Contactless fingerprint reader. The contactless fingerprint reader has one or more light sources adapted to emit light under different lighting conditions, a first camera adapted to successively capture first images of a subject captured with and without flash light, at least one second camera adapted to capture second images from different angles, one or more sensors adapted to generate one or more spatial-temporal signals representing a change of a distance between said subject and one or more locations of the contactless fingerprint reader, and communication module for sending the first images, said second images, and the one or more spatial-temporal signals to an anti-spoofing device.

Anti-spoofing for contactless fingerprint readers

The present invention relates to a method to segment slap images and to generate accurately labelled individual fingerprints, said method comprising the following steps:

Slap segmentation of contactless fingerprint images

The present invention relates to a method to generate a slap/fingers foreground mask to be used for subsequent image processing of fingerprints on an image acquired using a contactless fingerprint reader having at least a flash light, said method comprising the following steps:
