FFT_RGB Photoshop plugin (re-written to open source)

[Ronald E. Chambers]

I've resurrected Photoshop plugin FFT_RGB and corrected the problems it has. I'd like a couple of people to test this new version Ft_iFt which is combined version of FFT and IFFT. It is used often to remove paper textures and other periodic noise from scanned images.

Handles:

• RGB files upto 30000 px on a side
• 8, 16, and 32 bits/channel
• x64 Windows only
• at present sums the channels in luminance mode but will allow individual channel processing
• side boundary condition handling.
• Photoshop cs6 - cc Might would in Elements as well.

Let me know if you will try it please.

Plugin will be released as open source after some testing.

FREE ;-);-) https://www.dropbox.com/s/revadeti5o67cb5/Ft_iFt02jan2018.zip?dl=0

I am trying it preliminary on an image with slanted lines, and it seems to be working well. Going to try it more.

It is really solid now. Let me know if you have any questions.

After some teething, I decided to separate the modules again. This mainly for use with scripting (dialog goes away). The innards are unchanged but you now will have an Ft.8bf and an iFt.8bf. See readme.txt file please. I'm not a programmer. Especially not for Windows so changes I've made are for the Fourier transform operation only.

I've also made available:

Another free script useful for viewing before and after shots or before and after processing. You can scroll one image across another of the same size.

This is a very nice plug-in. Nevertheless, I'd like to suggest the author to consider a version, witch could handle CMYK pictures as well (not only RGB). In per-channel mode this could proof beneficial for removing printing patterns, as the most printing processes are CMYK based.

Andreas,

Thanks for the interest and recommendation. I played with CMYK FT at one time on raw CMYK info and compared to RGB and what was suppressed in both were within a hair's width so decided to do only the RGB. CMYK is 33% more costly and buys nothing. Most files I found were RGB anyway. The way the algorithm works has little color separation but uses the spikes seen in KxKy space are suppressed.
