In this paper, a novel discriminant analysis approach using Angular Fourier transform is proposed for face recognition. As a generalization of Fourier transform, the Angular Fourier transform is an important frequency-domain analysis technique. The proposed approach combines it with discriminant analysis method. First, this approach selects appropriate value of angle parameter for discrete Angular...
The authority management is one of the core content in all System, particularly the MIS. The realization of authority management can deal with some problems from the of fundamental, such as misoperation, misdeletion, and other human factors. It can ensure the data management in program all right, and the users of the system work "in place, but not offside." The research use ASP.NET and C#...
In materials science, effective tools are needed to organize and systematically analyze vast amounts of highly diverse materials data stored in heterogeneous databases. We have developed and deployed a data warehouse named materials data warehouse (MDW) as a tool to apply integrative approaches to the analysis of large materials data. Integration of a data warehouse enables the proper materials data...
Face recognition is one of the most challenging research topics in the field of pattern recognition and computer vision. To efficiently deal with this problem, a novel face recognition algorithm is proposed by using marginal manifold learning and SVM classifier. Extensive experiments show that the proposed algorithm performs much better than other well-known face recognition algorithms.
In order to response the increased competition, improve the correctness and timeliness of decision-making, enterprises need to make efficient data analysis techniques and methods used in competitive intelligence system. XML combines with Web data mining technology can effectively solve many problems faced by Web data mining, significantly improve the efficiency and effect of collection and analysis...
The reference presents a novel approach for Chinese character recognition. Based on it, we know that we can treat character recognition as an image matching problem. Compared with traditional OCR, the new approach for character recognition uniquely uses local invariant descriptors as a new feature extraction method. In this paper, we present a new local descriptor which combines the scale-invariant...
With the development of computer's communication and multimedia technologies, the amount of video data is enlarged at an explosive speed. How to realize the personal video service becomes a hot issue in video retrieval area. In this paper, a new retrieval approach is proposed base on the scene affective content evaluation. First, affective content evaluation values are computed by improved fuzzy comprehensive...
The processing system of network security event is a typical complicated system depending on the collaborative work of multi-agent system, and how to constructs the collaborative work platform is a common problem. In this paper, we designed collaboration system CPS4NSE with B/S structure to deal with a large number of events which are transacted by a large number of personnel. First of all, the deployment...
A major problem faced by automobile part industry is how to provide efficient and cost-effective responses to the unpredictable changes taking place in a global market. This problem is made difficult by the complexity of supply chain networks coupled with the complexity of individual manufacturing systems within supply chains. This paper thus provides an electronic supply chain management (E-SCM)...
