Thanks Juan for the response!

Thanks again

`It appears that the problem was that numpy fft returns a complex array, which gave an error when trying to display it.`

By extracting only the real parts of the array, it seems to work fine. This is a sample of what I was trying to do:`import numpy`

from numpy import fft

from skimage import io, data

import matplotlib.pyplot as plot

im = data.coffee()

f = fft.fft2(im)

f2 = fft.ifft2(f)

r = numpy.real(f2)

plot.imshow(r)

plot.show()

Thanks again
