Defining the criteria to select the wavelet type for the assessment of surface quality

Preliminary notesThe paper deals with one of the most important problems in the wavelet analysis -the methodology for mother wavelet selection.In this study, the surface texture of machine parts was assessed applying a wavelet transform.The calculations involved in roughness profile evaluation were based on three selection criteria: an autocorrelation test, a cross-correlation function and an entropy-based test.All the calculations and diagrams were produced using the Wavelet toolbox of the MATLAB package.
