Direct gray-scale minutiae detection in fingerprints

Direct Gray-Scale Minutiae Detection in Fingerprints - Pattern Analysis and Machine Intelligence, IEEE Transactions on

Most automatic systems for fingerprint comparison are based on minutiae matching. Minutiae are essentially terminations and bifurcations of the ridge lines that constitute a fingerprint pattern. Automatic minutiae detection is an extremely critical process, especially in low-quality fingerprints where noise and contrast deficiency can originate pixel configurations similar to minutiae or hide r...

Towards Reconstructing Fingerprints From Minutiae Points

We show that minutiae information can reveal substantial details such as the orientation field and the class of the associated fingerprint that can potentially be used to reconstruct the original fingerprint image. The proposed technique utilizes minutiae triplet information to estimate the orientation map of the parent fingerprint. The estimated orientation map is observed to be remarkably con...

Fingerprints: Orientation Free Minutiae Extraction and Using Distances between Minutiae for Identification and Verification

Fingerprint recognition has become a standard in both access control and forensics. This is because fingerprints are unique to an individual. While there are many ways in which a fingerprint can be recognised one of the most common is to look at the endings and splitting of the ridges. These are called minutiae. This research undertakes to improve upon existing methods used in all parts of a mi...

Separating the real from the synthetic: minutiae histograms as fingerprints of fingerprints

In this study we show that by the current state-of-the-art synthetically generated fingerprints can easily be discriminated from real fingerprints. We propose a non-parametric distribution based method using second order extended minutiae histograms (MHs) which can distinguish between real and synthetic prints with very high accuracy. MHs provide a fixed-length feature vector for a fingerprint ...
