Detailed Description

Skeleton of 2D images.

vtkImageSkeleton2D should leave only single pixel width lines of non-zero-valued pixels (values of 1 are not allowed). It works by erosion on a 3x3 neighborhood with special rules. The number of iterations determines how far the filter can erode. There are three pruning levels: prune == 0 will leave traces on all angles... prune == 1 will not leave traces on 135 degree angles, but will on 90. prune == 2 does not leave traces on any angles leaving only closed loops. Prune defaults to zero. The output scalar type is the same as the input.

Member Function Documentation

static vtkImageSkeleton2D* vtkImageSkeleton2D::New (   )  [static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on. Reimplemented from vtkAlgorithm.

virtual const char* vtkImageSkeleton2D::GetClassName (   )  [virtual]

Reimplemented from vtkImageIterateFilter.

static int vtkImageSkeleton2D::IsTypeOf (  const char *  type  )  [static]

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeRevisionMacro found in vtkSetGet.h. Reimplemented from vtkImageIterateFilter.

virtual int vtkImageSkeleton2D::IsA (  const char *  type  )  [virtual]

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeRevisionMacro found in vtkSetGet.h. Reimplemented from vtkImageIterateFilter.

static vtkImageSkeleton2D* vtkImageSkeleton2D::SafeDownCast (  vtkObject *  o  )  [static]

Reimplemented from vtkImageIterateFilter.

void vtkImageSkeleton2D::PrintSelf (  ostream &  os, vtkIndent  indent )  [virtual]

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes. Reimplemented from vtkImageIterateFilter.

virtual void vtkImageSkeleton2D::SetPrune (  int   )  [virtual]

When prune is on, only closed loops are left unchanged.

virtual int vtkImageSkeleton2D::GetPrune (   )  [virtual]

virtual void vtkImageSkeleton2D::PruneOn (   )  [virtual]

virtual void vtkImageSkeleton2D::PruneOff (   )  [virtual]

void vtkImageSkeleton2D::SetNumberOfIterations (  int  num  )  [virtual]

Sets the number of cycles in the erosion. Reimplemented from vtkImageIterateFilter.

virtual int vtkImageSkeleton2D::IterativeRequestUpdateExtent (  vtkInformation *  in, vtkInformation *  out )  [protected, virtual]

Reimplemented from vtkImageIterateFilter.

void vtkImageSkeleton2D::ThreadedExecute (  vtkImageData *  inData, vtkImageData *  outData, int  outExt[6], int  id )  [protected, virtual]

Reimplemented from vtkThreadedImageAlgorithm.
