Volume calculations with MorpholibJ

Hi there,

Does anyone can tell me if it’s possible to obtain the difference in Volume between the volume an object and it’s equivalent ellipsoid? I would then go through my entire object list as determined by #morpholibj.

In this case, I would assume the ellipsoid not to contain entirely the object, so a simple subtraction of the two volumes would not do…

More simply, I would want to calculate V3 from this figure (Fig 4 in Isaac A et al, Material Science and Engineering 2008):
