Image Bandpass Filtering

Image Fourier filtering. Works creating a donut hard filter and convolving it in Fourier space. Handles also non square images.

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
