FingerprintFeatureExtraction
The important fingerprint minutiae features are the ridge endpoints (a.k.a. Terminations) and Ridge Bifurcations.
The feature set for the image consists of the location of Terminations and Bifurcations and their orientations
Installation and Running the tests
method 1
pip install fingerprint-feature-extractor
Usage:
import fingerprint_feature_extractor
img = cv2.imread('image_path', 0) # read the input image --> You can enhance the fingerprint image using the "fingerprint_enhancer" library
FeaturesTerminations, FeaturesBifurcations = fingerprint_feature_extractor.extract_minutiae_features(img, spuriousMinutiaeThresh=10, invertImage=False, showResult=True, saveResult=True)
method 2
- from the src folder, run the file "main.py"
- the input image is stored in the folder "enhanced". If the input image is not enhanced, the minutiae features will be very noisy
Libraries needed:
- opencv
- skimage
- numpy
- math
Note
use the code https://github.com/Utkarsh-Deshmukh/Fingerprint-Enhancement-Python to enhance the fingerprint image. This program takes in the enhanced fingerprint image and extracts the minutiae features.
Here are some of the outputs:
How to match the extracted minutiae?
Various papers are published to perform minutiae matching. Here are some good ones:
