In many cases the average fingerprint ridge frequency in the whole fingerprint image should be determined. This parameter is, among other things, very important in procedures, where so-called fingerprint reference point has to be located. Unfortunately, as far, ridges frequency has been determined a priori, on the basis of anthropological measurements of the human population. This parameter is ...

The deployment of a fingerprint positioning method consists of an offline phase and a real-time phase. During the offline phase, a fingerprint database is built. This process is tedious and time consuming. Even so, the majority of WiFi-based indoor positioning methods implemented in practical indoor location–based service (ILBS) systems are the fingerprint method, because this method is accurat...

Fingerprint authentication is the most consistent and practicable methods of person appreciation. The only problem with functionality of Fingerprint authentication System is it depends on the eminence of image. The quality of fingerprint image affects by both surroundings and scanner’s-surface. The Fingerprint Trivia-Matching is not possible until the eminence of fingerprint image improve. The ...

Fingerprint identification is one of the oldest and popularly used forms of biometric identification system. Fingerprint image quality is of much importance to achieve high performance in Automatic Fingerprint Identification System (AFIS). Most of the fingerprint Recognition system relies on fingerprint ridges to extract the features. The fingerprint images which are corrupted due to variations...

Touch-less based fingerprint verification systems are free from the problems of image deformation, latent fingerprint issues and so forth that appear in the contemporary touch based fingerprint verification systems. Coupled with template protection mechanism, a touch-less fingerprint verification system is further enhanced. In this paper, a secure end-to-end touch-less fingerprint verification ...

A review of radio frequency microelectromechanical systems (RF MEMS) technology, from the perspective of its enabling technologies (e.g. fabrication, RF micromachined components and actuation mechanisms) is presented. A unique roadmap is given that shows how enabling technologies, RF MEMS components, RF MEMS circuits and RF microsystems packaging are linked together; leading towards enhanced in...

This paper presents complete behavioral analysis of a surface micro-machined MEMS varactor for frequency tuning application in voltage controlled oscillators in RF applications with high Quality factor and tunability. The dimensions of the MEMS device have been optimized with Finite Element Method based CoventorWare analysis and verified through lumped parameter analysis in Saber platform. The ...

Reference points play important role in the field of fingerprint recognition. It is mainly used for fingerprint classification and fingerprint matching. There are many methods proposed for fingerprint reference point detection like Poincare Index technique, Direction curvature technique etc. The purpose of this paper is to detect the reference points considering the uncertainty for imperfection...

Modelling MEMS involves a variety of software tools that deal with the analysis of complex geometrical structures and the assessment of various interactions among different energy domains and components. Moreover, the MEMS market is growing very fast, but surprisingly, there is a paucity of modelling and simulation methodology for precise performance verification of MEMS products in the nonline...
