Fourier Transform and Fourier Transform Surface

[sosshewale]

Hello,

I am new to image-processing and very much puzzled with the terms like "Fourier Transform" or "Fourier Transform Surface" of image.
I guess they are 2D and 3D images.


I am interested to create images similar to the images created by tool called FTL-SE (jCrystal - http://www.jcrystal.com/products/ftlse/index.htm). The jCrystal lacks scripting support (very limited support). That works on Windows environment but does not work on Linux.
On Linux - i tried using that under wine - but fails to save images in .bmp.

But limited support to programming interface is bottleneck.

Thanks in advance,

ImageMagick can do FFT processing similar to what this tool does. You can run it from the command line, but I am not aware of whether it has been included in any IM API. One of the IM experts may have to reply on that point.
