How to Generate Synthetic Fingerprints with SFinGe Full Version
SFinGe (Synthetic Fingerprint Generator) is a novel method for the generation of synthetic fingerprint images. It can be used to create large databases of fingerprints for testing and optimizing fingerprint recognition algorithms. SFinGe can produce very realistic fingerprints that capture the main variations of fingerprints in nature.

In this article, we will explain how to obtain and use SFinGe full version, which offers more features and options than the demo version. We will also show some examples of synthetic fingerprints generated by SFinGe.
How to Obtain SFinGe Full Version
SFinGe full version is available for academic and research purposes only. To obtain it, you need to fill out a request form on the website of the Biometric System Laboratory at the University of Bologna[^1^]. You will receive an email with a link to download the software and a license key.
SFinGe full version is compatible with Windows XP, Vista, 7, 8 and 10. It requires at least 512 MB of RAM and 100 MB of disk space. It supports multiple languages, such as English, Italian, Spanish, French and German.
How to Use SFinGe Full Version
SFinGe full version has a graphical user interface that allows you to customize various parameters and options for generating synthetic fingerprints. You can also use a command-line interface for batch generation.
The main steps for generating synthetic fingerprints with SFinGe full version are:
Select the fingerprint shape (rectangular or elliptical) and size (in pixels).
Specify the number and location of the fingerprint cores and deltas (singular points).
Adjust the orientation correction, which allows to generate more realistic directional images.
Choose the ridge density map, which determines the thickness of the ridges.
Select the ridge pattern generation algorithm (Gabor-like filters or Fourier transform).
Apply some morphology operations (erosion or dilation) to simulate different dryness or pressure levels.
Add some noise and distortion effects to simulate skin plasticity and sensor imperfections.
Render the fingerprint image with contrast adjustment, rotation and translation.
You can also generate different impressions of the same finger by using the same parameters but changing the random seed.
Examples of Synthetic Fingerprints Generated by SFinGe Full Version
Here are some examples of synthetic fingerprints generated by SFinGe full version with different parameters and options:
As you can see, SFinGe full version can generate very realistic and diverse synthetic fingerprints that can be used for various applications in biometrics research. 29c81ba772
