An Algorithm for Investigating the Structure of Material Surfaces

M. Toman, P. Procházka


The aim of this paper is to summarize the algorithm and the experience that have been achieved in the investigation of grain structure of surfaces of certain materials, particularly from samples of gold. The main parts of the algorithm to be discussed are:1. acquisition of input data,2. localization of grain region,3. representation of grain size,4. representation of outputs (postprocessing).


investigation of structure of material surfaces; transformation of images; Gaussian low-frequency filter; local equalization; probability distribution of grain size
