A system to defecr and evaluafe rhe crack on the pavement ofrhe road was developed. A movie film is used as an input source. The system consists ofa speck! film scanner, high-speed image pmcmsor, and the workstation. This paper presents an ovewiew of the image processor and !he algorithms to detect cracks effmivefy on real-lime hardware.

We present a fast and accurate method to compose images delivered by a quadocular document scanner into a global consistent image. The Shift Detection by Restoration (SDR) approach is used to overcome document deformations. Our method outperforms state of the art panoramic image approaches and is able to work within one second on standard hardware.

Morphometry of brain structures based on magnetic resonance imaging (MRI) data has become an important tool in neurobiology. Recent multicenter studies in neurodegenerative diseases raised the issue of the precision of volumetric measures, and their dependence on the scanner properties and imaging protocol. A large dataset consisting of 1073 MRI examinations in 843 subjects, acquired on 90 scan...

PURPOSE The trueness and precision of acquired images of intraoral digital scanners could be influenced by restoration type, preparation outline form, scanning technology and the application of power. The aim of this study is to perform the comparative evaluation of the 3-dimensional reproducibility of intraoral scanners (IOSs). MATERIALS AND METHODS The phantom containing five prepared teeth...

We report a protocol using a common desk-top scanner and public domain software for measuring existing leaf area and leaf area removed as a result of herbivory. We compared the accuracy and precision of this method to that of a standard leaf area meter. Both methods were used to measure metal disks of a known area, the area of soybean (Glycine max L.) leaves, and the area removed by simulating ...

the maximum correlation value is chosen. The location giving maximum correlation value for the correct source estimates the exact scanning location. Two main issues in this extension of source camera identifi cation methods [3-5] are increase in computational complexity in estimating the correlation between reference pattern and test noise patterns of different sizes and overheads in estimating...
