Up-to-date information on urban air pollution is of great importance for health protection
agencies to assess air quality and provide advice to the general public in a timely manner. In …

Touchless fingerprint recognition systems do not require contact of the finger with any
acquisition surface and thus provide an increased level of hygiene, usability, and user …

Billions of contact-based fingerprint images have been acquired in large databases.
Contactless 2D fingerprint identification systems have emerged to provide more hygienic …

To solve the problems associated with conventional 2-D fingerprint scanners such as skin
deformation and print smearing, in this paper we introduce a noncontact fingerprint scanner …

Biometric systems consist of devices, algorithms, and procedures used to recognize
individuals or classes of individuals based on their physical or behavioral characteristics …

Traditional fingerprint recognition systems require that the users touch a sensor to perform
biometric acquisitions. In order to increase the usability, acceptability, and accuracy of …

Optical coherence tomography provides a 3D representation of fingertip skin where surface
and internal fingerprints are found. These fingerprints are topographically identical …

“The friction ridge pattern is a 3D structure which, in its natural state, is not deformed by
contact with a surface”. Building upon this rather trivial observation, the present work …

Protecting pharmaceutical products against counterfeiting or the fraudulent importation of
donated and discounted drugs will remain a permanent challenge in light of the increased …
