Hello, I have 2 questions regarding the frequency filter in the
1) Is the filter an ideal filter (i.e. all frequencies outside of the
keep range are set to 0.0)?
2) How do I properly specify the range? For example, I have a 512x512
image. I want to pass the first 50% of the frequencies (low-pass
filter) and discard the upper 50% of the frequencies. Since the
highest frequency is 512/2=256 (i.e. Nyquist) I have a total frequency
range of 0->256. To pass only the lower 50% of frequencies do I
specify IntRange to be [0, 128]?
