Detailed Description

SoStructureModelIndexQuantification3d engine

The SoStructureModelIndexQuantification3d engine indicates the relative prevalence of rods and plates.

For an introduction, see section Morphometry.

This engine indicates the relative prevalence of rods and plates in a 3D structure. As in the fragmentation case, SoStructureModelIndexQuantification3d uses measurement of surface convexity. An ideal plate, cylinder and sphere have Structure model index values of 0, 3 and 4 respectively.

This engine uses dilation of input binarised image as it has been shown in the fragmentation case. The parameter is the number of iterations of dilation performed with a structuring element of size 3.

The Structure Model index is given by :

$Structure ~ Model ~ index = 6\times(\frac{S_d \times V}{S^2})$

where $S$ is the object surface area before dilation and $Sd$ is the change in surface area caused by dilation. $V$ is the initial, undilated object volume.
