In order to overcome the limitations of a single view of action recognition by using multi-view information, this paper proposes a novel method of multi-view human action recognition. The main steps involved in the process of recognition of action features are represented by fuzzy vector quantization; the membership vector is obtained after the action feature fuzzy. A fast and efficient Extreme Learning...
Real-time face recognition is one of the most challenging problems in face recognition. We propose a novel algorithm to address this problem based on a sparse representation based classification (SRC) framework. First, we remove the background through the background subtraction algorithm, extract the foreground, and then, extract the face, thereby reducing the workload of the latter algorithm to improve...
During recent years, Peer-to-Peer (P2P) Content Sharing Networks (CSNs) have intrigued researchers to measure and analyze them for the dominant proportion of P2P traffic volume and wide applications of the sharing platform. However, to the best of our knowledge, most of the measurement tools have not been updated under the current situations of P2P CSNs. In this paper, we develop an enhanced measurement...
In this paper we consider a novel design of space-time block code combined with pre-coding module transmission system. Theory of orthogonal designs has shown that such code cannot be simultaneously orthogonal, of rate 1, with full diversity order, for more than 2 transmit antennas. We propose in this paper a new way to overcome this limitation by adding a pre-coding module before transmitting space-time...
In order to optimize the kinematic and dynamic performance of a 2-DoF planar parallel mechanism used in hybrid machines, a multi-objective optimization method is introduced. Based on the compare of the common kinematic analysis method and dynamic analysis method, the kinematic and dynamic performances evaluation indices which can be used in the performance optimization are introduced. Then a multi...
Keyword search for smallest lowest common ancestors (SLCAs) is an important approach to identify interesting data nodes in XML documents. With the rapid growth of XML data in Internet, how to effectively process massive XML data becomes an interesting topic. As an open-source cloud computing platform developed in recent years, Hadoop is a trend to process large-scale data, which makes possible massive...
Stereo matching remains a difficult vision problem for the image noise, textureless regions, depth discontinuities and occlusions. This paper presents a novel adaptive window stereo matching algorithm based on seed voting to solve these ill-posed problems. There are three key contributions in this paper: combining color and gradient as conditional tags to restrain initial window size for further adaptively...
Conventional vascular interventional surgery (VIS) is performed under fluoroscopic X-ray guidance. Catheter operating systems have been developed to reduce physical stress and X-ray irradiation. However, the catheter operating systems are all attached to surgical bed or fixed at the tip of passive manipulator, which is inconvenient to position and adjust catheter operating system Furthermore, traditional...
This paper investigates the consensus problem of the multi-agent system. A new method is used to solve the problem, which is Laplace transform. According to the Laplace transform, the accurate solution of the system can be solved, and the state of the consensus center can be found. It is proved that the agents of the system will aggregate and form a cohesive cluster around the consensus center in...
In this paper, we consider a complex dynamical network with time-varying delays. We prove that the dynamical complex network is synchronized if the delays satisfy the linear matrix inequality. In addition, we analyze the synchronization of the given network based on the coupling configuration matrix and the delays of the synchronous target. Some simulations illustrate our theoretical results.
Low-rate denial-of-service attack is a novel category of attacks that are based on exploiting the adaptive behavior exhibited by several network and system protocols. This attack through periodically non-suspicious low-rate attack pulsing, to reduce the performance of the victims. Based on the simulation of low-rate denial-of-service on NS2 platform, we analyze the defense performance of queue management...
Recently, the broad applications of multi-agent systems in many areas have stimulated a great deal of interests in studying coordinated control problems. Previous flocking protocols do not consider the input saturation. In this paper, we investigate the flocking problem with a bounded control input. Under the assumption that the underlying network is connected, all agents can attain the same velocity...
Due to output similarity matrix often involves some error mappings when using multi-strategies for ontology alignment, how to extract the mappings from similarity matrix correctly and effectively will have an important influence on precision. In this paper, a novel approach is proposed, which employs Sufferage algorithm combined with logical reasoning to extract mappings. Firstly, distributed description...
Phase-change random access memory (PCRAM) is emerging as one of the most promising non-volatile memories for the next generation media due to its fast write/read speed, wide dynamic range, high degree of cycling endurance, excellent data retention, simple structure, low operating voltage, good compatibility with CMOS technologies, and easy applicability. The PCRAM utilizes a reversible phase change...
