How minutiae are used in fingerprint matching?
Minutiae based fingerprint matching is widely used for fingerprint verification. In this method first, Fingerprint image is enhanced using Fast Fourier Transform and converted to binary image for further processing. In second step, image is thinned and minutiae are extracted.
What is matching in fingerprint?
Fingerprint matching is the method of identifying a page type by using fingerprints. Specifically, a page's fingerprint is compared to the fingerprints in a database in which each database fingerprint has an associated page type.
How many minutiae does it take to make a match?
In America, there has never been a legal requirement for a minimum number of matching "points," though up until about 1943 (64 years ago), some law enforcment publications (such as the FBI's "The Science of Fingerprints") cited twelve points.
How do fingerprints identify minutiae?
Minutia points are detected by locating the end points and bifurcation points on the thinned ridge skeleton based on the number of neighboring pixels. The end points are selected if they have a single neighbor and the bifurcation points are selected if they have more than two neighbors.
