Video stabilization is a technology to remove the dithering between frames in a video sequence by motion estimation, motion filter and motion compensation. In this paper, we focus on the motion estimation (ME) step which is known as the most important part for a successful video stabilization system because the latter processing heavily relies on it. However, traditional ME methods mainly hypothesize...
In this paper, BP and RBF models for evaluating the running reliability of communication networks is presented on the basis of artificial neural network. The applicability of the two neural networks are investigated to the reliability of communication networks system. The study shows that the model established by BP network has a good general ability and a slow impending speed, on the other hand,...
An event-driven model for manufacturing execution system platform is introduced. Response mechanism based on event-driven inside platform is described, and event models are designed, which include two sub-modules as event configuration and event detection. At last, design and development method of event model is given to show the validity and practicability of the event-driven mechanism.
There is a great deal of information, which is pertinent to geographical location and difficult to manage using traditional management methods during the course of managing radio station. Web geographical information system (WEBGIS) can organize and deal with the above information effectively. Consequently, the WEBGIS of managing radio station, which is one of the sub-systems of the whole information...
The establishment of the likelihood model of state observation with a strong robustness is one of the core issues in the study of moving hand tracking. This paper is dedicated to building a robust likelihood model of state observation, and do some study by using the method of gaining feature points from frame images of human hand. Firstly, based on physiological models and camera projection principle,...
Image segmentation is an essential and important part in medical image processing. Conventional methods typically demand significant amounts of time and don??t lend to a natural interaction scheme with 3D volume. In this paper we present a novel interactive method for fuzzy connectedness segmentation. In our approach, the user freely specifies a seed point 3D location at regions of interest directly...
It is important for modern enterprise to backup business data. The heterogeneous databases and systems can be protected and stored by network data backup system. A design of XML-based GUI for cross platform backup system is proposed, by which user can centrally backup and restore data. The plug-in enabled architecture of the GUI can improve system compatibility, reliability and flexibility. Finally,...
This paper presents a new face recognition method based on the analysis of local features. Firstly, we can get the images of magnitude by means of analyzing face images with the Gabor wavelets. Secondly, the magnitude images are divided into blocks, then principle components analysis (PCA) could be directly used to all the blocks to construct the feature space. Finally, all the blocks of images are...
Relevance feedback (RF) proved an effect way to improve the precision and recall of 3D model retrieval. Unfortunately, through existing methods of RF, it is straightforward to find out whether a model is similar or not, but it is impossible to find out which local part is similar or not. The new partial method of RF proposed in this paper provides a good solution, in which not only the similar models...
More and more enterprises, organisations and governments have used and disturbed information in word documents, pdf etc. It makes easily to unauthorized copying and dissemination. According to DRM??s requirements that are high performance and feasible, we evaluated two common text watermarking methods for instructing practical applications, and proposed a new approach in text watermarking where inter-character...
Sensor network nodes have a very tight power budget and the power efficiency is the biggest design concern in sensor network circuits. A general-purpose processor (e.g. an ARM processor) is not efficient to execute encryption algorithms because it has no special instructions to support encryption operations, for example very often-used permutation operations. In the paper, we propose a low-power ASIC...
In order to solve the problem of inconsistent color appearance between different views, and subsequently influences on multi-view video coding, a color correction algorithm of multi-view video based on depth segmentation is proposed in this paper. Firstly, depth information in each view is calculated. Then, background and foreground region are separated with the depth information. Finally, correction...
Coexistence of multicasting and DiffServ is promising since the DiffServ module can provide a scalable QoS framework and multicasting can save network resources. Although several approaches of multicasting in DiffServ networks have been proposed in recent years, most of them concern only one or two problems that existed in this research area. In this paper, we propose an integrated approach for DiffServ...
Numerical simulation results of fKdV equation are illustrated in the forms of waterfall with Matlab. Matlab can solve many complicated engineering problem and the numerical results can be showed by its excellent graphics. The forced Kortewege-de Vries (fKdV) equation was regarded as a classical nonlinear model when the resonant flow was happened. Which involves a balance between non-linearity and...
The characteristics of scene text include the uneven lighting and the variability of character color which make scene text extraction more difficult than document image. In this paper, a novel scene text extraction method is proposed based on the independence between hue and lightness. We categorize text region into three types according to the composed color. Different color information is used to...
Since infrared images reflect the temperature-field distributing of vein??s embranchment of the face, expression recognition from them should focus on changes of thermal distribution on facial muscles and blood vessels, which caused by mood variety. These thermal changes can be regarded as texture features of images. Wavelet transform is a good tool to analyze multi-scale, multi- direction changes...
Electronic commerce has sprung up in this era and has provided enterprises of all sizes with unprecedented opportunities for economic growth. Initially, electronic commerce focused only on customer-to-business and business-to-business web interaction. With the emergence of business process management and service-oriented technology, the focus has shifted to the development of e-services that integrate...
Conceptual data models, being the tool of design databases, have been proposed. Information in real world application is often vague or ambiguous. Currently, less research has been done in modeling imprecision and uncertainty in conceptual data model. The UML (Unified Modeling Language), being a set of OO modeling notations and a standard of the Object Management Group (OMG), can be applied for many...
Fisher??s discriminant requires the inverse operation of high-order within-class scatter matrix [Sw] in the dimensionality reduction of feature vectors. The results may be inaccurate if [Sw] is close to singular. This paper presents another classification-oriented mapping method for the dimensionality reduction of high-dimensional feature vectors, based on the generalized cross product of multi-vectors...
This paper investigates a question for covering approximation spaces posed by Y. Ge and obtains some characterizations of granularity-wise separations in covering approximation spaces with approximation operators C2 and C2 (in the sense of K. Qin, Y. Gao and Z. Pei), These results will be helpful to give further applications of Pawlak rough set theory in pattern recognition and artificial intelligence.
