Facial Recognition Lets Apps Guess Your Age
A service offered by Face.com is almost as good as humans at judging someone's age from a photo.
Age estimated: In reality, Alec Baldwin is 53, so the
estimated age range is correct. Photos of actors and models are often
judged by Face.com's system be younger than they really are.

Web users have become used to the idea that most of what they read
online—whether it's Facebook comments or personal e-mails—is scanned by
software that tries to serve up relevant ads. But soon online
advertising companies may start serving up ads based on the age of
people in photos that you're viewing on a page.
That's thanks to startup
Face.com,
which already offers a face-recognition service that websites or apps
can use to count the number of faces in a photo, tell their gender, or
match them to known individuals. Starting this week, that service will
also guess the age of the faces it spots in photos and ad networks and
other Web and mobile companies already have plans to use it.
"You send us a photo with a face in it, and it'll send back an
estimate of their age," says Gil Hersch, CEO and cofounder of Face.com,
which is based in Tel Aviv, Israel. To use the service, programmers have
their software send photos to Face.com over the Internet and receive
back the results of the analysis. Face.com returns an upper and lower
range on the age of the face, a specific estimate, and a confidence
score.
A demonstration site shows the information that Face.com calculates from a photo.
"We heard from a bunch of clients that they're interested in adding
age detection for a variety of applications," says Hersch. "Ad services
is one." He says some ad services companies are already using the
gender-detection capabilities of Face.com's technology to help choose
which ads to display next to a photo.
The operators of video chat sites that pair up strangers have also
expressed an interest in age detection, says Hersch. They already use
Face.com's service as a kind of safety feature to ensure that people are
showing video of their faces. "They're trying to match you with other
chatters, and age detection could help with that," says Hersch.
Roughly 45,000 software developers are currently registered to use
Face.com's service, which Hersch says processes "a few billion" photos
every month.
Face.com's ability to guess age comes from training software on a
collection of hundreds of thousands of photos that had been labeled by
people who made their own attempts to judge the age of people in them.
Face.com's software matches human guesses of the age of a face in a
photo about 90 percent of the time, but the company has not compared its
accuracy against the true age of people.
