SoDegreeOfAnisotropyQuantification engine
The SoDegreeOfAnisotropyQuantification engine measures a 3D symmetry
For an introduction, see section Morphometry.
This engine computes a measure of 3D symmetry. It is a good indicator to detect structural alignments along particular directional axis. This engine uses mean intercept length and eigen value analysis.
Mean intercept length analysis allows the user to measure isotropy of a structure. It proceeds sending a set of oriented ray through the binarised 3D image volume. For each ray, the number of objects encountered is counted. A set of discreet angles are processed as described and for each one an averaged is done by using a regularly spaced grid of rays. The SoDegreeOfAnisotropyQuantification::interceptDistance field is the distance between two lines intercept. The pitch angle is fixed at 10 degrees (not radians).
A classical eigen value analysis of this cloud of values (mean of number of intersect in function of angle) is then done. This analysis allows one to extract a minimal and a maximal eigen value. The closest these values are, the less the structural anisotropy is. Indeed maximum and minimum eigen values equality means that their is no privileged structural direction.
Degree of anisotropy is 0 for total isotropy and 1 for total anisotropy.
