Hm, isn't it possible to wear clothing that AI can't see?

So called ai is likely opencv and a model slapped on top. So to determine what it can and cant see you can play a bit with opencv to see how feature detection and extraction works.

  Talking about feature extraction reminded me of these military exercises where they fooled a DARPA robot that was meant to be doing surveillance. The military reached their target by moving inside a giant cardbox! Snake style!

It’s very model and hardware dependent

There's active infrared clothing which can partially protect you from cameras in general. E.g., a cap with 10 LEDs or so will probably hide your face most of the times.

  That would probably overload the sensor so that your face would be less identifiable, but you would become instantly "that guy with the glowing face" which would make you much easier to track. Unless of course everyone starts using them, but that's another story.

  I've wondered about doing this, just to make the point obvious that I don't like being face-tracked everywhere.

If I cared, I'd probably wear a couple near-infrared leds and blink them in a random timing pattern and combinations of lights so that cameras which pick up a little NIR would effectively be blinded.

    And if more than one person tries this, then: > random timing pattern and combinations of lights is an FFT away from being a unique tracking ID for that person! :).

There is no such thing. There were a few articles in press about such clothing, but it doesn't work. If a human can see you, an AI can just as well - with modern tech. The only success was with highly controlled environments, and specific models - but these are extremely unlikely to scale to proper models.

  I wouldn't expect most companies to use "proper" models at this point; some will, but for most (especially when used for mass-surveillance) I'd expect low computational cost models. This will change over time, but just for the moment we do have an AI bubble exceeding the supply of people who can make good AI.

    Even then such attacks only work under very controlled conditions and do not generalize across models. You might be able to fool one vendor/generation, but not all the others.
