Some years ago (around 2004) I think Intel showed off a new best of class image uprezing software, that took something like 100 hours to uprez one frame and bring out new detail. With modern GPU processing maybe you could get a reasonable rate. In the late 80's and early 90's, fractal compression was the go, and it could automatically scale the picture and bring out hidden detail (apparently). Also in the mid 2000's Intel showed off 2D to 3D converter software, concepts I had come up with ears beforehand as part of my other research. What they might have figured by now is that combining this 3D conversion with image restoration, gives a very powerful restoration tool.

It is a matter of which methods you are using and how much processing power. You might be unlikely to produce an credible cinema like SHD footage from a sub SD security camera (without artificially filling in details) but there was a company using a farm of powerful servers to restore early century decayed cinema footage to normal quality, in a fashion similar to my previous ideas. Even camcorders these days have caught up and are comparing subsequent frames intelligently to remove unwanted noise. It is just a matter of systematic processes to derive the data.

I only have a meager knowledge of this side field from my main fields. So I imagine there are even better tools out there available to various levels of government agencies, but most of the time on TV it is probably just convenient to use sensational tv rubbish, and most police stations might have access to, or download, common tools over the internet, and departments maybe progressively something better going up the hierarchy.

Aw, come on. We have all seen the FBI (the TV FBI, anyway) blow up the corner of an image from a security camera into a fully detailed photo of a suspect.;) And get plate numbers of cars from satellite photos.:laughing-smiley2: Just imagine what the real Feds can do with all the secret stuff they don't tell us about. :eek:
IMO, enhancing TV is one of those "why bother" items.

You're joking ;) ? Haven't you heard of adaptive optics, or that in the 80's before skylab re-entered, they used computers to process pictures of the rivets on the thing. With time sequenced pictures, on top of these other things, you can obtain much higher resolution than the original (even if it is not one of the HD security camera feeds) (though it has limitations). If you wanted to get really fancy you could illuminate the target with a laser from space which should be able to scan it at a frequency offering minimal interference from the atmosphere. It should be possible to design such a system that could scan atoms (while tattooing you) (now I have talked too much, got stop giving these guys ideas ;) ).

Holy crap, FREE TATOOS? Well not really, I guess my tax dollars will be used for this little adventure. Looks like they could use this kind of system at the airports, you know, to speed up the line a little bit..:)

Remember back in the late fifties, you could order these X-Ray glasses off the back of comic books. I hated that, cause I couldn't afford 'em. It showed a guy looking through the dress of a young lady. We didn't know they were bogus, we just wanted them. Now they got the technology I still can't afford it, but now, instead of using it for entertainment purposes,i.e. TV, Movies, the government is checking us out at the airports. Go figure. So I guess what I'm saying is some technology needs to be destroyed before it's abused. It's gonna get better...
