Denoise Software like Topaz?
Posted by AlexMullerSA@reddit | linux | View on Reddit | 14 comments
Just moved from windows to CachyOS and iv been fine with gaming and basic photo edits using Rawtherapee. Mostly what I am missing from my workflow was using Topaz to denoise images that were shot at higher ISO. Rawtherapee sliders kind of just smooths out the image and isn't comparable to the Ai denoise filters. Is there any alternatives to Topax/DXO/Lightroom denoise? or perhaps a way of getting Topaz to run via wine?
I would appreciate any input.

On Linux I would test a few categories rather than look for a 1:1 Topaz clone.
I would avoid using a generative upscaler as the first denoise pass for high ISO photos. It can make noise disappear, but it can also invent texture. For portraits especially, compare eyes, hair, and skin at 100% before trusting it.

What about DarkTable?

Ill have a look again, the interface was extremely confusing for me, but as far as I know its also just a 'filter slider' that smooths out the image.

Not very good results, and UI is just confusing.

I was pretty thrown by the dartkable UI initially too, so I opened an LLM and told it which version I was using and just started asking what different things do and how to set it up for a beginner experience. Helped a lot and really fast

Then if you are looking for an AI denoiser, what about just loading it up into Stable Diffusion? I've seen some denoisers out there.

dont know anything about it, will look into it.

I am using this software in command line: https://github.com/cszn/SCUNet

I use a program called Upscayl it's got AI upscaling and denoising features. Kind of simple but worth a look if you are looking for AI based photo cleanup.

I am not aware of any open source software for any OS that is remotely comparable to these, especially something like DxO's thing which works directly with RAW files*.
The closest that I am aware of are various "Multi-Frame Super-Resolution" implementations, which I believe are basically attempts at implementing computational photography; you can find some papers and projects on GitHub.
*It's really impressive; I did a test where I took a noisy JPEG and turned it into a synthetic RAW file (by creating a CFA from the pixels) and adding noise via random offset to each CFA pixel. DxO PureRaw 4 nearly perfectly removed the synthetic noise and left the original noise from the JPEG. I tested the denoiser from Affinity Photo 2 (which seems fairly good), and when given the synthetic RAW file, it removed both our synthetic noise and the noise from the JPEG (i.e. would incorrectly remove noise-like details).
Note: I am not affiliated with DxO. Their software sends a bunch of telemetry which can't (as far as I know) be turned off. I recommend blocking

you can try raw therapy software.

That looks nice, a total variation denoiser I'd guess?

Showfoto, a very complete editor developed by KDE.

not bad, thanks for the suggestion!
