Video shot boundary detection is an important step in many video applications. Since the rapid development of video editing technology, especially, the extensive use of sub-window in news video, the original method of video segmentation cannot efficiently detect the video shot boundary caused by special video technique. In this paper, previous temporal multi-resolution analysis (TMRA) work was extended by first using SVM (Supported Vector Machines) classify the video frames within a sliding window into normal frames, gradual transition frames and CUT frames, then clustering the classified frames into different shot categories. The experimental result on ground truth, which has about 21 hours (10,250 shots) news video clip, shows that the new framework has relatively good accuracy for the detection of shot boundaries. It basically resolves the difficulties of shot boundaries detection caused by sub-window technique in video. The framework also greatly improves accuracy of gradual transitions of shot.

Cell's immunological information is acquired through analyzing color immunofluorescence image. A pixel growing algorithm with dynamic seed values is proposed to extract fluorescent regions in the CIE (L*, a*, b*) uniform color space. Ellipse matching method is proposed to extract cells from the obtained fluorescent regions. Finally antigen information is acquired through computing and decomposing color of the cell with the pre-computation and discretization method. The methods proposed for the acquirement of cell's immmunological information are appropriately evaluated. The experiment indicates that acquired the immunological information meets practical medicine analysis.

Framework of the distributed β-PSML and its applications

beijing Gongye Daxue Xuebao / Journal of beijing University of technology 2005年第4期31卷 427-433页

作者： Su, Yi-La Liu, Chun-Nian Beijing Municipal Key Laboratory of Multimedia and Intelligent Software Technology College of Computer Science Beijing University of Technology Beijing 100022 China College of Information Engineering Inner Mongolia University of Technology Huhehaote 010062 China

For solving problems in a large-scale distributed Web environment, we propose the distributed β-PSML (problem solver markup language). The distributed β-PSML is an extension of the β-PSML that we have proposed before for complex adaptive, distributed problem solving, and can be easily used for automatic reasoning on the Web. By incorporating global information sources from the Semantic Web and social networks with locally operational knowledge-data bases in an enterprise portal together for decision-making and e-business intelligence, the reason of a distributed β-PSML can be implemented. The experimental results show that our considerations are valid by combining global and local information sources and our preliminary solution works well on the semantic Web.

In this paper, inspired by a unified probabilistic model of information retrieval, we propose a general framework of targeted marketing by considering three types of information, namely, the customer profiles, the product profiles, and the transaction databases. The notion of market value functions is introduced, which measure the potential value or profit of marketing a product to a customer. Four sub-models are examined for the estimation of a market value function. Based on market value functions, two targeted marketing strategies, namely, customer-oriented targeted marketing and product-oriented targeted marketing, are suggested. This paper focuses on the conceptual development of the framework. The detailed computation of a market value function and the evaluation of the proposed framework will be reported in another paper. © Springer-Verlag Berlin Heidelberg 2005.

Describing Service-Oriented Architecture by Extended Darwin

Wuhan University Journal of Natural Sciences 2005年第6期10卷 971-976页

作者： ZHANG Tao SHEN Mei-e YING Shi YE Peng LIANG Zao-qing State Key Laboratory of Software Engineering Wuhan University Wuhan 430072 Hubei China Computer Department Beijing Information Technology Institute Beijing 100101 China School of Computer Science Wuhan University of Science and Engineering Wuhan 430074 Hubei China

Describing Service-Oriented Architecture （SOA） is critical in the development of Web based system, in this paper, an approach for describing SOA by extended Darwin is proposed. The requirements for describing SOA, which are different from that of ordinary architecture, are highlighted firstly, and then a solution for extending Darwin is presented. Using the extended Darwin, service components and connectors can be described explicit by the extended construct, as well as precise operational semantics of SOA by the π-calculus. Finally an example of supply-chain management system is given for manifesting the effect of the extended Darwin.

It is crucial for highly security-critical information systems to accurately control the disaster recovery activities. Using optimization theory, we present a disaster recovery planning mathematical model. The model uses mathematical method to express diverse entities in information and disaster recovery system such as applications, facilities, resources, sub disaster recovery plans, budget, etc. It classifies various resources according to their utilization and payment, and identifies the significance of applications and the conflicts among sub disaster recovery plans. Through expressing relationships among applications, facilities, resources and sub plans, this model selects the best set of sub plans. This model has less subjective parameter and can evaluate disaster recovery planning objectively and quantitatively.

作者： Kun Wang Lihua Zhou Zhen Cai Zengxin Li Key Laboratory of Computer Network and Information Security of the Ministry of Education Xidian University Xi'an China National Info Security Engineering and Technology Research Center Beijing China

We present a Robust Disaster Recovery System Model (RDRSM) for highly security-critical systems to realize continuous service. Through strengthening safe communication ability, RDRSM guarantees secure and reliable command on disaster recovery. It uses selfsupervision function to monitor the integrality and security of system itself. Through GIS, this model makes disaster recovery system easier to use, manage and maintain. RDRSM possesses features of security, robustness and controllability and can be applied to environments such as e-government and bank. This model successfully conducted the construction of an important e-government disaster recovery system, which verified its feasibility and the significance of its components, such as disaster recovery planning, system supervision and robust communication support.

Proceedings of the International Conference on Active Media technology, AMT

作者： Junzhong Ji Jing Yan Chunnian Liu N. Zhong College of Computer Science and Technology Beijing University of Technology Beijing Municipal Key Laboratory of Multimedia and Intelligent Software Technology Beijing China Department of Information Engineering Maebashi Institute of Technology Maebashi-City Japan

In recent years, more and more people studied the Bayesian networks learning algorithm that integrates independence test with scoring metric. Based on the proposed hybrid algorithm I-B&B-MDL, a modified method is developed. There are two major contributions. Firstly, order-0 and partial order-1 independence tests are used to obtain an original graph of the network, which reduces the number of independence tests and database passes while effectively restricting the search space. Secondly, by means of the heuristic knowledge of mutual information, sort order for candidate parent nodes increases the cut-offs of the B&B search tree and accelerates search process. The experimental results show that the modified algorithm has high accuracy, and is more efficient in time complexity than other algorithms.
