“…In practice, this kind of calculation is prohibitively time-consuming, unless to use fast Fourier transforms [13], and thus various means of approaching the correlation function are proposed in the literature [10± 11]. In particular, in the work of Boitier et al [11], the comparison of different parts of an image is approached by calculating the quadratic error between the porosity values, u(x) and u(x+h), measured in two scanned regions of interest (ROI) which are distant of h:…”

Porous media are frequently encountered in chemical engineering processes. A prime requirement for an optimized design of these processes is a careful characterization of the porous medium structure. Among the few experimental techniques that can be used to this end, image analysis of consolidated samples proves to be an efficient but seldom used tool. It is currently applied in the fields of geology and materials science. The aim of this paper is to enlighten different examples of diagnostic applications of image analysis in the field of chemical engineering.
