Abstract: In this paper, attempts are made to detect some basic shape of objects using ultrasonic sensor arrays with Artificial Neural Network (ANN). For this purpose two types of ultrasonic sensor ...

Electro-optical detectors are used to measure or sense the radiation emitted or reflected by objects within the detector’s optical field of view (FOV). Passive systems operate without any illumination ...

Abstract: For many object detection methods, occlusion is a challenge problem and researchers have been spending a lot of time on solving it. Recently, by using synthetic aperture imaging with a ...

As more unidentified objects were shot down by the U.S. Air Force in recent days, experts warned that there were an “endless” array of potential targets. By William J. Broad The United States is going ...

Scientists have spotted a “mysterious” object letting out giant blasts of energy, three times an hour. Whatever the object is – which is relatively nearby, at 4,000 lightyears away – it is nothing ...

Within many development languages, there is a popular paradigm of using N-Dimensional arrays. They allow you to write numerical code that would otherwise require many levels of nested loops in only a ...
