This paper propose a vector quantization (VQ) technique to solve the problem of handwritten signature verijication. A neural ‘gas’ model is trained to establish a reference set for each registered person with handwritten signature samples. Then a test sample is compared with all the prototypes in the reference set and the system outputs the label of the writer of the word. Several difSerent fea...

Interactive montage combines the elements of play and visual representation. The analysis of four examples of interactive montage in reference to a first person point of view highlights the importance of control and spatial reference between player-character and virtual environment. Both emerge as conditions for meaningful interactive montage. The resulting visualization style adjusts to the ne...

This paper disctu;ses some advances in non-contact, interferometric optical profilers. Topics discussed include: (i) The advantages of using a white light source, rather than a laser source, (ii) The tradeoff between the use of Michelson, Mirau, and Linnik interferometers for different fields of view and different lateral resolutions, and.(iii) Techniques for removing errors in the reference su...

OBJECTIVES To evaluate whether low glycosylated hemoglobin (HbA1c), blood pressure (BP), and total cholesterol (TC) are associated with lower risk of all-cause mortality in very old individuals with type 2 diabetes mellitus. DESIGN Population-based cohort study. SETTING Primary care database in the United Kingdom. PARTICIPANTS Individuals aged 80 and older with type 2 diabetes mellitus (N...

How are articles about art historical actors interlinked within Wikipedia? Lead by this question, we seek an overview on the link structure of a domain specific subset of Wikipedia articles. We use an established domain-specific person name authority, the Getty Union List of Artist Names (ULAN), in order to externally identify relevant actors. Besides containing consistent biographical person d...

In this paper, a novel algorithm for facial recognition is proposed. The technique combines the color texture and geometrical configuration provided by face images. Landmarks and pixel intensities are used by Principal Component Analysis and Fisher Linear Discriminant Analysis to associate a one dimensional projection to each person belonging to a reference data set. Each of these projections d...

A novel dynamic link architecture based on multiscale morphological dilation-erosion is proposed for face verification in a cooperative scenario where the candidates claim an identity that is to be checked. More specifically, a sparse grid is placed over the facial region of the image of each person in the reference set. Multiscale morphological operations are employed then to yield a feature v...

Recent advances in experimental science have made it possible to investigate the perceptual processes involved in generating a sense of owning an entire body. This is achieved by full-body ownership illusions which make use of specific patterns of visual and somatic stimuli integration. Here we investigate the fundamental question of the reference frames used in the process of attributing an en...

Behavioural biometric is related to what a person does, or how the person uses the body. Keystroke dynamics (or typing rhythms) is an innovative behavioural biometric technique, refers to a user’s habitual typing characteristics. These typing characteristics are believed to be unique among large populations. Keystroke dynamics allows for the design of more robust authentication systems than tra...

This paper propose a method of writer verification based on on-line features extracted from a process of drawing a figure, and evaluate its performance on handdrawn figures by genuine writers and pretenders. In the proposed method, a person in registration writes only the reference figure, which is composed of as many parts as possible and the person can be verified with a arbitrary part of the...
