Automatic reading recognition of index instruments based on computer vision is studied in this paper according to the precision demand of the calibration system. The panel center can be obtained by the total least squares method. Then the skeleton of the pointer can be obtained with the panel center known. At last, an improved angle method based on the angle method and the distance method is proposed...
Along with simulation method's increase, the visualization simulation because of its good visualization effect, has become one of day by day current research hot topics. In airplane synthesis health management study, to realize the highly effective low cost simulation confirmation, needs to carry on the visualization simulation to the airplane essential component. Here has first established the airplane...
Neural network system with delayed feedback is considered. By employing the polynomial theorem to analyze the distribution of the roots to the associated characteristic equation, the conditions of ensuring the existence of Hopf bifurcation are given. The application to chaotic control is investigated, and some numerical simulations are carried out to illustrate the obtained results.
