Detection of Fingerprint Alteration Using Scars, Minutiae Density and Ridge Discontinuity
نویسنده
چکیده
A novel method for detecting altered fingerprints using scars, minutiae density and ridge discontinuity is proposed here.This paper mainly focuses on FFT enhancement for ridge discontinuity analysis and use of scars along with ridge discontinuity and minutiae density for alteration detection. The scar is detected by adaptive average filtering and thresholding. This method is found suitable for the detection of all types of alteration viz. obliteration, distortion and imitation.

Singular Points and Minutiae Detection in Fingerprint Images Using Principal Gabor Basis Functions
In the past, most researchers concentrated on the continuity of ridge structures. Because the principal Gabor basis functions (PGBFs) only have large response values with similar orientation and spatial-frequency, a local fingerprint image is represented by a PGBF. We, on the contrast, focus our attention on the discontinuity of ridge structures. This is because the important features (includin...

Background: In forensic sciences, the nature and variability of configurations of epidermal ridge minutiae has practically been explored in the evaluation and comparison of fingerprints, including partial fingerprints. The objectives of the present study were to determine the potential of fingerprint minutiae (level two features) in estimation of sex using likelihood ratio and posterior probabi...

In the modern era, with the growing need of biometric technologies, spoof attacks are becoming a serious concern. A number of solutions have been proposed to detect the use of fake fingerprints[3]. This paper takes advantage of skin elements in fingerprints, namely: minutiae points and Ridge Bifurcations to investigate spoof attacks. Graphical results using histogram approach in MATLAB show the...
متن کاملNew Ridge Flux Analysis for Fingerprint Minutiae Detection
This paper presents a new fingerprint minutiae extraction approach that is based on the analysis of the ridge flux distribution. The considerable processing time taken by the conventional approaches, most of which use the ridge thinning process with a rather large calculation time, is a problem that has recently attracted increased attention. We observe that the features of a ridge curve are ve...
متن کاملA chaincode based scheme for fingerprint feature extraction
A feature extraction method using the chaincode representation of fingerprint ridge contours is presented. The representation allows efficient image quality enhancement and detection of fine minutiae feature points. The direction field is estimated from a set of selected chaincodes. The original gray-scale image is enhanced using a dynamic filtering scheme that takes advantage of the estimated ...
