Hello,
I tried contacting the author, but the email address is no longer
functional. I have not done my homework before asking the question...
The imtranslate function takes the absolute value of the image as it
is brought out of FFT-space. Is this because of some property of FFT
where it can potentially flip the sign of a pixel?
I am using this method to permute images that may have negative
values. Does anyone know why the absolute value is used here?
