Computer Simulations, Image Analyses, and Reconstructions

Abstract

The evaluation of microstructural correlation functions via computer simulations is a two-step process. First, one must generate realizations of the random medium using a particular simulation method. Second, one must sample each realization for the correlation functions of interest and then average over all realizations to get the ensemble-averaged correlation functions. Similar sampling techniques can be used to extract correlation functions from images of real heterogeneous materials.
