This paper studies the multi-input and multi-output discrete-time nonnegative edge synchronization of networked systems based on neighbors’ output information. The communication relationship among the edges of networked systems is modeled by well-known line graph. Two observer-based edge synchronization algorithms are designed, for which some necessary and sufficient synchronization conditions are...
Character segmentation is the area of image segmentation, which is the classical problem. Different researchers put forward different resolution algorithms, but mainly concentrate on whether the segmentation result is good or not. As for the distinct difference between the prospect and background of image, global threshold segmentation method is simplest, but it is not suitable for the image which...
According to the flight path planning problem in dynamic environment, this paper gives a method of analysis. First, the radar threat field based on Voronoi diagram is created, and the track performance indicators established based on radar threat cost and fuel cost. Then the dijkstra algorithm was improved, and the algorithm is used for path planning in dynamic environment‥ Finally, the simulation...
Considering the problem of multi unmanned aerial vehicle (UAV) cooperative tracking multi-UAV formation, a decentralized cooperative tracking control method is presented. Through the establishment of UAV particle motion model and the UAV formation model, the multi-UAV formation tracking motion model by using the consensus algorithm is established, then multi-UAV formation tracking method Based on...
In this paper, we proposed an automatic evaluation method for Chinese handwritten ability, research on information card design, algorithms of image processing and the index computation of automatic evaluation. Image processing includes distortions detecting, stretching detecting, image de-skewing and image enhancement, the index computation of automatic evaluation based on features of global character,...
