Otherwise I will stick with the avs way, coz there is a small batch to go, less than a 100 images.Meditation has ancient roots вЂ“ so does Sattva.ДЄuthentic, deeply profound and drawing from Vedic principles of meditation that millions of people have benefitted from for thousands of years, the meditations, chants and mantras on Sattva are delivered by Sanskrit scholars who have mastered the subtle inner workings of the mind. If it is much better than what I get using avs, I am going to pick the approach. I am going to try the methods you suggested in an image software, see how clean I can get. It is really amazing that you find out so many things that I want to do, but not mentioned in the first post.

Though it's not free it has a decent trial functionality and you can always search for the free alternatives of it. Still, for best results I would recommend applying FDF before the conventional denoisers, otherwise you'll often be left with lots of moire remaining in the image or you'll have to use extreme noise removal presets and lose the details.ДЄs for a followup general denoiser for images I can recommend NeatImage.

Keep in mind, though, that it's still a long manual process and even after removing most of the noise noise you'll be left with whatever random noise there was in the image. I wrote a manual for that tool in application to scan retouching. Here I can suggest a decent free alternative to photoshop plugins - Image Analyzer, which, among other things, has a special tool for editing the frequency spectrum - the Frequency Domain Filter. Considering that you're probably using a denoiser like Waifu2x without GPU acceleration (since it take 5 mins per image and the AVS ver indeed doesn't have it), you're not going to do batch-processing anyway.

It would make a lot more sense to use a specialized image editing software here. At some point I even tried to write a JS helper for it that would at least allow the user to select the areas with a mouse and generate AVS based on that as well as generating a way to import multiple images that have a slightly different size into a single video stream, but's still not very convenient. The only upside of doing it in Avisynth is batch-processing of loads of similar scans taken from the same source, because then the FFT discrepancies would be the same and it'll be enough to configure the filter once, then follow up with a denoiser as well. I only used DeFreq, it's tricky to use since you have to describe the FFT areas for removal in text form. If you really want to do it with Avisynth there are filters like DeFreq or Vcmohan's FFTQuiver (not sure if that one exactly, he has loads of various scripts). I used to deal a lot with scans so I can probably make a few suggestions here.ДЄs mentioned earlier this is a moire/screen effect, unlike the film noise it has a couple of fixed frequencies which makes it possible to remove it using those frequency peaks on FFT, instead of going in blindly. Now I remember that a long time ago I read about noise removal in imagemagick.Д«uilding imagemagick from source with fft support.Д¬reating spectrum mask from the phase and magnitude of the image.ДЇred's scripts collection is really a big one, I think it is enough for me to spend a few nights. Thank you for your effort for gathering these information!! Perhaps can access GIMP using similar methods(dont know, never tried it).Д®DIT: This guy has a lot of ImageMagick scripts, think we used some things from there, dont know if anything of interest.Д®DIT: Heres an interesting one if VideoFred is watching:- Д®DIT: Above linked scripts run under bash on linux, but note below (if you can find some descreen stuff for that, there is some IM stuff for creating halftone/screening, also think Martin53 did something to create screening in AVS). You can do a D9 search on POSTS(Not Threads) for 'Mogrify', for AVS writing/reading images for ImageMagick processing.
