Abstract
The invention discloses a feature recognition technology-based fingerprint recognition algorithm. The feature recognition technology-based fingerprint recognition algorithm comprises the following steps: 1) selecting a target area and dividing the target area into a, b and c subareas; 2) respectively selecting features d, e and f in the a, b and c subareas; 3) mapping the recognition features d, e and f with the subareas a, b and c one to one to form specific recognition features of the target area, and identifying the specific recognition features as g; 4) storing g in a database which is used for storing all the specific recognition features; and 5) carrying out screening recognition on the database by adopting a Fourier algorithm. According to the feature recognition technology-based fingerprint recognition algorithm, a brand new algorithm structural design is adopted, so that the accuracy and university of the fingerprint recognition algorithm are improved.
Description
Technical field
The present invention relates to algorithm field, specifically, specially refer to a kind of algorithm for recognizing fingerprint based on feature identification technique.
Background technology
Fingerprint, because it has unchangeable property, uniqueness and convenience, almost becomes the synonym of living things feature recognition. Fingerprint refers to the recessed uneven streakline producing of the positive surface skin epirelief of people's finger tips. The regular arrangement of streakline forms different line types. Starting point, terminal, binding site and the bifurcation of streakline, be called the details (minutiae) of fingerprint.
Summary of the invention
The object of the invention is to for deficiency of the prior art, provide a kind of algorithm for recognizing fingerprint based on feature identification technique, to address the above problem.
Technical problem solved by the invention can realize by the following technical solutions:
Based on an algorithm for recognizing fingerprint for feature identification technique, comprise the steps:
1) selected target region, is divided into a, b, c tri-sub regions by described target area;
2) difference selected characteristic d, e, f in described a, b, c tri-sub regions;
3) described recognition feature d, e, f and subregion a, b, c are shone upon one by one to the specific identification feature that forms target area, and be designated g;
4) deposit described sign g in database, described database is used for preserving all specific identification features;
5) adopt Fourier algorithm to screen identification to database.
Further, the target area in described step 1) is provided with 1 to 3.
Further, the database in described step 4) is based on windows platform.
Compared with prior art, beneficial effect of the present invention is as follows:
By adopting brand-new algorithm structure design, improve accuracy and the wide usage of algorithm for recognizing fingerprint.
