Touchless 2D Fingerprint Recognition

Most of the fingerprint recognition systems use touch-based acquisition devices, which suffer from important intrinsic problems, such as non-linear deformations of the captured images, non-uniform contrast of the fingerprint regions, presence of latent fingerprints on the sensor surface, sensibility to dust and dirt, and low social acceptance. Touchless fingerprint recognition systems based on CCD cameras are studied in order to overcome these problems.

With respect to techniques based on three-dimensional models, the studied methods based on a single touchless image have the advantage of requiring low-cost and small hardware setups, which can easily be integrated in mobile devices and consumer applications.

An important characteristic of the studied approaches is that they do not use finger placement guides, reducing the acquisition constraints with respect to most of the contactless fingerprint recognition systems in the literature.

The studied techniques regard different aspects of contactless biometric systems: acquisition, quality evaluation of biometric samples, computation of contact-equivalent images, matching algorithms, and computation of synthetic samples.
