[Insight-users] Hi everyone about volume fraction from levelset

[Wei-Dong Lian]

Hi everyone,

I am employing LevelSet Image segmentation to segmente a 3D image for a
two-phases material and then predict the volume fraction of each phase. The
problem is that , for example, I know eight levelset values of corner points
of a cube. So theoretically, we could get the zero level set surface by
which the cube was divided into two phases, so we could have the volume
fraction of one phase. Now I am wondering if these exists some formulas to
do this, or in itk these exists some "objects" to calculate the volume
fraction.
Any suggestion will be appreciated.
Thanks in advance,
Regrads,
wediong
