Hi all,

I am using itkShapeLabelObject to compute the surface area of a segmented
object, in a 3D image. However, I have trouble understanding the
computation process from the code in
ITK/Modules/Filtering/LabelMap/include/itkShapeLabelMapFilter.hxx, which is
not documented anywhere else. Briefly, the algorithm goes througt the lines
of the LabelObject and looks at the intercepts. I don't understand how that
gives the parameter. Does anyone understood how it works?

Thanks for your help!
