+There are various others user-intended packages :
+
+\paragraph{vtk}
+It contains some vtk based image processing filters :
+% \begin{enumerate}
+ \subparagraph{AppendPolyData}
+ Appends one of more polygonal datasets into a single polygonal dataset
+ \subparagraph{ConeSource}
+ Creates a Cone
+ \subparagraph{ImageAnisotropicDiffusion3D}
+vtkImageAnisotropicDiffusion3D diffuses an volume iteratively.
+The neighborhood of the diffusion is determined by the instance flags.
+if 'Faces' is on, the 6 voxels adjoined by faces are included in the neighborhood.
+If 'Edges' is on the 12 edge connected voxels are included, and if 'Corners' is on, the 8 corner connected voxels are included.
+'DiffusionFactor' determines how far a pixel value moves toward its neighbors, and is insensitive to the number of neighbors chosen.
+The diffusion is anisotropic because it only occurs when a gradient measure is below 'GradientThreshold'.
+Two gradient measures exist and are toggled by the 'GradientMagnitudeThreshold' flag.
+When 'GradientMagnitudeThreshold' is on, the magnitude of the gradient, computed by central differences, above 'DiffusionThreshold' a voxel is not modified.
+The alternative measure examines each neighbor independently.
+The gradient between the voxel and the neighbor must be below the 'DiffusionThreshold' for diffusion to occur with THAT neighbor.
+ \subparagraph{ImageCharacteristics}
+ Exports objet sizes, and Spacings
+ \subparagraph{ImageDilateErode3D}
+ Dilates one value and erodes another.
+ vtkImageDilateErode3D will dilate one value and erode another.
+ It uses an elliptical foot print, and only erodes/dilates on the boundary of the two values.
+ The filter is restricted to the X, Y, and Z axes for now.
+ It can degenerate to a 2 or 1 dimensional filter by setting the kernel size to 1 for a specific axis.
+ (bbfication of vtkImageDilateErode3D)
+ \subparagraph{ImageGaussianSmooth}
+ Performs a gaussian convolution of the input image
+ \subparagraph{ImagePlanes}
+Creates three 3D planes with the input image mapped onto with which the user can interact.
+The output vtkImagePlaneWidget objects are to be inserted into a 3D scene (e.g. a Viewer3D
+ \subparagraph{IsoSurfaceExtractor}
+Extracts an iso-surface of a 3D image and creates a vtkProp3D object to insert into a 3D scene (e.g. a Viewer3D
+ \subparagraph{MarchingCubes}
+ Extracts an iso-surface of an image using the marching cubes algorithm (bbfication of vtkMarchingCubes
+ \subparagraph{MIPCreator}
+Creates a Maximum Intensity Projection (MIP) view of a 3D image.
+Creates a vtkProp3D object to insert into a 3D scene (e.g. a Viewer3D
+ \subparagraph{MetaImageReader}
+Reads .mhd / .mhd image formats (bbfication of vtkMetaImageReader)
+ \subparagraph{SegmentationConnectivity}
+Segmentation with min max threshold and connectivity
+ \subparagraph{SphereSource}
+ Creates a Sphere
+% \end{enumerate}
+
+\paragraph{itk}
+It contains some itk based image processing filters :
+
+ \subparagraph{BinaryThresholdImageFilter}
+ Binarizes an image by thresholding (generic bbification of itk::BinaryThresholdImageFilter)
+ \subparagraph{DICOMSeriesFileNames}
+ Reads a series from a DICOM directory as a 3D itk image
+ \subparagraph{ExtractImageFilter}
+ Decrease the image size by cropping the image to the selected region bounds (bbification of itk::ExtractImageFilter)
+ \subparagraph{ImageProperties}
+ Outputs different properties of an image (type, dimension, size, spacing, ...)
+ \subparagraph{ImageRegion}
+Creates a generic ImageRegion (bbtk::any) from two vectors providing the index and size of the region.
+The dimension D of the actual itk::ImageRegion created is the max of the sizes of Index and Size
+(the smallest vector is padded by zeros)
+ \subparagraph{ImageReader}
+Generic itk image reader
+ \subparagraph{ImageWriter}
+Generic itk image writer
+ \subparagraph{ImageSeriesReader}
+Generic itk image series reader.
+ \subparagraph{ResampleImageFilter}
+Resamples an image
+\paragraph{itkvtk}
+It doesn't contain any end user intended box, only adaptors : to convert a generic itkImage to a vtkImageData, and vtkImageData* to a generic itkImage pointer
+
+Sorry nothing is done, right now for meshes.
+
+\paragraph{wxvtk}
+It contains two atomic black boxes, and some sophisticated complex black boxes :
+
+ \subparagraph{Viewer2D}
+ Receives a \textless vtkImageData* \textgreater (In), an Orientation(0:yz / 1:xz / 2:xy), and a initial slice number (Slice).
+ Returns a \textgreater vtkRenderer* \textgreater (Renderer)
+
+ \subparagraph{Viewer3D}
+ Receives up to 5 Input Actors (\textless vtkProp3D* \textgreater), up to 5 Imput Observers (\textless vtkInteractorObserver* \textgreater),
+ outputs an Interactor (\textless wxVTKRenderWindowInteractor* \textgreater) with which vtk widgets can interact,
+ and a Renderer (\textless vtkRenderer* \textgreater) to which actors can be added.
+ Has also a boolean 'Stereo' option, to use Red-Blue filter.
+
+ \subparagraph{Viewer3D}
