In this paper, we study the long-term cooperative tracking in large areas using multiple unmanned aerial vehicles (UAVs). Firstly, a hybrid tracking algorithm, which switches between a correlation filters based tracker and a cascaded detector, is developed for the robust long-term tracking using a single UAV. Then, a centralized cooperation strategy is proposed to achieve cooperative tracking using...
Understanding the spatial distribution of human social-economic activities helps marketing, policy making, planning, and government management. With rapid growing of internet, communication technology and the high penetration of mobile phones, massive activity data is collected from people daily life, giving us an opportunity to estimate the national distribution of human activities. This paper proposed...
A Real-time and reliable detection of anomalies is an important and challenging task. Unlike most detection methods based on the statistical analysis of the packet headers (Such as IP addresses and ports), we propose a new nonlinear approach only using network traffic volumes to detect anomalies reliably. Our method is based on the largest Lyapunov exponent and the change-point detection theory to...
