A fingerprint is the pattern of ridges and valleys on the surface of a fingertip. Each individual has unique fingerprints. Most fingerprint matching systems are based on four types of fingerprint representation schemes (Fig. 1): grayscale image (Bazen et al., 2000), phase image (Thebaud, 1999), skeleton image (Feng, 2006; Hara & Toyama, 2007), and
show that Gaussian noise added to low quality fingerprint images enables the extraction of useful features for biometric identification. The rest of the paper is organized as follows: Section 2 discusses fingerprint features and section 3 explains fingerprint recognition. Section 4 lists the techniques available for minutiae extraction in the
The high variability of fingerprint data (owing to, e.g., differences in quality, moisture conditions, and scanners) makes the task of minutiae extraction challenging, particularly when approached from a stance that relies on tunable algorithmic components, such as image enhancement. We pose minutiae extraction as a machine learning problem and propose a deep neural network - MENet, for ...
Minutiae feature extraction and matching are not only two crucial tasks for identifying fingerprints, but also play an eminent role as core components of automated fingerprint recognition (AFR) systems, which first focus primarily on the identification and description of the salient minutiae points that impart individuality to each fingerprint and differentiate one fingerprint from another ...
Fingerprints are the oldest and most widely used form of biometric identification. Everyone is known to have unique, immutable fingerprints. As most Automatic Fingerprint Recognition Systems are based on local ridge features known as minutiae, marking minutiae accurately and rejecting false ones is very important. However, fingerprint images get degraded and corrupted due to variations in skin ...
However, fingerprint images get degraded and corrupted due to variations in skin and impression conditions. Thus, image enhancement techniques are employed prior to minutiae extraction.
We pose minutiae extraction as a machine learning problem and propose a deep neural network – MENet, for Minutiae Extraction Network – to learn a data-driven representation of minutiae points. By using the existing capabilities of several minutiae extraction algorithms, we establish a vot-ing scheme to construct training data, and so train ...

fingerprint images, Thinning seen as a preprocess for minutiae extraction. The Proposed algorithm identifies the unrecoverable corrupted areas in the fingerprint and does not thin them; this is an important advantage of the proposed method because such corrupted areas are extremely harmful to the extraction of minutiae points.
Minutiae, as the essential features of fingerprints, play a significant role in fingerprint recognition systems. Most existing minutiae extraction methods are based on a series of hand-defined preprocesses such as binarization, thinning and enhancement. However, these preprocesses require strong prior knowledge and are always lossy operations. And that will lead to dropped or false extractions ...
In this paper, a fingerprint minutiae extraction method using CNNs is proposed. Particularly, a fingerprint-devoted light U-shaped network called F-Net is designed to classify pixels of the input into 37 categories, namely 36 classes corresponding to minutiae region pixels with the central minutia's orientation from 0 to 360° and 1 category ...

1. Introduction. Fingerprint is a widely used biometrics characterized as the ridge friction patterns on finger tips. After more than forty years of research, automatic fingerprint identification system (AFIS) has achieved a great success for wide applications , , .Traditional AFIS is usually based on contact fingerprints captured by pressing a finger on the scanner surface.
Fingerprint Extraction Minutiae Points. A good quality image is an essential for minutiae extraction. However, sometimes the image quality might poor due to various reasons and hence it becomes necessary to enhance the fingerprint image before minutiae matching of fingerprints. ... each ridge is characterized by numerous minute peculiarities ...
