Generates a donut filter and performs fourier filter. It works as a
bandpass filter. Thakes care of the filtering also for non-square images
Inputs
Frm : Input Frame should be a 2D matrix
R_in : lowpass edge threshold from 0 to 1 in frequency % es 0.02
R_ou : longpass edge threshold from 0 to 1 in frequency % es 0.2
VIS : Visualiazation Boolean variable
Note that R_in < R_ou if you want to really filter something
Outputs
FrmFilt : Filtered frame
