3D image multifractal analysis and pore detection on a stereometric measurement file of a ceramic coating

Intensive work is carried out both on improving the existing test equipment as well as on developing new methods of surface modelling and analysis. Modern methods of surface topography analysis enable to obtain high-quality three-dimensional images of a surface. The analysis of spatial images is an important issue applied, inter alia, in materials science, robotics, medicine or in the development of satellite images. For people dealing with fractal description, it means computer calculations with the aim of obtaining fractal dimensions from the record representing the studied processes. The resulting dimensions are designed to detect the characteristics of the analysed object. In the paper, multifractal analysis of stereometric files was carried out, whose aim was to determine the locations of the most likely presence of pores on alumina ceramic coating surfaces.
