Abstract (Summary of the Work)

A new method for preprocessing fingerprint images is proposed here. It uses a new Enhancement technique , which is suitable for any Image that contains oriented patterns. Enhancement step is followed by Ridge Crispening. The resultant Image contains a number of ridge breaks. In the next step spurious breaks are removed. The decisive conditions for removing these breaks are based on (1) Eight neighborhood information as well as on (2) directionality at the candidate point. Ridges are then Smoothed and Binarized in subsequent steps. Finally the two tone Thinning is performed to get the perfect demarcated Ridges and valleys. The method proposed is compared with some standard methods.
