This paper proposes a three-dimensional (3D) body scanning system that uses passive stereo vision with a robot arm. So far, the reported 3D body scanning systems employ active 3D measurement methods. However, active methods use structured illumination or laser scanning, which is not desirable in many systems applied to human. A major problem of using passive stereo vision for 3D measurement is its...
This paper presents an efficient algorithm for iris recognition using phase-based image matching - an image matching technique using phase components in 2D discrete Fourier transforms (DFTs) of given images. Experimental evaluation using the CASIA iris image databases (versions 1.0 and 2.0) and Iris challenge evaluation (ICE) 2005 database clearly demonstrates that the use of phase components of iris...
Dental records are often used to identify victims of massive disasters, where the conventional biometric features, e.g., face, fingerprint, iris, etc., are not available. Human identification using dental records is to match an unidentified individual's postmortem radiographs against a set of identified antemortem radiographs. This paper presents an efficient dental radiograph registration algorithm...
A palm, a large inner surface of a hand, contains pattern of ridges and valleys much like a fingerprint. The palmprint is expected to be more distinctive than the fingerprint, since the area of the palm is much larger than that of the finger and the palm has additional distinctive features such as principle lines, ridges, minutiae points, singular points and texture. This paper presents a palmprint...
