Hi Alessandro, hann() is in the signal package which is a dependency of the image package. You should have signal installed unless you installed image with the -nodeps flag (or you're using a very old version of the signal package). However, hann() is nothing more than a wrapper for hanning() which is in core so I commit this change.
