Now that we have several ways to apply a spatial space kernel to an image:
imfilter(img, kern)
ifft(fft(img) .* fft(kern))
For the convolution theorem, we have utils like fftshift/ifftshift. We also have freqkern and spacekern functions.
fftshift
ifftshift
freqkern
spacekern
Although these are "obvious" for people who already know them and use them in daily life, we need one or two demos to explain them.
