A fingerprint classification algorithm is proposed in this paper. It is based on the features extracted from the directional field of the fingerprint image. To improve the accuracy of the directional field, an efficient estimation approach is developed. Based on the improved directional field, the singular points and the relative features are extracted to generate the input features of the fingerprint...
Minutiae pattern remains a widely used representation of a fingerprint. The research on minutiae matching never stops due to its complexity and intractability. In this paper, an efficient fingerprint minutiae matching algorithm is proposed. To obtain reliable reference minutiae pairs, the bank of coordinate systems is introduced. The coordinate systems bank is derived from the original minutiae features...
