Object tracking, especially human tracking is one of the challenging research problems in computer vision. Although the performance has gained some positive changes recently, there is still room for improvement. In this paper, we introduce an approach for human detection and tracking using Convolution Neural Network (CNN) and Hungarian Algorithm (HA). A CNN is used to localize multiple human beings...
Spectrum Sensing (SS) techniques play an important role in the Cognitive Radio (CR) systems. In recent years, many spectrum sensing techniques have been proposed in the literature to identify the state of the Primary Users (PUs) in the temporal domain. However, these techniques are usually interested in the current state of channel without consideration to their status in the past. In this paper,...
A novel compact microstrip dual-band bandpass filter (BPF) using square ring resonators and good selectivity is proposed in this letter. The characteristics of the dual-mode resonator are investigated by using even-odd mode analysis. It is found that, the even- and odd-mode of resonators can be regulated by adjusting the lengths of open folder and square ring. Meanwhile, four transmission zeros are...
This letter presents a novel compact microstrip wideband bandpass filter (BPF) based on square ring short-stub loaded resonator (SRSLR). The SRSLR is able to generate three resonances over the wide frequency band, while the fourth resonance is far away. In this design, by tuning the lengths of square ring and short-stub, the filter has an adjustable fractional bandwidth from 29.8 to 71.9%. Moreover,...
