Upscayl

Dev's current description of Upscayle "AI": "Free yourself from all the constraints. Upscayl is now everywhere! No more long loading times, hardware issues or quality compromises! . . . With state of the art AI, Upscayl helps you turn low resolution images into high resolution. Crisp and sharp! • Upscayl anywhere, anytime, any device • No GPU or hardware required • Face Enhancement • 10+ models to choose from • 5x faster than Upscayl Desktop • Video Upscaling • Commercial Usage • 5+ Modes • Fully Customizable • Free and Open Source" - - Despite the above, the FAQ states: "Q: Do I need a GPU for this to work? A: Yes, unfortunately. NCNN Vulkan requires a Vulkan-compatible GPU. Upscayl won't work with most iGPUs or CPUs. But hey, no harm in trying ;)" - - IOW: CONFUSION and GUESTIMATION, not unlike the general HYPE that is current "AI". <-- As such, be glad it's free. Consider it BETAWARE, IMHO. Be certain to keep your SOURCE image! THAT is what's accurate, not any AI reinterpretation.

The description of this software at this point is disappointing and partially wrong. And of course, so-called "AI" isn't, and what you get is a mashup of stuff from its database that it interprets as an 'improvement'. If you're using this software to tease out detail from a low resolution picture, good luck. That's not what this software is for and is not what it does. - - I'm going to make a followup comment providing a description of the software according to its current home page. - - Again, never count on "AI" accuracy. It's an reinterpretation of input that is limited by its database of information.

app does not do anything this Message pops up: DECODING ERROR=> This image is possibly corrupt or not supported by Upscayl. You could try converting the image into another format and upscaling again. Otherwise, make sure that the output path is correct and you have the proper write permissions for the directory. If not, then unfortuantely this image is not supported by Upscayl, sorry.

github never checks what system app works, probably app Developers are Micro*hore Widows Developers! This is 2nd app my github this Week That is junk on MacOS High Sierra. (10.13.6)

I have a 2017 27" iMac OS 10.13.6. The sad truth is that this doesn't do squat. I go through steps 1 - 4 and click ”upscayl” and all I get is a “DECODING ERROR =>”. IT does the same thing with jpeg, png, tiff, and eps files. Useless!

Wow. Amazing. Works well with M1 Mac. Seems to over-sharpen a bit on the images I tried, but a great, quick way to upscale low-res images. Highly recommended.
