Abstract

The analysis of non planar surfaces, modelled by IR²xIR functions, has been made in previous works using stereological parameters and functions depending on the size of structuring element applied for image transformations like the grey level granulometries and roughness function.

This study has been carried on a topographical point of view. At first, different models of inundation for non planar surfaces are defined: one floods the relief by successive threshold and others flood simultaneously all catchment basins. Some parameters are chosen to follow the evolution of appeared relief in function of the level of inundation so as to characterize the topography of the non planar surface. Finally, this analysis by flooding transformation for SEM images and simulated images is tested and criticized.

Keywords : mathematical morphology, fractography, non planar surfaces, inundation, topography, topology
