It was recommended in an earlier post that to "deskew" a black and
white scanned image I should use a 1D Fast Fourier Transform on the
rows and columns of the scanned image. Although I have a large
mathematical background, I am not too familiar with FFTs. If I were to
input an image into some function that does this, what would it return
and how would I interpret it? Has anyone done this before?
