I am facing the following problem: I have an image and a contrast sentivity function (CSF). The CSF is a function defined in the frequency domain and it is just a band-pass filter. The problem is that it is a 1D filter so I do not know how to apply it to the Fourier transform of the image.
I thought about creating a 2D filter based on the revolution around the zero frequency of the 1D filter but I do not know if it is mathematically correct or if it is the common procedure.
Thanks in advance!
