Didn't really know how to categorize, bit of a question/discussion/curiosity, so I put it here.🤷

Just today I read an article that stated about the Netherlands, where the police will use an "AI surveillance camera" (yey buzzwords incoming 🙄, but it would actually make sense(?)🤷) to detect and punish drivers, holding a smartphone. Pictures without smartphone shall be deleted. How would this system work without having non-smartphone pictures? It needs to build a classifier, doesn't it? (To be clear, the system only reports those images to an officer for further analysis and actions.)

I mean let's consider that the images are somehow pre-processed, then some convolution(s) for feature extraction, then maybe some more intermediate steps and at the end apply the results on a classifier. How would that classifier work? Would a probability between 0 and 1 suffice? And if so, report those from 0,5 and above? Or would there be better techniques?

    It doesn't need to store any *more* images.
    Presumably they already have tons of traffic footage which they're using to train the detector, my guess would be that they just use a deep net object localisation algorithm like YOLO which also outputs confidence values and is fast enough to run realtime. If the confidence is more than a certain threshold the frame gets sent to the authorities I guess with the location of the phone marked and stuff (because YOLO can also find object positions, not just detect them).

    I know the UK was/is looking at a similar sort of idea but that one would listen out for signals from the phone and disregard any which also had Bluetooth too. Not sure how feasible it really is. I guess it would also need a human to verify it was the driver using the phone, not another occupant.

    I'm dutch and it's currently in a testing phase on two highways.

    I hate surveillance but phone usage in the car is so bad that I approve of it.

    I'm tagging @linuxxx because of privacy and being dutch

    They're training algorithms to detect it when someone is holding a phone to their ear in a car or truck. The cameras for this have been in place for a while as far as I'm aware.

    I think they're actually applying a form of AI and machine learning to this, involving a buzzword doesn't mean that the buzzword is false in this context by default.

    A picture is taken and if the algo detects (possibly) someone using a phone while driving, it is stored and send to a human being to be verified.

    As long as they don't store the images of people not using a phone, I'm fine with it (because fuck people using their phones while driving), otherwise no so much (the government doesn't have a single reason to store those images).

    I think that the issuing tickets/punishing people should be done through review only.

    Australia already has this in trails.

    it picks you up even when the passenger has their phone out or you have your hands near your face.

    @C0D4 heard that in china there were already people that were fined because a camera tracked them when they actually just scratched their face.😅

    @cb219 that's probably where this one came from. It had a lot of false positives, but then this makes sense for a pilot "AI"

    @C0D4 gotta start somewhere 🤷
    would be interesting to see smth similar be even considered in germany, where these things are almost impossible to realize.🙄
