Uses oriented gabor filter bank to enhance the fingerprint image. The orientation of the gabor filters is decided by the orientation of ridges in the input image.
pip install fingerprint_enhancer
Usage:
import fingerprint_enhancer # Load the library
import cv2
img = cv2.imread('image_path', 0) # read input image
out = fingerprint_enhancer.enhance_fingerprint(img) # enhance the fingerprint image
cv2.imshow('enhanced_image', out); # display the result
cv2.waitKey(0) # hold the display window
- Alternatively, the script "src/example.py" can be used to run the example for this library.
- go into the src folder
- if on "develop" branch, run the file "example.py"
- if on "master" branch, run the file file "main_enhancement.py"
-
The sample images are stored in the "images" folder
-
The enhanced image will be stored in the "enhanced" folder
run the command python devtool.py run to run linter checks.
The Develop Branch is what is up to date. Other branches might not be up to date.
- We use oriented gabor filters to enhance a fingerprint image. The orientation of the gabor filters are based on the orientation of the ridges. the shape of the gabor filter is based on the frequency and wavelength of the ridges.
