If like me you're using Real-ESRGAN-ncnn-vulkan [1] and are curious what upscayl-ncnn CLI [2] changed from it, there's not much and nothing substantial [3]. Not a criticism, just wanted to learn whether it's worth upgrading to for a CLI tool ($subj is a separate GUI app based on it).<p>[1] <a href="https://github.com/xinntao/Real-ESRGAN-ncnn-vulkan">https://github.com/xinntao/Real-ESRGAN-ncnn-vulkan</a><p>[2] <a href="https://github.com/upscayl/upscayl-ncnn">https://github.com/upscayl/upscayl-ncnn</a><p>[3] <a href="https://github.com/xinntao/Real-ESRGAN-ncnn-vulkan/compare/master...upscayl:upscayl-ncnn:master">https://github.com/xinntao/Real-ESRGAN-ncnn-vulkan/compare/m...</a>
I used to laugh so hard at those tv and movie scenes when they would "enhance" an image: <a href="https://youtu.be/LhF_56SxrGk" rel="nofollow">https://youtu.be/LhF_56SxrGk</a><p>I guess yesterday's science fiction is now our reality.
I tried this out back in December. It is very straightforward. Would recommend for anyone who is testing the waters and just trying to start exploring the various tools.<p>From my understanding though, the quality is pretty far behind that of the cutting edge. A friend recently recommended Topaz to me, but that isn't open source.
UpScayl is great, I use it a lot for work. Upscaling low-res graphics and illustrations for use in graphics in a pinch, upscaling portrait photos of people for print and photoshop… upscaling old copies of things for editing purposes, you name it.<p>It’s not perfect but no alternative is. Bloody useful though.
upscayl is very approachable, but lacked many features i needed. i ended up using <a href="https://github.com/AUTOMATIC1111/stable-diffusion-webui">https://github.com/AUTOMATIC1111/stable-diffusion-webui</a> after upscaling became part of my regular workflow, but for someone who just needs a few images enhanced, it's an ideal tool.
Are there any models out there for cleaning up an image, not just upscaling? I have a bunch of old photos taken on early low-res point-and-shoots that have JPEG artifacts etc and this seems like something a modern model could easily be fine-tuned to resolve, but every few months I look around and have yet to find anything
Unfortunately, for video, nothing I've seen yet has matched the quality of Topaz Labs' (paid) tool. Clarity and consistency always seem to be an issue with other implementations. If love to be proven wrong because I have a project that's stalled due to the low quality/resolution of the source.
Another upscaler, for images and video<p><a href="https://github.com/k4yt3x/video2x">https://github.com/k4yt3x/video2x</a>
Is there an upscaler which looks at other similar photos we took?<p>Been looking for The Magic Photo App, reverses motion blur, can interpolate multiple photos to unblink some eyes and select best photos of a scene.
I wonder if image upscaling is actually reflective of a greater disease in society: we are exceptionally obsessed with holding onto everything. I mean, my God, if the situation comes down to a desire to upscale an image, just let the image go.
