BANDPASS FILTERING IN FREQUENCY DOMAIN

The application presents low and a high frequencies in an image. Filtering is achieved in the Fourier domain,
where the coefficients representing high or low frequencies are cut off and then an inverse FFT is computed.
.
Three images will be displayed in the window : the original image, the image after low pass filtering,
and the image after high pass filtering.

An application window should appear on your screen.
