Thus, the inertia ratio is a measure -of deformation. In comparison to deformation, the inertia ratio has a low +of deformation. In contrast to deformation (which is computed from the +contour), inertia ratio is based on the integral over the cell area and thus +less prone to noise. In comparison to deformation, the inertia ratio has a low correlation to porosity. Shape-Out also allows to compute the principal inertia ratio which is the maximal inertia ratio that can be obtained by rotating the contour. Thus,
