Computers Outperform Humans at Recognizing Faces

seven of five writes "According to the recent Face Recognition Grand Challenge, The match up of face-recognition algorithms showed that machine recognition of human individuals has improved tenfold since 2002 and a hundredfold since 1995. 'Among other advantages, 3-D facial recognition identifies individuals by exploiting distinctive features of a human face's surface--for instance, the curves of the eye sockets, nose, and chin, which are where tissue and bone are most apparent and which don't change over time. Furthermore, Phillips says, "changes in illumination have adversely affected face-recognition performance from still images. But the shape of a face isn't affected by changes in illumination." Hence, 3-D face recognition might even be used in near-dark conditions.'"

Great, now commercialize it..

[QuantumG]

It's really annoying how much of this research never gets turned into product.. or, worse yet, it gets embedded in some proprietary piece of shit hardware instead of being released as a reusable component. I'd love to add some good facial recognition to my pet robot, but I'm not buying your watt sucking camera.

Yeah facial recognition software has been a US Customs thing for a few years now.

"As U.S. airports begin installing face-recognition systems to thwart terrorism in the wake of the Sept. 11 attacks, civil rights activists are rushing to decry the technology as ineffective and invasive."

"In the USA Patriot Act, the National Institute of Standards (NIST) is mandated to measure the accuracy of biometric technologies. In accordance with this legislation, NIST, in cooperation with other Government agencies, conducted the Face Recognition Vendor Test 2002. FRVT 2002 Sponsors and Supporters are: Defense Advanced Research Projects Agency, Department of State, Federal Bureau of Investigation, National Institute of Justice, National Institute of Standards and Technology, Transportation Security Administration, ONDCP Counterdrug Technology Assessment Center, United States Customs Service, Department of Energy, Drug Enforcement Administration, Immigration and Naturalization Service, Secret Service, Technical Support Working Group, Australian Customs, Canadian Passport Office, United Kingdom Biometric Working Group.

I included the long list of agencies because under Homeland Security they will undoubtably share databases. If you have been scanned, everyone has your facial recognition file and fingerprints. I tried to stand out of the camera view, but there was no good way to aviod walking past it. The customs guy did alot of typing when I came in, probably as it was my first time in front of a facial recognition camera. My girlfriend was practically waved through, but she had been though customs just a year ago, as so probably already has a file.

Will somebody please explain to me why every time some new way to do anything that would involve identifying people, it's an invasion of privacy? I mean honestly, why are you so afraid?

The freedom of assembly is what's at stake, and it in turn is essential for a free democracy. If the government can track the movements of innocent people, then it can monitor the organizations and associations (including political) that one is associated with. And if the government has the power to document the members of every rival political movement as it is forming, including all the other activities of the members, then they have the power to intimidate and crush it. (Don't believe me? Find a history book.)

Privacy from the government is a key component of freedom, because it places serious constraints on the government's power over the people. Without this, you can very easily become a subject rather than a free citizen.

Ever heard the term "panopticon"? When you know that someobody could be observing your every move and you don't know exactly when you are being specifically observed, your behavior will change to what you believe the observer wants. Every camera brings us one step closer. I know there is no expectation of privacy in public but I wish it was a person on every corner rather than a camera. What the camera sees has the potential to exist indefinitely, human memories will fade and disappear.

Surveillance soceity.

I wonder whether these scientists lose any sleep over how their research advances will contribute to the future of our societies.

I wonder whether these scientists lose any sleep over how their research advances will contribute to the future of our societies.

If scientists ever paused to think for the possibilities of potential abuse of their intellectual effort, progress as we know it would come to a grinding halt. Back to Neanderthal times...

It relies on the ordinary people to safeguard their societies from degenerating but that is an entire different subject (requires getting off the couch alot), and since I can already see the political-zombies approaching to offer their caned insight into the matter it's time for me to split...

Re:Surveillance soceity.

[ucblockhead]

Every technology has downsides. This technology clearly has pretty serious upsides. Do you wonder whether the inventors of the integrated circuit lost sleep over the contributions of their work to the surveillance society?

Re:Surveillance soceity.

[Thrip]

I think you're letting researchers off the hook too easy. There are a million things to research, yet many people choose to work on projects that have dubious implications for society. I mean, sure, there's a lot of gray area between searching for a cancer cure and weaponizing anthrax, but I see no reason to excuse scientists from at least asking themselves where their work falls on that spectrum, and whether what they're doing is likely to improve or damage our world.

Back to Neanderthal times... I'm afraid moving forward to Neanderthal times isn't any better. If we have slow down to go in the right direction, so be it.

Re:Surveillance soceity.

[maxume]

Name five technologies that you like. I bet I can name dubious implications for no less than 3 of them, especially if you make them different, rather than hiding behind fragrances(which can be used to make food of low nutritional value more attractive, or to shift the moods of shoppers so that they are a bit more spendy) or whatever, and relatively specific(because in general 'a cure for cancer' is a good thing, but not really a technology).

Re:in other news

[grammar fascist]

Right.

Recognition tasks are almost all inductive in nature, where performance on math is deductive. Human induction pretty well spanks machine induction at most of the things we take for granted - like recognizing and decoding faces, voices, speech, the sound of your walk, etc., etc., etc. The thing computers do least well is infer what bits of information are most important. We seem to excel at that.

Despite what the findings say, I stand by the faces thing. It sounds like the recognition algorithms got high-resolution 3D scans of human faces as input. Wake me when they can do as well as a human with low-resolution 2D scans.

That being said, it's great to see progress in this area. I can't wait until someone has to lop off my head and carry it with them in a plastic bag in order to break into my workplace. It's more grisly than taking a thumb, but much less likely to happen... I think...

Yep, it can back up any claim.

For example, dinosaurs co-existed with humans.

The problem becomes how do you "flash" an image at a computer. A computer has a perfect memory. So you can't compare humans and computers in this way. A computer could completely memorize millions of faces, or even all the faces in the world, given enough storage space. 6 Billion people x 1 MB (exaggeration) per picture is only 6 petabytes. It's a lot of data, but not out of reach. So if computers get good enough at recognizing faces, it could become a useful too in security. Think about the security guard sitting at the front desk of 20 story building. Do you think he could identify every person who walks through those doors. Would he know if you were just using a stolen security badge?
