Japan's NEC Corp Says New Facial Recognition System Isn't Stopped By Masks (mashable.com) 36

Japan's NEC Corp. says face marks aren't an obstacle to its facial recognition tech. Mashable reports: The Japanese company claims its new facial recognition system can identify people with face masks in less than one second, with an accuracy rate higher than 99.9 percent. The system works by closely examining the parts of a person's face not covered by a mask, such as the eyes and surrounding areas. It does require the person to submit a photo in advance, though.

The idea is for the system to be used at security checkpoints in office buildings, airports, etc., so mask-wearers can go through without removing their masks. NEC is also testing the technology out for automated payments at an unmanned convenience store in the company's headquarters in Tokyo. The company has sold the system to Lufthansa and Swiss International Airlines.

    Now people can just wear a full football helmet and Guy Fawkes mask over their cloth mask. Identify that.
  • Are they up or down ?
  • Are we talking about specificity or sensitivity? Being able to recognize that two faces that are the same are the same is a whole lot easier than rejecting other faces that are slightly similar.

      Define the use case. If they are selling to airlines then presumably it's identifying passengers. How does the airline get a known actuate photo of you though?

      • Well, how it's done today is, you hand them a photo and say, "I look like this, see? It says 'driver's licence' so you know it's legit."

          Last time I flew with Lufthansa they didn't check any photos. They made sure I had my passport with me (so they didn't have to fly me back home) but did not open it.

          That was over a decade ago I think, maybe things have changed now.

  • You insufferable totalitarian pieces of shit.

    Will be a nice time for you in prison, when the totalitarian pest is getting the justice of a nation of law.

    The system uses AI so it isn't even necessary to see a face to recognize it.

  • First of all, how would AI differentiate between someone who wears glasses and someone who does not wear glasses. Glasses also distort the faces/eyes. If someone submits picture without glasses and will AI detect that person when s/he does not wear glasses?
    • More sampling data or a better AI model. Like a photo with and without glasses may help. But with any decent AI, they might recognize you similarly to how a human might recognize a person with glasses that may have previously been absent from their face: via inferring from the distorted or alternate features.
      • According to the article, sample size is one. Even with OpenCV or other image manipulation software out there, you can only do so much.
        • OpenCV is a fairly basic image recognition framework that is used ubiquitously. Nowadays with more advanced AI models, however, it is usually only implemented to simplify say converting images into grayscale pixel arrays, if used at all--in other words: preprocessing.

          I get the idea that they're probably not using "just" OpenCV or some other image manipulation software for their facial recognition. And before underestimating the potential of AI, Two Minute Papers [youtube.com] is a great channel for discovering some leadi

    • Wow, was the AI model trained by Lois Lane??

  • How lucky for NEC that they can cash in on their technology!

  • We saw this during 2020 with Cisco's name labels and facial tracking on their devices. Worked pretty well during COVID, both for auto zooming and identifying the person to show their name.

  • The technology promises to revolutionize police work. Already it has identified a team of bank robbers in record time. Anyone knowing the current whereabouts of Bugs Bunny, Abraham Lincoln, George Washington, or James T. Kirk is urged to call the police.

  • Facial recognition is NEC's claim to fame in AI and they were a top speaker at a Japanese AI conference discussing it. Actually I met their project lead a couple times at conferences.. he was very careful about what he said. They have won international awards for it, and became a poster child of AI for the Japanese government's AI push.

    So it is tough for them considering the slew of regulations from cities and schools who do not want facial recognition. (Have to say I also don't like it, but on the other hand it is fabulous on my iPhone while the fingerprint sensor on my Mac sucks especially in winter and with disinfectant use.)

    That said, NEC did show once that they are or will be selling sensors to be located next to doors in an office building. As you walk by, it captures half of your head in 3D as well as photo so it is really accurate. I suppose it would replace the security card on a lanyard. As far as recognition while wearing a mask, this use case would cover it and I didn't see it in the article, but potentially they might use 3D capture / bone structure analysis and even posture / gait analysis, height, or laser telephoto of retina for all we know! There are things they could be checking to achieve the goal of identifying masked wearers and the system I just described might be the one they are talking about.

    Maybe their existing system can handle it, or they put more preprocessing into the shape and size of the head. Having a sensor from above to capture skull shape without being fooled by hair style might be an idea. As far as glasses, they ask you to take them off. Whether or not their AI can deliver 95% accuracy while wearing a mask is just a matter of their sensors and algorithms, probably likely I mean you can do the same with your mark 1.0 eyeballs right? So a computer can do it too, the question is how little hardware can they get away with applying to achieve it.

    My only surprise is that submission of a single still photo would be enough to train it. My guess is that Coronavirus is a major wrench in their plans, so making it work for surgical mask wearers, even with less accuracy, is critical to their product. All the silly comments about bike helmets Guy Fawkes masks are plain silliness. The world is not all as insane as the U.S. and NEC's product plans are not aimed at dealing with such idiots who would never be put in front of the product in the first place.

  • The 99.9% is probably for Asian people...

      It's pretty much the same. No mask, no mask, no mask, no mask, no mask. 99% accuracy.
  • I worked on this in years past.

    They are most likely not talking about identification, but rather verification -- verifying whether you are who you say you are, a much easier problem. Even then, testing has probably been done on only a small number of not very diverse people.

No spitting on the Bus! Thank you, The Mgt.
