Detailed Description

generate object boundaries from labelled volumes

takes as input a volume (e.g., 3D structured point set) of segmentation labels and generates on output one or more models representing the boundaries between the specified label and the adjacent structures. One or more label values must be specified to generate the models. The boundary positions are always defined to be half-way between adjacent voxels. This filter works best with integral scalar values. If ComputeScalars is on (the default), each output cell will have cell data that corresponds to the scalar value (segmentation label) of the corresponding cube. Note that this differs from vtkMarchingCubes, which stores the scalar value as point data. The rationale for this difference is that cell vertices may be shared between multiple cells. This also means that the resultant polydata may be non-manifold (cell faces may be coincident). To further process the polydata, users should either: 1) extract cells that have a common scalar value using vtkThreshold, or 2) process the data with filters that can handle non-manifold polydata (e.g. vtkWindowedSincPolyDataFilter). Also note, Normals and Gradients are not computed. If ComputeAdjacentScalars is on (default is off), each output point will have point data that contains the label value of the neighbouring voxel. This allows to remove regions of the resulting vtkPolyData that are adjacent to specific label meshes. For example, if the input is a label image that was created by running a watershed transformation on a distance map followed by masking with the original binary segmentation. For further details and images see the VTK Journal paper "Providing values of adjacent voxel with vtkDiscreteMarchingCubes" by Roman Grothausmann: http://hdl.handle.net/10380/3559 http://www.vtkjournal.org/browse/publication/975

Warning

This filter is specialized to volumes. If you are interested in contouring other types of data, use the general vtkContourFilter. If you want to contour an image (i.e., a volume slice), use vtkMarchingSquares.
