The paper introduces a video surveillance and event detection framework and application for semi-supervised surveillance use. The system development follows the guidelines of national strategy for surveillance systems. The aim is to generalize the interoperability, compatibility and legality in camera surveillance systems in Hungary. The system’s intended use is in automatic mode on camera feed...

A CZT Compton Camera (CCC) is being built using two three-dimensional (3-D) position-sensitive CZT detectors. Expected system performance was analyzed by analytical and Monte Carlo approaches. Based on the measurement of detector energy and position resolution, the expected angular resolution is &33 and &23 for a $303 FOV for 511 keV and 1 MeV c-rays, respectively. The intrinsic e$ciency for a ...

Event cameras are a new type of image sensors that output changes in light intensity (events) instead absolute values. They have very high temporal resolution and dynamic range. In this paper, we propose method to detect decode binary square markers using an event camera. We the edges by detecting line segments created from events current packet. The combined form marker candidates. bit value c...

This paper discusses a computer vision algorithm and a control law for obstacle avoidance for small unmanned air vehicles using a video camera as the primary sensor. Small UAVs are used for low altitude surveillance flights where unknown obstacles can be encountered. Small UAVs can be given the capability to navigate in uncertain environments if obstacles are identified. This paper presents an ...

This paper discusses a machine-learning (ML)based future received signal strength (RSS) prediction scheme using depth camera images for millimeter-wave (mmWave) networks. The scheme provides the future RSS prediction of any mmWave links within the camera’s view, including links where nodes are not transmitting frames. This enables network controllers to conduct network operations before line-of...
