So, basically, this is the thing in a crime detective movie where the forensic analyst is looking at a terrible pixelated surveillance camera still and says "enhance," and the computer magically increases the resolution to reveal the culprit's face.
Just another entry on the "things that are supposed to be impossible that convolutional nets can do now."
- dankohn1 10y agoHere is the ridiculous Let's Enhance supercut that all just became realistic: https://www.youtube.com/watch?v=LhF_56SxrGk https://www.youtube.com/watch?v=LhF_56SxrGk (Created by the super talented duncanrobson)
- eejr 10y agoyup, to certain point! there are information theoretic limits though. You can fill in information, but there will be biases to a certain point. in this case defined by the dataset. if the "enhance" is too strong, we should be careful with what we do with the results in forensics. but man, it can make your internet pics look smooth! :) thanks for the comment!
- paulsutter 10y agoIf you have multiple images of the same scene (for example, from video frames), you should be able to use information across frames for a true enhancement?
- eejr 10y ago;) sshh! don't say that too loud yet. but, remember our names...
- microcolonel 10y agoSo you're saying this could be useful for stereo imagery and video? ;- )
- CamperBob2 10y agoYes, and it's almost ridiculous how well that can work: https://www.youtube.com/watch?v=ONZcjs1Pjmk https://www.youtube.com/watch?v=ONZcjs1Pjmk
- nitrogen 10y agoThis (overenhancement) was a minor plot point in Crichton's novel Congo, IIRC.
- Eliezer 10y agoAnd that's how that guy whose face appeared a few times in ImageNet became the world's most wanted terrorist, on the run for thousands of crimes.
- nullc 10y agoDing ding. But good luck convincing a jury that a maximum likelihood decode from a few grainy pixels wasn't reliable when it gave a crystal clear output.

- taneq 10y agoI bet he's hiding out with that lab tech whose poor technique lead to their DNA being in hundreds of crime scene samples.
- duaneb 10y agoI imagine you'd want PII erased from the training set, but the danger stands.
