For linear dynamic systems in data processing, Kalman filter (KF) algorithm can produce more precise estimations of unknown variables and analyze complex state transition. For a complex application, the large scale of system states and the less runtime of KF algorithm are necessarily needed. Therefore, more available computing resources are crucial to accelerate computation. This paper presents an...
In 2014, TerraSAR-X (TSX) mission were extended by implementing two new modes. One is Staring Spotlight (ST) mode. The ST mode increases the high geometric resolution of the standard High Resolution Spotlight product. By widening the azimuth beam steering angle range and therewith extending the synthetic aperture an azimuth resolution of 0.24 m can be achieved. In this paper, some types of damage...
Digital elevation model (DEM) matching is a necessary task that must be conducted in many applications of remote sensing, especially for purposes of disaster surveillance (e.g., landslide, debris flow). In this paper, we propose a robust matching method based on contour lines and least squares surface matching. Challenges involve detecting stable and invariant control points (CPs) in un-deformed areas...
The grammar of facade structures is often related to regularly distributed signature patterns in high-resolution synthetic aperture radar (SAR) images. Given the structural details in the SAR image, algorithms for building extraction/monitoring should exploit this contextual information for an object-based analysis. In this paper we propose a framework to extract detailed high rise building features...
As the base infrastructure to support various cloud services, data center draws more and more attractions from both academia and industry. A stable, effective, and robust data center network (DCN) management system is urgently required from institutions and corporations. However, existing management schemes have several problems, including the difficulty to manage the entire network with heterogeneous...
Crowdsourcing is a new distributed computing paradigm that leverages the wisdom of crowd and the voluntary human effort to solve problems or collect data. In this paradigm of soliciting user contributions, the trustworthiness of contributions becomes a matter of crucial importance to the viability of crowdsourcing. Prior mechanisms either do not consider the trustworthiness of contributions or assess...
In mobile wireless networks, the emerging proximity-based applications have led to needs for highly effective and energy-efficient neighbor discovery protocols. However, existing works cannot realize the optimal worst-case latency in symmetric case, and their performances with asymmetric duty cycles can still be improved. In this work, we investigate asynchronous neighbor discovery through a code-based...
Cooperative communication is a new fashion to alleviate the low channel utilization and signal fading problems in today's wireless network. The success of cooperative communication heavily depends on the efficient assignment of relay resource. Auction theory has been applied successfully to allocate limited resources in wireless network for decades. However, most of the existing auction mechanisms...
