چکیده

1 An original technique, based on ridge point detection directly from gray scale ngerprint images, is proposed. Our method avoids serious problems that algorithms which perform binarization of ngerprint images have. Each step can be easily hardware implemented, allowing a relevant speed up of the whole pro-

Fingerprint Ridge Line Reconstruction

Reconstruction of fingerprint ridge lines is a critical pre-processing step in the identification of poor quality fingerprint images. This paper presents a new fingerprint ridge line reconstruction approach by way of ridge line tracing. In our research, the fingerprint ridge line in a gray scale image is viewed as a track of a ridge segment moving along the ridge. The curve tracing problem is s...

Fingerprint ridge allocation in direct gray-scale domain

Ridges and ravines are the main components constituting a "ngerprint. Traditional automatic "ngerprint identi"cation systems (AFIS) are based on minutiaematching techniques. The minutiae for "ngerprint identi"cation are de"ned by ridge termination and ridge bifurcation. Most AFIS perform ridge line following process to automatically detect minutiae based on binary or skeleton "ngerprint image. ...

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...

Combinatorial Classification of Pixels for Ridge Extraction in a Gray-Scale Fingerprint Image

Automatic Fingerprint Identification Systems (AFIS) are usually based on minutiae matching. Minutiae are the terminations and bifurcations of the ridge lines in a fingerprint image. Detection of ridge lines from a noisy gray-scale fingerprint image is a challenging task. In this work, a novel combinatorial approach is proposed for classifying each pixel into one of the three classes (crest, val...
