FFT package update
Posted: 2008-01-31T07:29:27-07:00
Hello everyone. I'm sorry it has been so long since I updated the proposed FFT package. I have been studying for LSATs (I know, I know). Below are links for updated fft routines for IM.

Fred has helped me develop a better demo - so here it is. You can build it from the trunk/ directory with <code>make demo</code>. The usage is pretty simple:
demo f my_file.png
(Performs a Fourier transform, outputs a tiff stack: R_magnitude, R_phase, G_mag, G_phase, B_mag, B_phase).
You can process the same stack after masking it, etc. with:
demo i my_file_F_Q16.tiff
Obviously, using the C functions is less restrictive, but this is an example of how to write code with the routines. As usual, post to the forum or email me directly with questions, comments.
