Abstract
The core of fingerprint is a basis for fingerprint identification. widespread algorithms for core detection use the template matching technique. But these methods occasionally extract wrong cores which are not related with the real core of fingerprint.


This paper proposes a core detection method using normal direction information of the ridge. The proposed method extracts a core by calculating deviations of normal directions on the basis that the ridge radiates from its core in every direction. According to the experiment results, it is certain that the proposed method can extract a core more efficiently than the template matching method.
