I used to laugh so hard at those tv and movie scenes when they would "enhance" an image: https://youtu.be/LhF_56SxrGk https://youtu.be/LhF_56SxrGk I guess yest

I guess yesterday's science fiction is now our reality.
- palad1n 3y agoI think I've got a twitch now, when I think about this. How those stupid moviemakers would say, "enhance!" and I (along with many of my geek brethren) were like, "there are no more pixels, that can't be done!" And now it exists. "Enhance" exists.
- kyriakos 3y agoOr does it? If you enhance security footage to make a barely visible face recognizable it will make it but it won't be the person in the footage anymore.
- wood_spirit 3y agoIt would be really interesting to see what it upscales poor security footage to be when we know the people in the picture; how accurate was it?
- wruza 3y agoThe models usually bundled with ESRGAN don't enhance like CSI. They straighten lines and jpeg blocking a little and correct "subatomic" details, but cannot restore large areas like faces, objects, etc. It's more of an AI-flavored "Effects - Sharpen" than stereotypical "Enhance!".

- kookamamie 3y agoIt does not exist. The AI models generate "what could be" instead of "what was", i.e. they hallucinate heavily in upscale tasks.
- lostlogin 3y ago> It does not exist. The MRI scanner near you is potentially using AI to increase image signal, then to increase pixel count 4x (well, 2x in X direction, 2x in Y direction. Potentially also generating a slice between each slice in 3D datasets). If you turn off the AI and actually acquire the information, the scan is long, the patient moves and it is blurry. However if the patient is still, the non AI images look like the AI images. Disagreeing with it is sort of moot now - it’s in the machines and is running. It works well, I’ve been using it daily for a few years. All vendors have it - I use the Siemens product ‘Deep Resolve’ [1]. Their PR department undersells it, in my view this is a bigger change than the 1.5T to 3T transition.

- j16sdiz 3y agoThe scanner is faster because it collect less data. The image is sharper because it have more data. Where did the missing data came from? It came from the training data set, not the patient. No matter how good the image look like, it is not something from from the patient.
- spookie 3y agoThe better example of "Enhance!" still remains this piece of software: https://www.youtube.com/watch?v=19wgu5GZDhk https://www.youtube.com/watch?v=19wgu5GZDhk
- userbinator 3y agoIt just hallucinates the details now.
- pixelesque 3y agoYes - I can't find it now, but a few weeks ago I saw a demo website for some other upscaler with an example image of a picture of food, and it was pretty clear that the upscaled "version" was different bread than the original lower-res version, and things like herb "sprinkles" (oregano?) in the original became pine nuts or something in the upscaled version....
- NayamAmarshe 3y agoYes, I personally think it's false advertising. AI Re-painter is not AI Upscaling. I even received a review on Mac App Store saying Upscayl is worse because it does upscaling instead of repainting like Magnific.
- qingcharles 3y agoThat bread is from the front page here: https://magnific.ai/ https://magnific.ai/
- forgingahead 3y agoThe correct phrase should have been "Hallucinate!"
- holoduke 3y agoExcept that when you try to enhance the numberplate of a suspected killer you get a platenumber which is based on avarage noise and mqybe different than reality.
- NayamAmarshe 3y ago> I guess yesterday's science fiction is now our reality. That's actually what's written on https://upscayl.org https://upscayl.org, "From Science Fiction to Reality" haha
