In this paper we present a new robust approach for 3D face registration to an intrinsic coordinate system of the face. The intrinsic coordinate system is defined by the vertical symmetry plane through the nose, the tip of the nose and the slope of the bridge of the nose. In addition, we propose a 3D face classifier based on the fusion of many dependent(More)
In this paper we investigate the effect of image resolution on the error rates of a face verification system. We do not restrict ourselves to the face recognition algorithm only, but we also consider the face registration. In our face recognition system, the face registration is done by finding landmarks in a face image and subsequent alignment based on(More)
When, in a criminal case there are traces from a crime scene-e.g., finger marks or facial recordings from a surveillance camera-as well as a suspect, the judge has to accept either the hypothesis H p of the prosecution, stating that the trace originates from the subject, or the hypothesis of the defense H d , stating the opposite. The current practice is(More)
Automatic border control at airports using automated facial recognition for checking the passport is becoming more and more common. Aproblem is that it is not clear howreliable these automatic gates are. Ve ry fewindependent studies exist that assess the reliability of automated facial recognition for border control. In this evaluation study the reliability(More)
We propose a new dense local stereo matching framework for gray-level images based on an adap-tive local segmentation using a dynamic threshold. We define a new validity domain of the fronto-parallel assumption based on the local intensity variations in the 4-neighborhood of the matching pixel. The pre-processing step smoothes low textured areas and(More)
The Facial Identification Scientific Working Group (FISWG) publishes recommendations regarding one-to-one facial comparisons. At this moment a draft version of a facial image comparison feature list for morphological analysis has been published. This feature list is based on casework experience by forensic facial examiners. This paper investigates whether(More)
Blood pool agents (BPAs) for contrast-enhanced (CE) magnetic-resonance angiography (MRA) allow prolonged imaging times for higher contrast and resolution. Imaging is performed during the steady state when the contrast agent is distributed through the complete vascular system. However, simultaneous venous and arterial enhancement in this steady state hampers(More)
