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.

Key words: gear, image processing, edge detection, wavelet, Canny operator
