所设计的自适应控制器既能保证闭环系统所有信号的全局有界性，又能使输出跟踪误差以指数速度收敛到零的一个小邻域内。 - Edge detection and contour tracking are very important in computer vision . because the single pixel edges are needed in computer vision , an algorithm of edge detection and contour tracking is proposed using the good local character and multi - scale character of wavelet transform in the dissertation . the fuzzy algorithm is applied to pick the model maximum points , so that the single pixel edge can be obtained
边缘检测和轮廓跟踪在计算机视觉中有着重要的地位，利用小波变换良好的时频域局部化特性和多尺度特性，针对计算机视觉中需要提取单像素的点线等边缘的需求，本文提出了一种基于小波变换的边缘检测和轮廓跟踪算法，通过真正的边缘点是模的局部极值点这一特点，应用模糊算法对模极大值点进一步筛选得到单像素级的边缘，并在边缘跟踪时，有效利用原图像的信息，通过在小邻域内寻找局部峰值对丢失弱边缘进行了补偿。 - In capter 2 , it is proved that the system possesses a global attractor and a two - side estimate for the fractal dimension of it is presented . in capter 3 , several different approximate intertial manifolds of the system are constructed by applying linear galerkin method , method of projecting operator and operator eigenvalue and successive iterative method , and it is proved that arbitary trajectory of the system enters into a small neighbourhood of the global attractor after large time . capter 4 studies the asymptotic attractor of the system by constructing a solution sequence which approaches to the global attractor of the equation in long time , and the dimentional estimate of the asymptotic attractor is given
