We consider the very challenging task of restoring images (i) which have a large number of missing pixels, (ii) whose existing pixels are corrupted by noise and (iii) the ideal image to be restored contains both cartoon and texture elements.

The first processing step after fingerprint image acquisition is segmentation, i. e. dividing a fingerprint image into a foreground region which contains the relevant features for the comparison algorithm, and a background region.
