Abstract
A method for computer processing of an input image showing a fingerprint, the method including causing a spectral image constituting a Fourier transform of the input image to be displayed on a display screen; detecting user actions while the spectral image is displayed; modifying the spectral image based on the user actions into a modified spectral image; generating an output image constituting an inverse Fourier transform of the modified spectral image; and causing simultaneous display of the modified spectral image and the output image on the display screen.
