To investigate the characteristics of storm surge on Dongtou fishery port by the different tracks of typhoons, a series of numerical simulations is carried out by using the Delft3D model. The tidal level processes of 4 typhoons which passed by the fishery port on four different directions are analyzed. The results show that the simulated tidal level value is in a good agreement with the observed data...
The behavior recognition algorithm based on block matrix is proposed, which mainly includes six kinds of abnormal behavior of jumping, accelerated running, falling down, squatting, waving and bag. Firstly, inter frame difference method is applied to on video stream to extract contour features of the moving object and the mathematical morphology method was carried out to deal with it. Then block bilateral...
This study designed a path planning method based on fuzzy algorithm and genetic fuzzy algorithm for the security patrol robot. Firstly, the fuzzy algorithm design of path planning was introduced, it included making the obstacle avoidance control strategy, establishing fuzzy language and its membership function of input and output, establishing fuzzy control rules for path planning, and carrying on...
For traditional mean shift tracking algorithm based on histogram, tracking is failing when target appears under the complicated tracking conditions. It can't significantly distinguish color-similar targets and backgrounds. This thesis proposed a kind of Mean Shift tracking algorithm based on Spatiogram Corrected Background Weighted Histogram and offered detailed derivation of the new algorithm. It...
Overlapping community detection algorithm research is one of hot topics in current social network analysis. In this paper, we applied the idea of weighted label propagation to overlapping community detection algorithm design, and propose a weighted label propagation algorithm (WLPA). Moreover, in order to evaluate the performance results of various overlapping community detection algorithms, we put...
In recent years, the community structures in complex networks has become a research hotspot. In this paper, we focus on weighted networks and propose a unique algorithm on detecting overlapping communities of weighted networks based on central figure with considerable accuracy. In the algorithm, all the central figures are first extracted. Then to each central figure, nodes are absorbed by closures...
In order to achieve effective dissemination of the particle set and to overcome the degradation of standard particle filter tracking. Particle filter target tracking algorithm which was optimalized by scale and orientation adaptive Mean shift is proposed. Considering improved mean shift as an optimization mechanism of particle propagation, the particles can be effectively dispersed and clustering,...
A joint algorithm is proposed for computing embedding dimension and delay time in phase space reconstruction. This algorithm based on delay time window method and mutual information method takes delay time window length into consideration, the delay time and embedding dimension can be obtained simultaneity. In simulation, by using the extremely simple noise reduction method, this algorithm has good...
