The analysis method of quotient space theorem is selected to study the wavelet transform and the conclusion is reduced that wavelet and quotient space theorem is accordant. The quotient space granularity computing theorem and wavelet transform being combined, presented the new segmentation algorithm, experimental results demonstrate that is useful and valid for complicated texture image segmentation.
In view of computer technology widespread application in building where all kinds of information convergence, proposing the building numerical information integration, which aims at impelling the level conformity information of building, providing the advantageous support for intelligent building, the ecologically-safe building, and the energy efficiency of building, exploring the new direction of...
Taking Asian-Pacific robot contest as the background and robot vision system as the object of research, the target recognition arithmetic based on color information is introduced. It proposed eight connection clustering arithmetic based on color double thresholds in HSI color space. H-S double threshold is discussed deeply and pixels classed based on table is used, so calculating of image segmentation...
The context transfer can improve handover performance effectively through avoid performing the entire protocol exchange with the mobile nodes from scratch, so it have received a lot of attention recently. This paper introduced the present research situation of context transfer, and proposed a security context transfer method for integrated space network, that enables authorized security context transfers...
The total variation flow is used to construct image nonlinear scale space by its structure preserved characteristics. The concept of divergence used in this model is mainly based on image gradient which is often computed in one order neighbor. This restricts the selection of scale parameters so that only diffusion time and weight of fidelity function can be used. Actually, the common sense of spatial...
Utilizing the advanced mobile technology and the space location information technology, we design to achieve the sharing of resources and data transmission, through computer and other mobile terminal equipment in the wireless environment. Integrating GIS, GPS, mobile communication and computer network technology, realize the mobile informationization of the industry and public information service...
Based on Discovery Feature Sub-space Model (DFSSM), this paper proposes a new web text clustering algorithm which characterizes self-stability and powerful antinoise ability. The definitions of cluster and distance measures in the concept space being given. It can distinguishes the most meaningful features from the Concept Space without the evaluation function. The application in the modern long-distance...
XML has become a de facto standard for data representation and exchange over the Internet. With the emergence of more and more XML documents, the clustering of XML documents has become an active research area. XML documents lie between structured data and unstructured data which describe both content and structure, so how to effectively cluster XML documents is a huge challenge. However, most of existing...
Computer science and technology are constantly changing, which results in the changing interface between computers and people. The integration of space science and computer science make space scientists gain some form of higher-level insight into massive data sets. So it is crucial to develop technology that supports presenting space data effectively. Scientific visualizationpsilas role in presenting...
Human detection is the task of finding presence and position of human beings in images, In this paper, we apply scale space theory to detection human in still images. By integrating scale space theory with histogram of oriented gradients(HOG), we designed a new feature descriptor called scale space histogam of oriented gradients (SS-HOG). SS-HOG focus on the multiple scale property of describe an...
A new content-based routing (CBR) approach called ROSE is proposed to realize CBR in very large-scale publish-subscribe systems. ROSE relies on a ring space where subscriptions and events are routed along distinct, albeit intersecting, partitions. An analytical model of ROSE is derived, and validated through simulation. The results from theoretical analysis, simulations, and experiments show that...
It explains the hierarchical architecture of Bluetooth technology, and states its technological characteristics and application environments. On this basis, the author proposed the method of replacing the wired communication medium with the Bluetooth wireless communication technology, as well as constructing a wireless manufacturing network under industrial environment. It is to realize wireless communication...
