A Novel Fingerprint Matching Algorithm Based on Minutiae and
Global Statistical Features
Peng Shi, Jie Tian, Senior Member, IEEE, Qi Su, and Xin Yang
Abstract-The performance of Automated Fingerprint
Identification System (AFIS) is highly defined by the similarity
of effective features in fingerprints. Minutia is one of the most
widely used local features in fingerprint matching. In this paper,
we introduced two global statistical features of fingerprint
image, including the mean ridge width and the normalized
quality estimation of the whole image, and proposed a novel
fingerprint matching algorithm based on minutiae sets
combined with the global statistical features. The algorithm
proposed in this paper has the advantage of both local and
global features in fingerprint matching. It can improve the
accuracy of similarity measure without increasing of time and
memory consuming. Experimental results on FVC2004
databases showed that these improvements can make a better
matching performance on public domain databases.
I. INTRODUCTION
B ECAUSE of the stability and uniqueness, fingerprint is
widely used in biometric identification. The matching
method is one of the most crucial technologies in the
Automated Fingerprint Identification System (AFIS).
Whether two fingerprints are matched relies on the similarity
measure between the effective features of them. There are
mainly two kinds of features used in fingerprint matching:
local features and global features. Two most prominent local
ridge characteristics, called minutiae, are ridge ending and
ridge bifurcation [1]. Minutiae are the most widely used
features in the matching process. In the minutia-based
matching algorithms [2,3,4], the matching score calculations
