ArgusMagnus Posted August 24, 2015 Share Posted August 24, 2015 (edited) Download: https://forums.getpaint.net/topic/32337-argusmagnus-plugin-pack-20181019/ (Copy the file "ArgusPDN.FFTEffects.dll" to the "paint.net/Effects" folder) This Plugin contains 4 effects related to Fast Fourier Transform and Signal Processing in the Frequency Domain: 1. Transform->Fast Fourier Transform: Transforms either intensity image or one of the channels (R,G,B ) to and from the frequency domain. The transformed image contains the magnitude information in the R and G values and the phase information in the B value (which basically means: don't change the B value of any pixel too much are at all if you want to get a meaningful result when transforming back). If you want to get a meaninful result when transforming back, there are two limitations: 1. Don’t change the B component (the phase information is important), 2. Non-rectangular Selections won’t work. 2. Signal Processing->Low Pass Filter: The same as using the transform effect, removing (setting to black or transparent) all pixel outside a rectangle around the center and transforming back only this is faster, more accurate (less information is lost) and easier to control 3. Signal Processing->High Pass Filter: The same as using the transform effect, removing all pixels inside a rectangle around the center and transforming back (again, faster, more accurate, easier controlled) 5. Signal Processing->Band Pass Filter: Combination of Low and High Pass Filter. Example: FFT Example images (high pass filtered, adjusted and blended together): The plugin actually uses the FFTW library (fftw.org), I have not written the transformation code myself (mainly for performance reasons) Edited October 19, 2018 by ArgusMagnus Added links to zipped DLL of Null54's updated version 1 Quote My batch Image Processor: https://imagenator.codeplex.com Link to comment Share on other sites More sharing options...

I took x64 DLL from x64 folder & deleted all other dll and folder and from from native Binaries. After putting dll in X64 folder in NativeBinaries. Now it is working fine. I placed DLL.

Rick Brewster Posted September 4, 2018 Share Posted September 4, 2018 Just a heads up, this plugin will not work in the upcoming Paint.NET v4.1 update. (see here: https://forums.getpaint.net/topic/113153-paintnet-41-beta-build-6808/?do=findComment&comment=548571 ) The reason is the use of PointInt32 which has been renamed to Point2Int32. I'm also planning on moving that type, and others (e.g. RectInt32), into a different namespace. So, I'd advise against using it for now.

null54 Posted September 18, 2018 Share Posted September 18, 2018 I recompiled the plugin for Paint.NET 4.1.1 using the source code @ArgusMagnus posted. Changes: Added a replacement PointInt32 structure to ArgusPaintNet.FFT.

Mighty Posted December 11, 2020 Share Posted December 11, 2020 I just started a thread and someone pointed me at FFT. I found this plug I found this plug in. But, when I use it, I get all blue or all black. I just searched, and I do have a copy of libfftw3-3.dll. It came with Inkscape, and I just checked and the Inkscape/bin folder is in the path. There's only the one control on the effect, so there isn't much I can be doing wrong. What can I do to troubleshoot this? Quote Link to comment Share on other sites More sharing options...
Pixey Posted December 11, 2020 Share Posted December 11, 2020 Are you just trying to remove the background? If so, you can do this for free here. If, on the other hand, you are trying to remove the 'bumpiness' of the canvas on the image, here is a solution I did for another person with the same problem. Athough not perfect, it is not easy to remove a texture without blurring.

Athough not perfect, it is not easy to remove a texture without blurring. Thanks for the suggestion. I've played around with that plugin, a little. As you found in the other thread, it's difficult to find something that hides the physical texturing without blurring and posterizing the skin tones so much that it plummets in quality. Was the original response I got correct? Is FFT the correct tool for this sort of situation? If someone can help me troubleshoot the issue I'm having, I'd like to give it a try. Should I look for another copy of libfftw3-3.dll and drop it into the Paint.NET folder? Quote Link to comment Share on other sites More sharing options...

I really don't know and hopefully @Reptillian who suggested it, can help you a bit more on what this does. I've downloaded this myself and also get a very black result. I'm also not sure where this libffw3-3.dll is supposed to go. I googled it and it sounds like it's supposed to be in the Windows Folder? Hopefully someone else can explain about this. There is another Plugin which may be of help: Quote How I made Jennifer & Halle in Paint.net My Gallery | My Deviant Art "Rescuing one animal may not change the world, but for that animal their world is changed forever!" anon.
