In Big Data era, telecom operators have massive data resources, such as user call data, user online data, user location data, network performance data, and so on. These data reaches PB level and is distributed in the NEs and interfaces. How to effectively carry out the collection, parsing, analysis for the amount of data to support the network construction, maintenance and optimization is a major...
With the rapid development of the Internet and speedy increase of the data size, there are more and more data intensive applications which often involve hundreds of megabytes of data. It is important and necessary to obtain the retrieval results from cross-media data quickly and accurately. Large scale cross-media data retrieval based on Hadoop is proposed to speed up the retrieval in this paper....
Gabor feature extracted by Gabor wavelet is widely used in face recognition and proved efficiency. But the dimension of the Gabor feature vector is so high that makes it very hardly to compute and store the feature directly in practice. Some methods are proposed to reduce the dimension of Gabor feature in literature. A new method to select the key points in face image is proposed in this paper, and...
This paper presents a decentralized method to the problem of multiple unmanned aerial vehicles (UAVs) cooperative search of an unknown area. Firstly, based on search map model, the multiple UAVs cooperative search problem is posed as a receding horizon (RH) optimization decision problem, and a RH based UAV search decision process is proposed. Then, this centralized online optimization problem is partitioned...
