It is being called “cv dazzle” to defeat facial recognition like that used by Facebook.

I’m wondering if anyone has experience using this in protest, or if you’ve heard local coverage about it?

    It wouldn’t work on thermal imaging cameras with AI facial recognition that’s specifically trained to see past facial obstruction.

    They have the ability to recognize faces through sun glasses, mask, medical and skimask, paint or makeup and certainly this. A full facial mask with aluminum would work.

    Ironic but not really. That’s the old joke about a tinfoil hat. That’s what the joke refers to. Aluminum blocks radio frequencies. Including infrared (thermal image in this case)

          I work in this field. No such thing exists. Thermal Imaging, including FLR, doesn’t have the contours in 2D images needed to profile anything at all. There is no such thing as a depth ranging thermal camera sensor with complex stereoscopic images that can service contours for inference. It doesn’t exist.

              Your take on this is inaccurate, and this is not “facial recognition”. This is pattern recognition, and shoddy at best from the description. It’s using converted 2D imaging data with heat sensor data, and reduxing the resolution down to another 2D map, and ATTEMPTING to make a match. This is what we would call “fuzzy” recognition, and is not accurate at all. Fuzzy inference takes any range of accuracy as a success, meaning if it gets it right 5% of the time, it’s considered accurate.

              Bottom of the barrel bullshit that doesn’t work. Don’t even take my word for it, you can look up this same pipeline model of inference in countless GitHub repos that the original work came from and understand why.

              Here’s an example:

              • Person 1 goes for a run, then turns direct to FLR camera
              • Person 2 who looks similar, but 50lbs heavier walks out of their house and walks towards camera
              • 15% match on inference

              The military would consider this a detection.

              YOU on the other hand are talking some crazy conspiracy theory noise about how these cameras are used in crowds and can differentiate using heat detection maps on people wearing face paint.

              NOT HOW THAT WORKS

              This is saying they can map thermal to known faces. But this is far from being able to read faces through materials. Thermal/infrared doesn’t provide that kind functionality, at least to my knowledge the signal would bleed into the mask. It could work for glasses or maybe thin masks.

                Look, the government lies and lies some more. This would be damning if people realize they have this stuff. That article is from 2018, they just aren’t telling you or anyone else over a megaphone.

          Can you just post all the applicable research in an easy-to-follow format that I can copy/paste into an angry email to someone? Cool.

          Otherwise you’re a Nazi somehow.

            Use an search engine. Why do i have to do your homework? Do i have to tuck you in at night and read you a bedtime story too? Also you calling someone a Nazi because they didn’t do something for you is a highlight of your dullness. The irony
