CVB AEON FFT provides the best level of tools for rapid fourier transform.

The fastest calculation is provided with knowledge from various test for speed
Fourier transform can be applied to images other than 2n size (until now this has been a big barrier for fourier transform)

· Forward real to complex Fourier transform
· Backward complex to real Fourier transform
· Power spectrum and autocorrelation
· Cross spectrum and cross correlation
· Filtering in Fourier space
