What is A Fingerprint?
What is Fingerprint Recognition?
There are mainly two systems using fingerprints as a biometric:
Fingerprint identification system (FIS) and fingerprint verification system (FVS)

Fingerprint identification system (FIS) vs fingerprint verification system (FVS)

The algorithms that are used to recognize fingerprints are the pattern-matching method and minutia methods .

pattern-matching method :
Pattern-matching method verifies the identity of the patterns by directly comparing the objective fingerprint images with the registered image.[ 1]
Graphical center of fingerprint image (not necessarily defined by the fingerprint core) is cropped a fixed distance and compressed for subsequent match. The greater the difference between the stored template and the live comparison, the less likely the match. http://sales.fingertec.com/download/info/whitepaper-01.pdf minutia method:
Minutia method uses feature information of the terminal points and separate points of ridges of the fingerprint and their relative positions. [ 1 ] this algorithm is capable of improves the quality of the fingerprint ridge and
Extracts the characteristic points(end point ,Branching point) from it .

Comparison of previous fingerprint Recognition algorithms:[2]
Template Size vs. Search and Match Speed:
The size of a minutia template is directly related to the number of minutia extracted.
The size of the pattern-based template is directly related to the image
On average,
