Steps In Fingerprint Enhancement Techniques

چکیده
In this paper we study that fingerprints are the oldest and most widely used form of biometric identification. The widespread use of fingerprints, there is little statistical theory on uniqueness of fingerprint minutiae. A critical step in study statistics of fingerprint minutiae is to reliably extract minutiae from the fingerprint images. Automatic and reliable extraction of minutiae from the fingerprint images is crucial step in fingerprint matching However, fingerprint images are rarely of the perfect quality. They are degraded and corrupted due to variations in skin and the impression conditions. The quality of input fingerprint images plays important role in the performance of automatic identification and the verification algorithms .Thus, image enhancement techniques are employed prior to minutiae extraction to obtain a more reliable estimation of minutiae locations.

A Robust Strucutural Fingerprint Restoration
Fast and accurate ridge detection in fingerprints is essential to each AFIS (Automatic Fingerprint Identification System). Smudged furrows and cut ridges in the image of a finger print are major problems in any AFIS. This paper investigates a new online ridge detection method that reduces the complexity and costs associated with the fingerprint identification procedure. The noise in fingerprint...

متن کاملAutomatic Fingerprint Recognition Scheme and Enhancement
In this paper we demonstrate the techniques for improved fingerprint recognition. We mainly focused on the study of decomposition of image, feature extraction and feature match. A fingerprint is the reproduction of fingertip impressions and produced when a finger is pressed against a smooth surface. The most evident structural characteristic of a fingerprint is its pattern of interleaved ridges...
متن کاملFingerprint Segmentation
In this thesis, a new algorithm has been proposed to segment the foreground of the fingerprint from the image under consideration. The algorithm uses three features, mean, variance and coherence. Based on these features, a rule system is built to help the algorithm to efficiently segment the image. In addition, the proposed algorithm combine split and merge with modified Otsu. Both enhancements...
