The existing slender target detection methods based on optical satellite images are greatly affected by the perspective and solar perspective. Due to limited data sources, it is difficult implement a fully data-driven approach. This work introduces imaging parameters of images, which reduces influence perspectives perspectives, demand for amount data. We improve oriented bounding box (OBB) dete...

Pigment classification of paintings is considered an important task in the field cultural heritage. It helps to analyze object and know its historical value. This information also essential for curators conservators. Hyperspectral imaging technology has been used pigment characterization many years potential scientific analysis. Despite advantages, there are several challenges linked with hyper...

The purpose of this study was to quantitatively evaluate in a phantom model the practical impact of alteration of key imaging parameters on image quality and artifacts for the most commonly used fast T(2)-weighted MR sequences. These include fast spin-echo (FSE), single shot fast spin-echo (SSFSE), and spin-echo echo-planar imaging (EPI) pulse sequences. We developed a composite phantom with di...

Obtaining a lateral S-parameter image scan from positrons implanted into semiconductor devices can be a helpful research tool both for localizing device structures and in diagnozing defect patterns that could help interpret function. S-parameter images can be obtained by electromagnetically rastering a variable energy positron beam of small spot size across the sample. Here we describe a genera...

We present a modeling technique for the interaction of an elliptical-shape crack in a metal with an open-ended waveguide. The crack is first modeled by an appropriate number of short rectangular waveguides. The mode-matching technique is then used to calculate the scattering matrix of the new segmented waveguide structure. The probe reflection coefficient of the dominant mode is finally calcula...
