Detailed Description

Computes divergence of gradient.

vtkimageLaplacian computes the Laplacian (like a second derivative) of a scalar image. The operation is the same as taking the divergence after a gradient. Boundaries are handled, so the input is the same as the output. Dimensionality determines how the input regions are interpreted. (images, or volumes). The Dimensionality defaults to two.

Member Function Documentation

vtkImageLaplacian* vtkImageLaplacian::New  )  [static]
 

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

Reimplemented from vtkAlgorithm.

virtual const char* vtkImageLaplacian::GetClassName  )  [virtual]
 

Reimplemented from vtkImageToImageFilter.

int vtkImageLaplacian::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 vtkImageToImageFilter.

virtual int vtkImageLaplacian::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 vtkImageToImageFilter.

vtkImageLaplacian* vtkImageLaplacian::SafeDownCast vtkObject o  )  [static]
 

Reimplemented from vtkImageToImageFilter.

void vtkImageLaplacian::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 vtkImageToImageFilter.

virtual void vtkImageLaplacian::SetDimensionality int   )  [virtual]
 

Determines how the input is interpreted (set of 2d slices ...)

virtual int vtkImageLaplacian::GetDimensionality  )  [virtual]
 

Determines how the input is interpreted (set of 2d slices ...)

void vtkImageLaplacian::ComputeInputUpdateExtent int  inExt[6],
int  outExt[6]
[protected, virtual]
 

Reimplemented from vtkImageToImageFilter.

void vtkImageLaplacian::ThreadedExecute vtkImageData inData,
vtkImageData outData,
int  ext[6],
int  id
[protected, virtual]
 

If the subclass does not define an Execute method, then the task will be broken up, multiple threads will be spawned, and each thread will call this method. It is public so that the thread functions can call this method.

Reimplemented from vtkImageToImageFilter.
