Fingerprint Core-point Detection Using Genetic Algorithms
Core-point is an essential feature in a fingerprint,and is also very important in fingerprint matching and fingerprint classification. This paper defines the fingerprint core-point and its orientation in a novel way,then a genetic algorithms(GAs)-based method is proposed to locate the position of the core-point and compute its orientation. First the orientation field information of fingerprint is used to determine the core-point candidate region,and the fitness function of core-point's position and orientation is devised according to the definition. Finally,GAs is used to search the position of the core-point along with its orientation in a fast way. The experimental results show that the proposed method can exactly locate the core-point and compute its orientation.
