I have created an initial tutorial for using Fourier Transforms with ImageMagick. It can be found on my web site at http://www.fmwconcepts.com/imagemagick/ ... urier.html.
Note that it does contain a bit of mathematics as an introduction. So for those not interested, just skip down to the section FFT/IFT In ImageMagick.
I am working with Anthony, now, to rewrite my tutorial and format it for use in his ImageMagick Examples pages.
The tutorial is not complete as I am adding some additional advanced applications that will require some new scripts to demonstrate. But the basic features that anyone can use now are currently described.
