Abstract
Within the approach of physical mesomechanics of materials, a new method is proposed for numerical evaluation of surface-degradation processes (due to plastic deformation, electromigration, fatigue failure, etc.). Numerical characteristics of wavelet spectra and their two-dimensional graphical representation can be used both to estimate the quality and improve optical images (at the stage of preprocessing) and to analyze changes that occur under external loads applied to examined materials (at the stage of image analysis (recognition)).
