Spatial frequency

[Simon Rigoulot]

My name is Simon Rigoulot and I would want to compare groups of pictures
according to their spatial frequency.
More precisely, I would want, for different bands of spatial frequency, and
after a FFT or a wavelet transformation, to measure the energy of these
bands of spatial frequency and after that, compare these energies (with
ANOVA by example).

I Would want to know if it was possible with imageJ and if yes, the way to
obtain that.

Thanks for your attention

Simon Rigoulot
