It is suggested to estimate the processes intensity of plastic deformation, developed under the conditions of fatigue failure, with using of some numerical characteristics. These characteristics are obtained by two-dimensional power spectrum analysis of an optical surface images series. It is shown that the fatigue crack presence as a small-informative region on an image does not affect practically calculation results of the power spectrum energetic characteristics.
