What worries me is that COTS photo equipment increasingly comes with these algorithmic retouches that "over-represent" the data - or, put another way, bake its own interpretation into image, in a way that cannot be distinguished from source data. It's nice for a casual Instagrammer, but then a lot of science and engineering also gets done using COTS equipment. I worry that at some point, a lot of money will be burned…

I did a web search for "cots" and learned that a cot is... > a small usually collapsible bed often of fabric stretched on a frame But in this case, COTS is apparently... > commercial, off-the-shelf In other words "photo equipment" or "consumer/retail photo equipment." Upon further reading[0] it seems odd to use the term here, but maybe I'm misunderstanding something. It's often used for software and has a key phrase.…

It’s a common acronym in the tech world. I’ve usually used it in the context of a “buy-or-build” conversation about software (e.g. “most businesses are best off using COTS applications than doing custom development” - that sort of thing). But the acronym means what it means, so when OP talks about COTS camera gear, it makes sense to me.

Yeah, a monthly payment forever is ridiculous...

I really don't see 10$ a month for a tool as advanced as photoshop as outrageous.

I think it is $21/month: https://i.imgur.com/q5BSDWI.png

Did you read that article? That wasn't an OCR issue it was an image compression issue.

Same thing in a way. OCR does lossy compression from pixels to text. Both could do similar mistake for pretty similar reasons.

Possible practical application: can anyone upscale the beatles abbey road cover to a higher resolution please? I've always wanted it as a wall poster.

What's the point? If display resolution was way higher than capture resolution than I could see it. But the opposite is true. A 4K display is 10 megapixels, most entry level cameras are in the region of 20-25mp.

You might want to crop in to that photo.

This seems highly relevant as to what is actually going on: http://www.johncostella.com/magic/

That's an interesting article, and relevant in the sense that the "magic kernel" can be used for purposes of super-resolution, but Adobe is using a fairly different approach. Instead of using analytically-derived functions Adobe is using a deep learning model trained on a large dataset of Low resolution-High resolution image pairs. The details are propietary, obviously, but it's likely similar to various deep learning superresolution algorithms in the academic literature. (Some more info here https://blog.adobe.com/en/publish/2021/03/10/from-the-acr-te...)

I was BLOWN AWAY by this STUNNING new technology! The brilliant minds at Adobe have done it yet again. This changes everything. Adobe (ticker symbol ADBE) keeps innovating and defining the very future of creative imaging software. From the widely loved Cloud platform and easy rental model to the file formats which are so packed with features that each new update takes the competition possibly years to fully reverse engineer for interoperability. Probably because their engineers aren’t nearly as good!

Yes my jaw hit the floor when I saw this headline.

No there certainly is a chance for ML to improve here. Let’s take the classic example of enhancing a blurry photo to get a license plate. Humans may not be able to see much in the blur, but an AI trained on many different highly down-res’d images could at least give you plausible outcomes using far less data than a human brain would be able to say anything with confidence. You wouldn’t hold it up as the absolute trut…

> Let’s take the classic example of enhancing a blurry photo to get a license plate. That's not the same as fabricating information, though. A blurry image still contains a whole bunch of information and correlation data that just isn't present in a handful of pixels. This is not super-resolution, but something different entirely. Super-resolution would mean to produce a readable license plate from just a handful of…

I was simply pointing out that AI enhancement to find details otherwise not possible by humans that could be useful/accurate is very possible, and I don’t think you refuted it.
