Hi everyone,<br><br>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.<br>
Any suggestion will be appreciated.<br>Thanks in advance,<br>Regrads,<br>wediong<br>
