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 *  name)
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 vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkImageIterateFilter.

virtual int vtkImageSkeleton2D::IsA ( const char *  name)
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 vtkTypeMacro 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

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

virtual void vtkImageSkeleton2D::PruneOn ( )
virtual

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

virtual void vtkImageSkeleton2D::PruneOff ( )
virtual

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

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 
)
protectedvirtual

Reimplemented from vtkImageIterateFilter.

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

Reimplemented from vtkThreadedImageAlgorithm.
