A new approach of concentric circle detection is proposed in this paper. Firstly, the image is preprocessed by denosing, edge detection, and then the circle centers are allocated by the gradient Hough transform, at last, the radius are detected by the improved one-dimensional Hough transform. The detection efficiency is enhanced by image discretization and reduced resolution ratio in the process of...
A new experimental teaching system for computer graphical course was presented. In the system, the students may design programs about graphical methods and submit the experimental data and pictures to database. The system may automatically grade results about students' experiment. The teacher can use handmade perusal. The system can not only educate students' ability of study and design, but also...
We presented a new experimental teaching system for digital image processing course. The students may design programs about image processing methods and submit the experimental data to database in the system. The system may automatically grade students' experimental results. The teacher can use handmade perusal. The system can educate students' ability of study and design. It may raise teacher's working...
with developments of the society and the economy, how the undergraduate can be cultivated to application-oriented talents meeting quickly the needs of the market, which has been the focus of attention of common universities. Based on analyzing about the necessity of cooperation between common universities and enterprises, we introduce the exploration of the application-oriented undergraduate talents'...
In this paper, based on the Dijkstra algorithm and its past improvements, a new improvement is proposed by considering the case of the nodes, reforming the feature matrix of precursor node, and adding a shortest path tree. The algorithm has its advantages on both reducing the number of repeated operations and reading the shortest path and the path length from the startpoint to all the other nodes...
In this paper, it is given a new method of solving the fuzzy linear programming-the basic line algorithm. Compared with the simplex method in solving the fuzzy linear programming currently, the basic line algorithm not only has its advantages on both data stability and anti-cycle and so on, but also shows superior on reducing the solving steps and having no need to calculate the checking figures....
A virtual work flow software used for law education is introduced. According to analyze the organization and work flow of judicial department that include forensic, procuratorate, police department and lawyer business, we discuss the design project and the function of system. This system is applicable for law education. The students may take a look at case movie and enter subjunctive judicial department...
This article uses the advanced wavelet theory to perform multi-criteria transformation on the medical CT image wavelet in order to obtain directive components. The improved wavelet threshold value law is combined with the wavelet homomorphism filter corresponding to the obtained directive components to remove noise and enhance image effect, finally resulting in the multi-scale (level) enhanced images...
