  abstract =   "In general three-dimensional segmentation algorithms assume
               objects to have connected homogeneous regions. However in
               some cases objects are defined by a fuzzy boundary surface
               and consist of an inhomogeneous internal structure. In the
               following a new three-dimensional segmentation technique
               exploiting the contour detection capabilities of live-wire
               is proposed: The algorithm consists of two basic steps.
               First contours are outlined by the user on a small number of
               planar cross-sections through the object using live-wire.
               Second the traced contours are used for reconstructing the
               object surface automatically in each slice using live-wire
               again. This user-friendly segmentation algorithm is
               independent from object topology as the topology is
               implicitly                  defined during the
               reconstruction process.",
