Up to now I didn't even know that Luke was in Hogwarts! ;-)

Or out of 2.1 persons there's one public person.

good point, perhaps even a bit understated.

Can anyone doubt that for any skill a computer will out perform it with enough engineering? Increasingly, pattern recognition is old hat...not something at which we handily beat computers.
The thing we have left over the machine is flexibility: A bunch of effective organic algorithms that can be selectively and effectively applied to a vast array of situations. Once, not if, computers can integrate a multitude of algorithms under context-sensitive goal-selective control, we will be beat, or we will integrate them into ourselves.

Catch is that figuring out how to make a machine to do it is a challenge in itself even if you know it can be done.

Until we figure out how we can make a machine figure it out, that is.
