Segmentation of Moving Object Using Background Subtraction Method in Complex Environments
(Společnost pro radioelektronické inženýrství, 2016-06)Background subtraction is an extensively used approach to localize the moving object in a video sequence. However, detecting an object under the spatiotemporal behavior of background such as rippling of water, moving curtain ... -
Triangle/Square Waveform Generator Using Area Efficient Hysteresis Comparator
(Společnost pro radioelektronické inženýrství, 2016-06)A function generator generating both square and triangle waveforms is proposed. The generator employs only one low area comparator with accurate hysteresis set by a bias current and a resistor. Oscillation frequency and ... -
Ultra-Broad Band Radar Cross Section Reduction of Waveguide Slot Antenna with Metamaterials
(Společnost pro radioelektronické inženýrství, 2016-06)To reduce the radar cross section of a waveguide slot antenna, a three-layer metamaterial is presented based on orthogonal double split-ring resonators. The absorption characteristics of three-layer metamaterial are ...
