A new approach to reference point location in fingerprint recognition

A New Reference Point for Fingerprint Recognition

A new reference point for fingerprint recognition called a focal point is proposed. The focal point is an expected focus of curved ridges of fingerprint images. The focal point is designed as a center of moment in polar coordinate for the fingerprint matching method. The focal point for any type of fingerprint images can be identified and tested with various orientation, elastic distortion and ...

A new fingerprint ridges frequency determination method

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 New Algorithm of Fingerprint Reference Point Location Based on Identification Masks

Department of Computer Science and Engineering

Indoor location estimation, the process of reckoning the location of a device in an indoor environment, remains a technical challenge due to the poor performance of GPS in such settings. While a substantial amount of work has been done in this context, particularly employing the Wi-Fi fingerprinting technique, the very approach has certain shortcomings. A major limitation is the need of time-an...

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...
