Abstract

In this paper we propose a method to characterize and estimate the variations of a random convex set \(\varXi _0\) in terms of shape, size and direction. The mean n-variogram \(\gamma ^{(n)}_{\varXi _0}{:}(u_1\cdots u_n)\mapsto \mathbb {E}[\nu _d(\varXi _0\cap (\varXi _0-u_1)\cdots \cap (\varXi _0-u_n))]\) of a random convex set \(\varXi _0\) on \( \mathbb {R}^d\) reveals information on the \(n^{th}\) order structure of \(\varXi _0\). Especially we will show that considering the mean n-variograms of the dilated random sets \(\varXi _0\oplus rK \) by an homothetic convex family \(rK_{r>0}\), it’s possible to estimate some characteristic of the \(n^{th}\) order structure of \(\varXi _0\). If we make a judicious choice of K, it provides relevant measures of \(\varXi _0\). Fortunately the germ-grain model is stable by convex dilatations, furthermore the mean n-variogram of the primary grain is estimable in several type of stationary germ-grain models by the so called n-points probability function. Here we will only focus on the Boolean model, in the planar case we will show how to estimate the \( n^{th}\) order structure of the random vector composed by the mixed volumes \(^t(A(\varXi _0),W(\varXi _0,K))\) of the primary grain, and we will describe a procedure to do it from a realization of the Boolean model in a bounded window. We will prove that this knowledge for all convex body K is sufficient to fully characterize the so called difference body of the grain \(\varXi _0\oplus \breve{\varXi _0}\). we will be discussing the choice of the element K, by choosing a ball, the mixed volumes coincide with the Minkowski’s functional of \(\varXi _0\) therefore we obtain the moments of the random vector composed of the area and perimeter \(^t(A(\varXi _0),U(\varXi ))\). By choosing a segment oriented by \(\theta \) we obtain estimates for the moments of the random vector composed by the area and the Ferret’s diameter in the direction \(\theta \), \(^t((A(\varXi _0), H_{\varXi _0}(\theta ))\). Finally, we will evaluate the performance of the method on a Boolean model with rectangular grain for the estimation of the second order moments of the random vectors \(^t(A(\varXi _0),U(\varXi _0))\) and \(^t((A(\varXi _0), H_{\varXi _0}(\theta ))\).
