Set-valued means of random particles
Planar images of powder particles or sand grains can be interpreted as ``figures'', i.e., equivalence classes of directly congruent compact sets. The paper introduces a concept of set-valued means and real-valued variances for samples of such figures. In obtaining these results, the images are registered to have similar locations and orientations. The method is applied to find a mean figure of a sample of polygonal particles.
