Upscayl – Free and Open Source AI Image Upscaler for Linux, macOS and Windows

Why all the negativity in the comments here? Yes, sometimes it is extremely valuable to make a nice thin wrapper on existing tech. As a community, we can't always complain about the user interface of FOSS tools, and then when someone makes a UI, again complain that they haven't done anything or the size is large. Pick a side!

The app contacts Github&#x27;s CDN every 45 seconds. Is there a particular reason &#x2F; need for this behavior?<p>Tested on macOS with the following command:<p><pre><code> sudo tcpdump -k -i en0 | grep Upscayl</code></pre>

Why not use Real-ESRGAN directly?<p><a href="https:&#x2F;&#x2F;github.com&#x2F;xinntao&#x2F;Real-ESRGAN" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;xinntao&#x2F;Real-ESRGAN</a>

This UI wrapper doesn&#x27;t have any way to set options for upsample or tile size parameters. I also don&#x27;t see any way for it to set the model yourself.<p><a href="https:&#x2F;&#x2F;github.com&#x2F;xinntao&#x2F;Real-ESRGAN" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;xinntao&#x2F;Real-ESRGAN</a><p>The Real-ESRGAN page has links to additional uis to try out.

Nice to see one of these that can use the GPU on my Mac laptop out of the box - I just tried it after installing from the .dmg, it worked great.

I like video2x[1] for this, a nice simple CLI with lots of different options for different cases, (especially the anime upscalers) used it quite a bit, also played with realcugan-ncnn-vulkan[2] which has given me pretty great results.<p>[1]: <a href="https:&#x2F;&#x2F;github.com&#x2F;k4yt3x&#x2F;video2x" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;k4yt3x&#x2F;video2x</a> [2]: <a href="https:&#x2F;&#x2F;github.com&#x2F;nihui&#x2F;realcugan-ncnn-vulkan" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;nihui&#x2F;realcugan-ncnn-vulkan</a>

Would it be too difficult to add video upscaling feature to this? It&#x27;d really help with old videos.<p>I have videos I took on my Sony Ericsson w810i in the 2000s. The joy of being able to capture something animated on a small screen... I remember it used to show what song is playing at the top and I thought &quot;cool, it shows banners similar to what we see at the bottom of news channels&quot;! Would be great to elevate those videos to today&#x27;s standards.

Anyone compared it against Topaz Labs&#x27; Sharpen AI&#x2F;Gigapixel AI?<p>Which is better (putting paid vs open-source debate aside) in terms of result image quality?

I tried Real-ESRGAN but it seems to dream up slightly <i>too</i> much? Has anyone else had this problem? It tends to generate details where there shouldn&#x27;t be any.<p>Maybe I need to add some setting?

How does Real-ESRGAN used here compare to waifu2x ? I&#x27;ve had great success using waifu2x, especially for blurry artwork.

NCNN does work with just CPU. Just need a little bit more packaging.

It really does need a GPU. Tried it on a laptop with integrated graphics and it crashed completely. Didn&#x27;t even give a BSOD, machine just went dead and rebooted.

It&#x27;s just relabeled Real-ESRGAN. Real-ESRGAN is still a very good solution, but I don&#x27;t know if this project is contributing anything new.

Thanks for the great tool! Although i know how to use those models, this makes my life more easier!!!!

Could something similar applied to 3D scanner points cloud ? Would Real-ESRGAN work in 3D ?

This is awesome... I wonder if we&#x27;ll get something for video upscaling like this?

Another interesting feature might be image sharpener while maintaining the resolution?

&quot;Make the whole world use FOSS&quot;<p>At least they have realistic goals...

Was Upscail taken?
