use abs in comparison and returned image
When we look for maxima in Fourier space we need to use abs,
transform might have stron imaginary component and weak real one.
Inverse Fourier transform might have imaginary component since our filter
somewhat unphysical so we need to take abs of such image, and then
return it.
