  1. 1. Symmetry Filters Applied to Fingerprints : Representation, Feature extraction and Registration

    Author : Kenneth Nilsson; Högskolan i Halmstad; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fingerprint recognition; symmetry filters; orientation field; multiscale filtering; singular points; orientation radiograms; registration; multiexpert; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : A common framework for feature extraction in fingerprints is proposed by use of certain symmetries. The proposal includes representation, filters, and filtering techniques for common features including minutiae points, singular points and the ridge and valley patterns. READ MORE

  2. 2. Evidence for "liveness" in face biometrics

    Author : Klaus Kollreider; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Motion estimation; Optical flow of lines; Quangles; Object detection; OFL; Liveness detection; Anti-spoofing measures; Structure tensor; Quantized angle features; Face biometrics;

    Abstract : Aliveness or "liveness" detection is a novel but crucial topic in biometrics. In this study we will investigate it for face biometrics. The problem is given by the real-time requirements of such a system to be able to avert advanced spoofing attempts, e.g. READ MORE
