[ITK-users] Question about ShapeLabelObject attribute

[Zein Salah]

Hi,

i need to compute the maximum length of objects in a a LabelMap, i.e.
something like LabelGeometryImageFilter::GetMajorAxisLength.
Does any of the attributes of ShapeLabelObject stores this? Is there a
way to compute this from the existing attribute, preferably without
the need to compute perimeters?

One more question: what do binary principal moments of an object
practically mean?

thanks.
z.
