The study of identical twins can point out potential limitations in biometrics and forensic odontology. This case report presents three-dimensional (3D) palatal rugae analysis in monozygotic twins utilizing digital models obtained directly by scanning the maxillary dental arch with the iTero® intraoral digital scanner. The results show that the rugae patterns contain related but not identical f...

OCR (Optical Character Recognition) is the digital encoding of printed and handwritten characters from an image file created through a scanner or other optical imaging devices. In other words, OCR is a software program that converts image-texts into computerized or digital text (figure 1) . While OCR has been extensively used as the basic application of different learning methods in machine lea...

This Paper describes a hybrid system on 3D city modeling, data management and visualization component for 3D GIS infrastructure. The framework obtained high efficiency, without compromising the detail and accuracy of the result .The method utilize multi source data – digital camera and laser scanner to provide data redundancy required by automation. Classification and segmentation can be proces...

Comparing the today’s situation to the last ISPRS congress, where the very first commercial digital large format airborne sensors ADS40 (Leica Geosystems) line scanner and DMC (ZI-Imaging now Intergraph) frame based camera were launched into the market, an increase in number of new digital airborne sensors (some of them already introduced into operational use) is clearly obvious over the last 4...

This report describes a clinical technique for fabricating a maxillary implant-supported, removable complete dental prosthesis by using an intraoral digital scanner to register implant positions and soft tissue morphology. The presented technique uses computer-aided design/computer-aided manufacturing (CAD/CAM) technology with a subtractive manufacturing process to fabricate a milled bar (infra...

We propose in this paper a new method for measuring a number of leaf dimension parameters including height, width, average width, perimeter and area. A digital scanner is utilized to acquire leaf images, which unlike digital cameras, requires no calibration in terms of size and angle of the acquired images. Edge detection, filtering and thresholding algorithms are applied to identify the leaf s...

Non-intrusive component forensics involves identifying algorithms and parameters of a device based on its output data alone. This project extends several of these techniques from standalone digital cameras to cell phone cameras. Methods used include estimating a device’s color interpolation coefficients and noise feature parameters. Robustness to post-camera operations such as digital zoom and ...

The core principle of segmented detectors like AGATA [1], GRETA [2], that will be used in future for 4π gamma detection arrays, is the application of the concept of pulse shape analysis (PSA). The key ingredient for this analysis is a data base containing pulses for all the interaction points inside the segmented detector. A full 3D scanning of the detectors, which experimentally determines pul...

One of the frustrating things in the digital fabrication era is that its media are neither affordable nor easily accessible and usable. Three-dimensional (3D) fabrication media (DFM) such as 3D Printers and 3D Scanners have experienced an upsurge in popularity, while the latter remain expensive and hard to function. With this paper, we aim to present you the RhoScanner Project a an affordable a...

Recent developments in the field of digital image processing suggest to use line information for object reconstruction instead of or in addition to traditional methods based on distinct points. We have chosen a car as a real-world test object. Images were taken under natural illumination and scanned with a high precision scanner. Point measurement for image orientation was supported by image ma...
