Description of rough surfaces using conformal equivalent structure concept: Part 2. Numerical approach

In our new approach, the notion of conformal equivalent structure is introduced by comparing the slope or gradient distributions of surface topography in 2D or 3D mode, respectively. The stereological approach described in Section 2 is, thus, confirmed by the numerical one which is proposed in this paper. The approach emphasizes the viability of the modeling and the limits observed in some practical applications of the study of rough surfaces via different approximation methods. The few divergences which have been noticed may be explained by the introduction of parameters such as skewness and kurtosis.
