....fraction and the set covariance, which can be easily estimated by their observed image counterparts. The resulting estimators are unbiased, and expressions for the variance can be obtained from Robbins theorem (e.g. Stoyan et al. 1987) Under mild ergodicity assumptions they are strongly consistent (Molchanov, 1997) as the observation window expands to the entire plane. Aggregate functionals such as the contact distribution and pair correlation function are of interest when fitting the Boolean model to a data image. Usually, estimation is hampered by edge e#ects, but minus sampling ideas (Ripley, 1988, ....

.... and mining engineering motivate the modelling of populations of (random) objects using Boolean random sets: a point pattern of germs is generated according to a Poisson point process and at each germ an object or grain is located which is an independent realisation of a random compact set (see [23, 24, 25]) Often experimental data are available which provide further information on the location of grains. One may know that certain locations are covered by grains, one may know certain locations are not covered by grains, one may know the number of grains covering a certain location or one may know ....

....which are not necessarily isotropic. A random set 0 having the same distribution as all i , i 1, is called the typical grain. The ensemble of the fully penetrable and uncorrelated grains = x i 2 (x i i ) where x i i = fx i y : y 2 i g, is called a Boolean model [11, 12]. If the underlying Poisson process is homogeneous, then we also say that is homogeneous. The total mass of , D) determines the mean total number of grains. Consider a Boolean model inside a region D.
