Designing of Fingerprint Enhancement Based on Curved Region Based Ridge Frequency Estimation
Fingerprint enhancement algorithm is used to improve the clarity of ridges and valleys of input fingerprint images. These kind of algorithm make them more suitable for the minutiae extraction algorithm. The ultimate criterion for evaluating such an enhancement algorithm is the total amount of “quality” improvement when the algorithm is applied to the noisy input fingerprint images. There are va...
متن کاملFingerprint Image Enhancement using Wavelet over Gabor filters
Fingerprint identification is one of the most popular biometric technologies and is used in criminal investigations, commercial applications, and so on. The performance of a fingerprint image-matching algorithm depends heavily on the quality of the input fingerprint images. It is very important to acquire good quality images but in practice a significant percentage of acquired images is of poor...
متن کاملRidge Orientation Estimation and Verification Algorithm for Fingerprint Enhancement
Fingerprint image enhancement is a common and critical step in fingerprint recognition systems. To enhance the images, most of the existing enhancement algorithms use filtering techniques that can be categorized into isotropic and anisotropic according to the filter kernel. Isotropic filtering can properly preserve features on the input images but can hardly improve the quality of the images. O...
متن کاملA modified Gabor filter design method for fingerprint image enhancement
Fingerprint image enhancement is an essential preprocessing step in fingerprint recognition applications. In this paper, we propose a novel filter design method for fingerprint image enhancement, primarily inspired from the traditional Gabor filter (TGF). The previous fingerprint image enhancement methods based on TGF banks have some drawbacks in their image-dependent parameter selection strate...
متن کاملFingerprint Verification based on Gabor Filter Enhancement
Human fingerprints are reliable characteristics for personnel identification as it is unique and persistence. A fingerprint pattern consists of ridges, valleys and minutiae. In this paper we propose Fingerprint Verification based on Gabor Filter Enhancement (FVGFE) algorithm for minutiae feature extraction and post processing based on 9-pixel neighborhood. A global feature extraction and finger...
