SFinGe (Synthetic Fingerprint Generator)

SFinGe (Synthetic Fingerprint Generator) is a novel method for the generation of synthetic fingerprint images ("sfinge" is the Italian for "sphinx"). SFinGe can be used to create, at zero cost, large databases of fingerprints, thus allowing recognition algorithms to be simply tested and optimized.

Why a synthetic fingerprint generator?

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.
