A novel active contour model for image segmentation using local and global region-based information

Ling Zhang, Xinguang Peng, Gang Li, Haifang Li

Machine Vision and Applications > 2017 > 28 > 1-2 > 75-89

In this paper, we propose a novel level set geodesic model for image segmentation. In our model, we define a hybrid signed pressure force (SPF) function integrating local and global region-based information to segment inhomogeneous images. The local region-based SPF utilizes mean values on local circular regions centered in each pixel. By introducing the local image information, the images with intensity...

The Research and Implementation of Heterogeneous Data Integration under Ontology Mapping Mechanism

Jing Bian, Hai Zhang, Xinguang Peng

Lecture Notes in Computer Science > Web Information Systems and Mining > Semantic Web and Ontologies > 87-94

To deal with semantic heterogeneity among heterogeneous data sources, ontology is imported to the traditional data-integrated middleware. Domain ontology and local ontology are constructed as overall data view and local data view respectively. By establishing the mapping between domain ontology and local ontology, the problem of semantic heterogeneity is settled and semantic standard is reached. In...

Web Application Security Based on Trusted Network Connection

Yongwei Fu, Xinguang Peng

Lecture Notes in Computer Science > Web Information Systems and Mining > Web Services and E-Learning > 420-427

This paper introduces the security of Trusted Network Connection into Web applications. To solve the security of Web applications and the application limitations of Trusted Network Connection, which is only widely used in LAN and VPN, a new method used for Web application security is presented in the paper based on the thought of Trusted Network Connection. Through the model design and the system...

Unbalanced tree‐formed verification data for trusted platforms

Donglai Fu, Xinguang Peng, Yuli Yang

Security and Communication Networks > 9 > 7 > 622 - 633

Validation is an alternative approach to the establishment of the trust between two or more entities. The validation allows a challenger to evaluate the trustworthiness of an attesting system based on provided evidence. Early attempts show the evidence is always organized in a linear structure or a balanced tree. These methods, however, are not optimal when facing a complex system and privacy issues...

A Context-Aware Model Based on Mobile Agent

Ying Wang, Xinguang Peng

Communications in Computer and Information Science > Emerging Research in Artificial Intelligence and Computational Intelligence > Expert and Decision Support Systems > 253-260

With the development of Internet120, the information on the Web is more and more abundance. In this paper, combining Mobile Agent theory and Context-aware, a kind of Context-ware model based on Mobile Agent has been brought forward. The function of analyzing actual requirement of users which combines their context information, utilizing Mobile Agent to aware, process and manage context information,...

Model of Trusted Dynamic Measurement Based on System Calls

Rui Hao, Xinguang Peng, Lei Xiu

Communications in Computer and Information Science > Emerging Research in Web Information Systems and Mining > Information Security > 238-241

The model of establishing the chain of trust presented by TCG is only the static integrity measure to system resources,it can not guarantee the dynamic trust after system operating. Therefore, this paper presents the trusted dynamic measurement model to platform application based on system calls for guaranteeing trust of the platform after computer system operating.

Trust-Based Scheduling Strategy for Workflow Applications in Cloud Environment

Yuli Yang, Xinguang Peng

2013 Eighth International Conference on P2P, Parallel, Grid, Cloud and Internet Computing > 316 - 320

2013 Eighth International Conference on P2P, Parallel, Grid, Cloud and Internet Computing (3PGCIC)

Current research on scheduling of workflow applications in Cloud environment is main focused on the trade-off between the execution cost and time of a task. However, unlike traditional scheduling, there are other important requirements to be taken into account. One such a requirement is trust scheduling, namely selecting trustful compute resources and data hosts so that the execution of applications...

Research of Software Trusted Dynamic Measurement Based on Support Vector Machine

Rui Hao, Xinguang Peng, Lei Xiu

2012 International Conference on Computing, Measurement, Control and Sensor Network > 401 - 404

2012 International Conference on Computing, Measurement, Control and Sensor Network (CMCS)

The research of software dynamic trusted measurement is one of the hot spots in trusted computing fields. To the existing problems of methods and theories in the credibility of the dynamic measurement for software, this paper puts forward to use dynamic extracting function return addresses in call stacks for obtaining system call short sequences. On this basis, the short sequences as the basic unit...

Research of software dynamic trusted measurement method

Rui Hao, Xinguang Peng, Lei Xiu

Proceedings of 2011 International Conference on Computer Science and Network Technology > 4 > 2614 - 2617

2011 International Conference on Computer Science and Network Technology (ICCSNT)

The research of software dynamic trusted measurement is one of the hot spots in trusted computing fields. In order to improve current dynamic trusted measurement theories and methods of software. The conceptions of behavior trace are proposed to depict the dynamic characteristics of software behavior. This method uses the chains of function return addresses to derive software normal behavior models...

The Application of Global Data Envelopment Analysis in the Disruption Management

Jiamin Wu, Xinguang Peng

2009 First International Workshop on Education Technology and Computer Science > 2 > 655 - 658

2009 First International Workshop on Education Technology and Computer Science. ETCS 2009

The increasing disasters have led to the development of the disruption management. It is important to attempt to measure the relative efficiency of the input and output, which are from a group of nearly homogeneous departments in the disruption. The global data envelopment analysis (GDEA) methodology enables to aggregate performance results in order to obtain an overall performance measure through...

Program Detection with Context Dependency for Collaborative Services

Xinguang Peng, Junfeng Zhang

2006 10th International Conference on Computer Supported Cooperative Work in Design > 1 - 6

Proceedings 2006 10th International Conference on Computer Supported Cooperative Work in Design

Anomaly detection of privileged programs is one of the most important means to ensure the security of collaborative services. The concept of the short sequences on the context dependency has been strictly defined, which as the computation foundation, can be introduced into the anomaly detection of privileged programs providing collaborative services. The method of program detection has been established...
