There appears to be a vertical and horizontal white line that passes through the center in the freq domain image. Is there a significance to this?

Great question. I have an answer, but what would you guess? Why would an image have a Fourier transform like this one?

I would guess that the lines relate to the rectangular-ness of the images. Since pixels are square, possibly there is a stronger signal exactly in the x and y dimensions, causing these lines.
