Set the spots to exclude to zero.

Subject: FFT>Bandpass Filter: How to exclude particles or other foreground objects?

Hello everybody
I'm using the FFT>Bandpass Filter to suppress horizontal stripes (streaks)
in AFM images.
Is there a way to exclude particles or other foreground objects from the
fit? ...like selecting a threshold to include the background only and thus
restricting the stripes suppression only to a selection (i.e., to the
background).
