Delineation of oxide and sulfide zones in mineral deposits, especially in gold deposits, is one of the most essential steps in an exploration project that has been traditionally carried out using the drilling results. Since in most mineral exploration projects there is a limited drilling dataset, application of geophysical data can reduce the error in delineation of the sulfide and oxide zones....

Service-oriented architectures (SOA) and, in particular, Web Services designs are widely adopted for the development of interoperable systems. In a dynamic scenario, a composed service may exploit component services in order to complete its task; composed services are variously distributed, and offered by different providers in different security domains and under different load conditions. So,...

The ECG elimination is a vital tool for physiologist in detecting and classifying arrhythmia among human beings. One of the major challenges in ECG analysis is the delineation of ECG segments, that is P and T waves detection and delineation of an ECG waveform. Here we presents a new approach to address this problem, where delineation and detection can be done simultaneously. The proposed method...

BACKGROUND Consistent delineation of patient anatomy becomes increasingly important with the growing use of highly conformal and adaptive radiotherapy techniques. This study investigates the magnitude and 3D localization of interobserver variability of organs at risk (OARs) in the head and neck area with application of delineation guidelines, to establish measures to reduce current redundant va...

In this research, Interferometric Synthetic Aperture Radar (IFSAR) and Shuttle Radar Topography Mission (SRTM) data are used to delineate a portion of the Saint Louis Bay watershed (Mississippi). In addition to these two digital elevation databases, the National Elevation Data (NED) and the United States Geological Service’ Digital Elevation Model (USGS-DEM) are also used for delineation. Resul...

BACKGROUND AND PURPOSE Several acquisition strategies may be used for imaging supraaortic vessels by using contrast-enhanced MR angiography. The purpose of this study was to assess the effect of voxel size on image quality of MR angiograms. METHODS Fourty-four patients underwent 3D MR angiography in the coronal plane. Patients were randomly assigned into two groups according to the voxel size...

We propose a delineation algorithm that deals with bar-like structures of different thickness. Detection of linear structures is applicable to several fields ranging from medical images for segmentation of vessels to aerial images for delineation of roads or rivers. The proposed method is suited for any delineation problem and employs a set of BCOSFIRE filters selective for lines and line-endin...
