Modeling of Cavities Detection in The Tree Stemsection Using Radar Vector Network Analyzer (VNA) Elaborating Radon Transform

چکیده
Trees are one of the most useful plants for life on earth. However, trees can be harmful due to cavities in stem sections. Rapid detection is needed prevent several losses that may arise fallen trees. This research identified a hollow and non-hollow tree section flamboyant with sub-surface radar system. The sub surface system was modeled using Vector Network Analyzer (VNA) connected Vivaldi antenna. VNA emitted electromagnetic waves subsequently propagated penetrated section. propagation wave met boundary plane between wood cavity which reflected waves. caught by antenna display as S-Parameter. used working frequency 1 GHz – 10 300KHz - 8GHz. difference amplitude signal could seen from results measurements made at point. By implementing circular scanning method inverse radon transformation, this identify 19 cm diameter hole 6 9.5 filled water, respectively. It observed optimal obtained placing object antennas. has signified application detecting

15 صفحه اولLine Detection Using Radon Transform
To extract features from digital images, it is useful to be able to find simple shapes (straight lines, circles, ellipses, etc.). In order to achieve this goal, one can be able to detect a group of pixels that are on a straight line or a smooth curve. That is what a Hough transform is supposed to do. Since the Hough transform is a special case of Radon transform then line detection process is a...
متن کاملSkew Detection Using the Radon Transform*
In an automatic document conversion system, which builds digital documents from scanned articles, there is the need to perform various adjustments before the scanned image is fed to the OCR system. This is because the OCR system is prone to error when the text is not properly identified, aligned, de-noised, etc. Such an adjustment is the detection of page skew, an unintentional rotation of the ...
