摘    要:利用三阶B样条函数来构造样条小波,结合二维离散二进小波的多孔算法及其Matlab软件编程,实现模极大边缘检测.对基于样条小波的模极大边缘检测算法与传统的Canny算法进行理论和实现效果上的比较,发现模极大边缘检测算法的效果明显好于Canny算法,当平滑尺度j=3时效果更好,可获得清晰的齿轮轮廓图形,解决了传统边缘检测算法效果差、识别价值低的问题.

关 键 词:齿轮  图像处理  边缘检测  小波  Canny算法

Abstract:In this paper,a spline wavelet is designed by using the cubic B-spline function and is then combined with the A'trous arithmetic of the 2D discrete binary wavelet and its Matlab programming to realize the edge detection of modular maximum.The proposed edge detection method based on the spline wavelet is theoretically and experimentally compared with the traditional Canny operator.It is found that the proposed method is of higher detection efficiency and can successfully solve the problems caused by the traditional edge detection method.An even better and clearer gear profile is obtained at a smoothing scale of j=3.
Keywords:gear  image processing  edge detection  wavelet  Canny operator
