| Abstract: | In order to enhance the evaluation accuracy of surface morphology,the wavelet filtering is used to the analysis of surface morphology,in which the decomposing number is determined according to the filtering cutoff wavelength.The influences of different wavelet bases on the evaluation references and parameters of the surface morphology are compared,and the comparative analysis between the Gaussian filtering recommended by ISO and wavelet filtering is given.The results have shown that the wavelet reference is... |
