[Insight-users] label object manipulation

Dear Gaëtan Lehmann,


Thanks  a  lot  for You quick answer. With Your hints it was easy to extend my
little program to suit my needs further.
I'm wondering though if the article is the best documentation to work with.  I
couldn't   find   the   Perimeter   attribute   only  EquivalentPerimeter  and
EquivalentEllipsoidPerimeter. The connectivity is also only mentioned  in  the
examples.  Is there another documentation where these are explained and that I
should read before asking here?

In the footnote it says there'll be more about perimeter estimation in another
article. Is that published already?

I  noticed  that GetEquivalentEllipsoidSize yields nan/inf if the bounding box
is only 1 pixel wide. When I used the image moments of Avizo to calculate  the
axes lengths a bounding box width of 1 pixel wasn't a problem. I'm not sure if
this result from Avizo is good but with my current understanding a  full  axis
length of 1 (or 0.5 for a semi axis) would be sensible, wouldn't it?
If  it's not possible to calculate that, would it be possible to get an output
letting the filter assume only 2D for these objects?

Kind regards,
Lynx
