Fingerprint mosaicing entails the reconciliation of information presented by two or more impressions of a finger in order to generate composite information. It can be accomplished by blending these impressions into a single mosaic, or by integrating the feature sets (viz., minutiae information) pertaining to these impressions. In this work, we use Thin-plate Splines (TPS) to model the relative ...

A new approach is proposed in order t o construct a practical automatic identification system for seal impressions. The 3D (three dimensional) measurement method is investigated to select a suitable measurement system for seal registration. The seals are measured as 3D image by employing the range finder system. The pre-processing is performed to correct the slight slant on the measured seal su...

Two experiments were carried out to explore the effect of rendering and interface fidelity on subjective impressions of illumination and perceived presence after exposure to a virtual environment (VE). In particular, a study that compares a real-world task situation to its computer graphics simulation counterpart is presented. The computer graphics simulation was based on photometry data acquir...

People often form impressions of others in contexts where both relatively static demographic cues (e.g., age, race, gender) and situationally-flexible, dynamic emotion expressions) are available. We examined whether how attending to gender (male, female) versus expression (neutral, smiling) affects threat-based person impressions. In three experiments, we heightened the salience either categori...

While recent research examined the impressions projected by users of Social Network Sites through their relatively static online profiles, the addition of status updates to Facebook offers the opportunity to study a more fluid type of impression management. In this paper, we take a first look at data collected with a custom application designed to capture the impressions both “given” and “given...

The authors articulate a model specifying links between (a) individuals and the physical environments they occupy and (b) the environments and observers’ impressions of the occupants. Two studies examined the basic phenomena underlying this model: Interobserver consensus, observer accuracy, cue utilization, and cue validity. Observer ratings based purely on offices or bedrooms were compared wit...

This study investigated the effect of rinsing alginate impressions using acidic electrolyzed water on the dimensional change and deformation of stone models. Two brands of alginate impression materials were used. The impressions were rinsed using tap water or acidic electrolyzed water with a pH of 2.3, an oxidation-reduction potential of 1,230 mV, and a residual chlorine concentration of 45.0 p...

BACKGROUND Even though excellent impression materials are now available for making accurate replication for hard and soft tissue, the numerous dentists have faced lots of obstacles in making simultaneous impressions of multiple abutments. CASE DESCRIPTION This article describes a modified method of tray fabrication using auto-polymerizing acrylic resin and impression technique for multiple pr...

The validity of social perceptions was assessed on the basis of facial or vocal information. Specifically, impressions of stimulus persons' power and warmth were obtained on the basis of either a facial photograph or a voice recording. These were compared with the stimulus persons' self-reports along the same dimensions. Face- and voice-based impressions did predict self-view. The specific faci...

AIM Several new irreversible hydrocolloid formulations have recently become available with claims of an improved dimensional stability by the manufacturers. The aim of this study was to evaluate the accuracy of casts made from alginate impression materials poured immediately and after specific storage periods. METHODS AND MATERIALS Five alginates were tested: CA 37 (Cavex); Jeltrate (Dentsply...
