In this paper, a new algorithm is proposed to detect and recognize common road signs. Firstly, color segmentation and connected domain analysis are used for region of interest (ROI) detection and then we used the improved two-time Hough transform to separately determinate the circle center and radium of the road sign. Then the Weighted Hausdorff Distance is applied in the recognition of extracted...
Enterprise education is a new kind of educational method, which aim is cultivating the undergraduate students' consciousness of start undertaking, the psychological quality of start undertaking, the ability of start undertaking and the knowledge of start undertaking. Developing enterprise education in colleges is the new request for the reform and development of the social-economic development, a...
In this paper, propagation process of malicious code in computer networks are analyzed by discrete-state Markov model. Computer system without defense mechanism of virus in the networks can be classified: susceptible(S), quarantine(Q), infection(I) and health(H). But the state of computer system is varying. These varieties are only relative to the state at present, and are disrelated to the past state...
The multi-stage influence diagram theory and the game theory are introduced to maneuvering decisions in the multi-fighter cooperative air combat. A multi-stage influence diagram game model for n-stages decision is presented, and the decision is sequential and maneuvering. Firstly, principles that the multi-fighter cooperative air combat is divided into the air combat of several small teams are determined,...
Brain-computer interface (BCI) is a new type of man-machine interfaces and one of the key technologies of rehabilitation robot. In this paper, the BCI system structure, working principle and the key technology are discussed. The dummy matrix based on event-related potential P300 is designed, used the stimulation by the character matrix sequence, subjects produced the evoked electroencephalograph (EEG)...
As web information expands, vertical search engine plays a more and more important role in search industry. With ldquobeing the best in specialized utilization fieldrdquo in mind, we develop domain-specific 114 search engine based on domain characteristics. Four advantages have been embodied in 114 search engine: quick response, high accuracy in domain, a significant enhancement of correlations between...
In a two-node distributed multisensor system, some algorithms of track correlation can be transformed to a generalized classical assignment problem, and the generalized classical assignment is a combined optimization problem. The model of mean-field network is proposed in this paper to solve the problem. The experimental results illustrate that using the neural network to solve the generalized classical...
