A novel approach to three-dimensional segmentation, parametric surface representation, and interactive surface modification is reported. The combination of shape-based and appearance-based volumetric segmentation, parametric representation of 3D surfaces, and their interactive modification and editing forms a very powerful paradigm for a variety of volumetric segmentation tasks. Performance assessment of the method for automated segmentation of diaphragm surfaces in volumetric 3D CT images is ongoing.
