Fingerprint Orientation Field Enhancement
This paper presents a new method to enhance the fingerprint orientation image. Orientation, as a global feature of fingerprint, is very important to image preprocessing methods used in automatic fingerprint identification systems (AFIS). The most popular, gradient-based method is very sensitive to noise (image quality). Proposed algorithm is an application of gradient-based method combined with...
متن کاملCombining Orientation Field for Fingerprint Matching
Minutia matching is a widely used method for fingerprint matching. In order to match regions containing no minutiae and match small-area fingerprints which contain not enough minutiae for matching, a method combining minutiae and orientation field is proposed for fingerprint matching. The proposed method leads to an improved performance compared with the minutiae-based method.
متن کاملFingerprint Classification Using Orientation Field Flow Curves
Manual fingerprint classification proceeds by carefully inspecting the geometric characteristics of major ridge curves in a fingerprint image. We propose an automatic approach of identifying the geometric characteristics of ridges based on curves generated by the orientation field called orientation field flow curves (OFFCs). The geometric characteristics of OFFCs are analyzed by studying the i...
متن کاملGradient Based Fingerprint Orientation Field Estimation
Accurate estimation of ridge orientation is a critical step in image preprocessing methods used in automatic fingerprint identification systems (AFIS). Fingerprint orientation plays important roles in fingerprint enhancement, classification and recognition. The most popular is gradient-based method. This paper reviews the algorithm parameters, determining the compromise between accuracy in high...
متن کاملFPGA Implementation of Orientation Field Estimation of Fingerprint Recognition Process
Most of the automatic fingerprint verification systems are based on minutiae pattern matching. The accuracy of the system depends on the quality and location of minutiae. Most of the time, the quality of the ridges in the fingerprint image is not well defined. This leads to failure of precise location of minutiae. Hence, it is essential to get distinct ridges from the fingerprint images. The or...
