The Application Multi-scale Characteristics of the Rubber Gasket Image Edge Detection by Using Wavelet

This paper is based on the multi-scale analysis of the wavelet transform. By detecting the part modulus maximum of the planar wavelet transformation coefficient, it can acquire the image edge feature of the rubber gasket and demonstrate the feasibility and advantages of Gaussian function, especially the smoothing function. This method successfully retains the edge information of rubber gasket and clearly detects its defects. The experiment proves that this novel method is able to extract the image edge from industrial image which contains uncertain and unclear edges.
