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).

Thank you in advance
