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!
