SFinGe 4.0

SFinGe (Synthetic Fingerprint Generator) is a novel method for the generation of synthetic fingerprint images ("sfinge" is the Italian for "sphinx").
Testing a fingerprint recognition algorithm requires a large database of samples (thousands or tens of thousands), due to the small errors which have to be estimated, but collecting large databases of fingerprint images is:
- expensive both in terms of money and time;
- boring for both the people involved and for the volunteers, which are usually submitted to several acquisition sessions at different dates;
- delicate due to the privacy legislation which protects such personal data.
