All of this surveillance with cameras from china articles has me highly skeptical. Can CCTV quality cameras really be used for on the fly person recognition, including determining if an identified student is 'focused' or 'dozing off'?
I keep thinking that this type of surveillance from China is all smoke and mirrors, to make it seem like they have more of a lock down than they actually do. Even if an automated person recognition/mood judgement system was 99% accurate for a public CCTV camera, that's 10 false positives per 1000 people, and consider how many people it would see a day. But I don't work in image/video processing, so idk. But I think it's harder than identifying crosswalks, fire hydrants, and storefronts.
- bubblewrap 8y agoIn a classroom, it only needs to recognize 30 people. That seems doable. Car makers also claim to work on detecting dozing off of drivers. What about it should be impossible? Detecting if eyes are open or shut sounds doable, unless everybody is wearing sunglasses.
- larkeith 8y agoAll it needs to be is smoke and mirrors, with a bit of human oversight to give it credibility. Even if it only has a 50% accuracy, an administrator can review the flags and take action, discouraging that activity for everyone. The same applies for identifying dissidents.
