However, fingerprint images are prone to degradation and corruption due to factors such as skin variations and impression conditions such as scars, dirt, humidity and non-uniform contact with the scanning device. Thus it is necessary to apply some type of image enhancement techniques before minutiae extraction.

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

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 ...

Fingerprint is a most well-known biometric based authentication system that gives a unique identity for each person. In this paper, an authentication framework to enhance the Fingerprint Minutiae Extraction and Matching (FMEM) technique is proposed. A Fully Connected Deep Convolutional Neural Network with Improved Scale-Invariant Feature Transform (FCDCNN-ISIFT) is proposed for feature ...

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

First, calculate the average distance D between two neighbour’s ridges.; Then calculate the distance between two minutiae points. Let’s call this distance d.; If d is less than D and the two minutiae points are in the same ridge then remove both of them.; After the removal of false minutiae points, mark the valid minutiae points and the image is matched on the basis of these minutiae points.

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 ...

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 ...
