Video-based fingerphoto recognition with anti-spoofing techniques with smartphone cameras
This work is concerned with the acquisition of fingerprints samples on smartphones with the built-in smartphone camera. A novel approach to capture multiple fingerphotos in a videostream with a smartphone camera and the processing of the photos for the finger recognition is discussed in this paper. The proposed technique ...
A topology based approach to categorization of fingerprint images
This paper discusses the use of betti numbers to characterize fingerprint and iris images. The goal is to automatically separate fingerprint images from nonfingerprint images; where non-fingerprint images of special interest are biometric samples which are not fingerprints. In this regard, an image is viewed as a ...
Social acceptance of biometric technologies in Germany: A survey
Since the past decade biometric technologies are field-proven, facilitating reliable and secure access control. Numerous successful deployments on large-scale systems, e.g. airports, confirm the feasibility of biometric recognition. However, applications of biometric systems involve privacy concerns, i.e. debates on ...
Decision robustness of voice activity segmentation in unconstrained mobile speaker recognition environments
The influence of fingerprint image degradations on the performance of biometric system and quality assessment
A preliminary study on the feasibility of storing fingerprint and iris image data in 2D-barcodes
Presentation attack detection using a generalizable statistical approach for periocular and iris systems
Predicting Dactyloscopic Examiner Fingerprint Image Quality Assessments
We work towards a system which can assist dactyloscopic examiners in assessing the quality and decision value of a fingerprint image and eventually a fingermark. However when quality assessment tasks of datyloscopic examiners are replaced by automatic quality assessment then we need to ensure that the automatic measurement ...
A fingerprint indexing scheme with robustness against sample translation and rotation
Automatic fingerprint identification systems (AFIS) are getting prevalent around the world, and the size of fingerprint databases involved in AFIS is continuously growing. Thus, studying fingerprint indexing algorithms is desirable in order to facilitate the search process in a large-scale database. In this paper, we ...
