It's only now that we fully realize how bad the depicted policing was in all those TV shows where they zoomed & "enhanced" the photo evidence.

Well, this does explain the disproportionate amount of actors that are arrested in CSI after reviewing the video evidence.

Think that's bad? Somewhere there are cops using this thing for real

  Indeed, that may very well be the case. I know we have all seen mugshots of persons of interest that are pulled from CCTV and have less pixels than minecraft avatar faces, along with the colour pallet of a ZX81/C64. How AI and visual processing adapts too face-coverings is sure going to be interesting in many avenues, let alone humans.

    Often it doesn't take much for someone who knows a suspect to recognize them from a few blurry frames of video or a drawing. I am constantly surprised by how extremely bad surveillance cameras are and also how they still sometimes make it obvious who was or wasn't at the scene because of minor (and slmetimes not so minor) details in clothing, shoes, face or gait.

      That’s the 5G conspiracy theory “they” don’t want you to think about: 5G will allow pervasive surveillance with quality much better than today’s potatocams

I suspect Ryan Gosling might be the perpetrator in many future crimes! Almost as scary as the prospect of an AI that can "predict future criminals" based on their facial features!

Not quite. Super-resolution from face prior is probably a bad idea if you're looking to identify someone, but super-resolution from video works. It doesn't make up information based on what it expects the face to be, but collects and aggregates information from multiple frames.

    Literally the first Google result for super-resolution from video: https://paperswithcode.com/task/video-super-resolution https://paperswithcode.com/task/video-super-resolution
    - murbard2 6y ago
      Lots of neural-network approaches for this which work quite well but are also likely to learn priors from the data which can introduce tricky issues for police work. There are however approaches which aren't based on machine learning at all, for example https://www.di.ens.fr/~mallat/papiers/whitepaper.pdf https://www.di.ens.fr/~mallat/papiers/whitepaper.pdf

      IMO it’s still nice to provide links. For one, readers won’t know ahead of time if it’ll be the first result or not. Aside from that, search results can vary from person to person what with Google filter bubble. And on top of that, if I find a source I still don’t know if it’s the same thing that was being talked about. Worst case I might find a bad source instead and then disregard the information because the source I found for it was bad while there existed good sources for the information unbeknownst to me.

      Yeah thats not a source at all. Its a collection of paper on the relevant topic. The claim of the parent comment was > but super-resolution from video works. It doesn't make up information based on what it expects the face to be, but collects and aggregates information from multiple frames. So I was simply interested in hearing where this claim comes from. Has any of these papers mentioned that this is the case? I briefly went through some of them but did not see any such guarantee.

Actually I felt a lot like I was using just that Software when I enhanced a low res picture with this software. Give it a try, it works absolute magic.
