Segmentation of Pulmonary Nodules Using Fuzzy Clustering Based on Coefficient of Curvature
2013 Seventh International Conference on Image and Graphics (ICIG)
By Kan Chen,Bin Li,Lian-Fang Tian,Jing Zhang
Issue Date:July 2013
Pulmonary nodules are potential manifestation of lung cancer. Accurate segmentation of juxta-vascular nodules and ground glass opacity (GGO) nodules are an important and active area of research in medical image processing. At present, the classical segment...
A Modified Fuzzy C-means Algorithm in Remote Sensing Image Segmentation
Environmental Science and Information Application Technology, International Conference on
By Du Gen-yuan, Miao Fang, Tian Sheng-li, Liu Ye
Issue Date:July 2009
Fuzzy C-Means (FCM) algorithm has good clustering efficiency, for which it is widely used in the field of image segmentation. However, problems such as weak robustness of distance measure, the number of initial clustering to be given in advance and not con...
A Practical System of Domain Ontology Learning Using the Web for Chinese
Internet and Web Applications and Services, International Conference on
By Fang Tian, Peilin Jiang, Fuji Ren
Issue Date:May 2009
This paper proposes an ontology learning system model based on the Web search engine and Protege-OWL API, which emphasizes iterative learning approach by the extracted instances. We discuss taxonomic and non-taxonomic relationship learning separately in on...
The Research on the Ambiguous Path Identification Technology of Expressway Based on GIS
Software Engineering, World Congress on
By Wu Fang, Tian Zhihui, Zeng Yuhuai
Issue Date:May 2009
With the expressway forming the network, different construction costs of expressway sections cause the ambiguous path problems of the expressway network. The identification of the expressway ambiguous path is the key technology that relates to the expressw...
Research on AIN Applied to Information Fusion
International Conference on Natural Computation
By Hong Ge, Lian-Fang Tian
Issue Date:October 2008
Information fusion technology is a new method to integrate and manage multi-sensor data in order to obtain a more accurate detection or identification. With the improvement of intelligent level of modern technology, information fusion will become the inevi...
SIGF: a family of configurable, secure routing protocols for wireless sensor networks
Found in: Proceedings of the fourth ACM workshop on Security of ad hoc and sensor networks (SASN '06)
By Anthony D. Wood, John A. Stankovic, Lei Fang, Tian He
Issue Date:October 2006
As sensor networks are deployed in adversarial environments and used for critical applications such as battlefield surveillance and medical monitoring, security weaknesses become a big concern. The severe resource constraints of WSNs give rise to the need ...
Approach to Optimizing Restoration of Motion Blur Images with Robust Blind Deconvolution Based on New Cepstrum and Total Variation
Computer Science and Electronics Engineering, International Conference on
By Yuan-min Liu,Lian-fang Tian
Issue Date:March 2012
Blind deconvolution algorithms for blur images have been in widespread use for a decade. However most of the methods suffer from issues like processing speed defects, robustness, ill-posed ness. In view of the current research for blur images, a fast, robu...
Exergy Analysis of Transcritical Carbon Dioxide Refrigeration Cycle with an Ejector
Computer Distributed Control and Intelligent Environmental Monitoring, International Conference on
By Sun Fang-tian, Ma Yi-tai, Wei Yun-xia, Li De-ying
Issue Date:February 2011
The throttling loss is the major loss of the transcritical carbon dioxide refrigeration cycle, and the reason of low efficiency for performance. The study on the transcritical carbon dioxide refrigeration cycle with ejector and with throttling valve has be...
Study on an Improved Numerical Method of Seepage Analysis for Unsaturated Soil Slope
Electrical and Control Engineering, International Conference on
By Ming-tao Zhou, Wen-nian Xu, Dong-fang Tian
Issue Date:June 2010
Based on the governing equation of seepage, we investigates the influence of consolidation stress on unsaturated seepage in soil slope, considering the relationships among stress and strain, saturated permeability coefficient and soil porosity, and combini...
Self-Certified Proxy Blind Signcryption Scheme from Pairings
Network Computing and Information Security, International Conference on
By Yu Hui-fang, Tian Li-qin, Wang Zhi-cang
Issue Date:May 2011
By integrating the thoughts of self-certified signcryption and proxy blind signature, we propose a new self certified proxy blind signcryption scheme from pairings and prove its security in the random oracle model. The proposed overcomes the certificate ex...
