The advent of Digital Fingerprint processing system motivates to review new concepts of fingerprint matching algorithm. One of the important, fingerprint matching is minutiae-based. Minutiae-based techniques are work on substructure pair. These substructure pairs are basically, ridge ending and bifurcation points. All the biometric techniques have received the most attention for person Therefore, the recognition of minutiae features became the most common basis for automated fingerprint verification. The most widely used minutiae features used for automated fingerprint verification were the ridge ending and the ridge bifurcation.

Fingerprint bifurcation

Fingerprints are identified by both macro and micro features. A)A class of fingerprints characterized by ridge lines that enter the print from one side and flow out the other side B)An inkless device that captures digital images of fingerprints and palm prints and electronically transmits them to an AFIS C)A square electronic dot that is used to compose a digital image D)A fingerprint impressed in a soft surface E)A class of fingerprints characterized by used in fingerprint examination. 1.1.2 This document compliments the Forensic Science Regulators‟ Fingerprint Comparison appendix FSR-C-128 to his Codes. 1.1.3 The document avoids where possible terminology used in international standards and legal definitions (other than to translate meaning applicable to fingerprint examination).

(a) Ridge ending (b) Bifurcation Figure 1.1: Example of a ridge ending and a bifurcation. Fingerprint images are rarely of perfect quality. They may be degraded and corrupted with elements of noise due to many factors including variations in skin and impression conditions. This degradation can result in a signiﬁcant number

*Ridge Ending. *Break. BIFURCATION: A ridge characteristic, which occurs when a friction ridge splits into two and the friction ridges on either side diverge to make room for it.

A fingerprint is a reproduction of the ridge formation of a finger on a surface. the point of bifurcation is the point of delta, also known as the Outer Terminus. In automatic fingerprint recognition system only ridges bifurcation and ridge ending are commonly used. Automatic finger print matching involves determining the endings, ridge bifurcation, fingerprint recognition.

These substructure pairs are basically, ridge ending and bifurcation points. Fingerprints are the most common authentic biometrics for personal identification, especially for forensic security.

Fingerprint feature detection is one of the key techniques of automatic fingerprint identification. There are some problems of rotation and shift in the present fingerprint feature detection. This paper has given an algorithm of bifurcation detection based on neural network template matching. Correlative matching is to calculate the correlative value between template and target image according Fingerprint-Recognition-System. Matching minutiae (ridge & bifurcation) points using affine invariant transform features. Steps: Extracting ridge and bifurcation points using Otsu tresholding and morphological operations.

second bifurcation to form a single ridge again. A human fingerprint may contain 75-175 ridge path deviations. Common. Level 2 details are shown in. Figure 4.

These consist of ridges and valleys. In a fingerprint, ridges are represented by the dark lines whereas the valleys are represented by the white area between the ridges. The minutiae points in the fingerprint consist of ridge ending as well as bifurcation.
