Converts pixel data to surface data by using a threshold The mitkImageToSurfaceFilter is used to create a new surface out of an mitk image. The filter uses a threshold to define the surface. It is based on the vtkMarchingCube algorithm. By default a vtkPolyData surface based on an input threshold for the input image will be created. Optional it is possible to reduce the number of triangles/polygones [SetDecimate(mitk::ImageToSurfaceFilter::DecimatePro) and SetTargetReduction (float _arg)] or smooth the surface-data [SetSmooth(true), SetSmoothIteration(int smoothIteration) and SetSmoothRelaxation(float smoothRelaxation)].

Converts pixel data to surface data by using a threshold The mitkImageToSurfaceFilter is used to create a new surface out of an mitk image. The filter uses a threshold to define the surface.

The resulting vtk-surface has the same size as the input image. The surface can be generally smoothed by vtkDecimatePro reduce complexity of triangles and vtkSmoothPolyDataFilter to relax the mesh. Both are enabled by default and connected in the common way of pipelining in ITK. It's also possible to create time sliced surfaces.

With the given threshold vtkMarchingCube creates the surface. By default nothing a vtkPolyData surface based on a threshold of the input image will be created.

Enable the decimation filter to reduce the number of triangles in the mesh and produce a good approximation to the original image. The filter has support for vtk-5 and earlier versions. More detailed information check the vtkDecimatePro and vtkDecimate.

Enables vtkSmoothPolyDataFilter. With Laplacian smoothing this filter will relax the surface. You can control the Filter by manipulating the number of iterations and the relaxing factor.
void mitk::ImageToSurfaceFilter::SetSmoothIteration | ( | int | smoothIteration | ) |
Set the number of iterations that is used to smooth the surface. Used is the vtkSmoothPolydataFilter that uses the laplacian filter. The higher the number of iterations that stronger the smooth-result
smoothIteration | As smoothIteration default in that case 50 was chosen. The VTK documentation recommends small relaxation factors and large numbers of iterations. |
void mitk::ImageToSurfaceFilter::SetSmoothRelaxation | ( | float | smoothRelaxation | ) |
Set number of relaxation. Specify the relaxation factor for Laplacian smoothing. The VTK documentation recommends small relaxation factors and large numbers of iterations.
smoothRelaxation | As smoothRelaxation default in that case 0.1 was chosen. The VTK documentation recommends small relaxation factors and large numbers of iterations. |

Set desired TargetReduction of triangles in the range from 0.0 to 1.0. The destroyed triangles are in relation with the size of data. For example 0.9 will reduce the data set to 10%.

Threshold that is used to create the surface. All pixel in the input image that are higher than that value will be considered in the surface. The threshold referees to vtkMarchingCube. Default value is 1. See also SetThreshold (ScalarType _arg)
