public class EllipsoidFactorWrapper
extends BoneJCommand
ImageJ plugin to describe the local geometry of a binary image in an
oblate/prolate spheroid space. Uses Skeletonize3D to generate a 3D skeleton
and/or a distance ridge-based image to generate seed points, which are used
as centres for maximally inscribed ellipsoids.
The ellipsoid factor (EF) is a method for the local determination of the rod-
or plate-like nature of porous or spongy continua. EF at a point within a 3D
structure is defined as the difference in axis ratios of the greatest
ellipsoid that fits inside the structure and that contains the point of
interest, and ranges from −1 for strongly oblate (discus-shaped) ellipsoids,
to +1 for strongly prolate (javelin-shaped) ellipsoids. For an ellipsoid with
axes a ≤ b ≤ c, EF = a/b − b/c.
