Detailed Description

Computes magnitude of the gradient.

Date:: 2003/01/09 19:21:05

Revision:: 1.35

vtkImageGradientMagnitude computes the gradient magnitude of an image. Setting the dimensionality determines whether the gradient is computed on 2D images, or 3D volumes. The default is two dimensional XY images.

Member Function Documentation

vtkImageGradientMagnitude* vtkImageGradientMagnitude::New ( ) [static]

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

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

Reimplemented from vtkImageToImageFilter.

int vtkImageGradientMagnitude::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 vtkImageGradientMagnitude::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.

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

Reimplemented from vtkImageToImageFilter.

void vtkImageGradientMagnitude::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 vtkImageGradientMagnitude::SetHandleBoundaries ( int ) [virtual]

If "HandleBoundariesOn" then boundary pixels are duplicated So central differences can get values.

virtual int vtkImageGradientMagnitude::GetHandleBoundaries ( ) [virtual]

If "HandleBoundariesOn" then boundary pixels are duplicated So central differences can get values.

virtual void vtkImageGradientMagnitude::HandleBoundariesOn ( ) [virtual]

If "HandleBoundariesOn" then boundary pixels are duplicated So central differences can get values.

virtual void vtkImageGradientMagnitude::HandleBoundariesOff ( ) [virtual]

If "HandleBoundariesOn" then boundary pixels are duplicated So central differences can get values.

virtual void vtkImageGradientMagnitude::SetDimensionality ( int ) [virtual]

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

virtual int vtkImageGradientMagnitude::GetDimensionality ( ) [virtual]

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

void vtkImageGradientMagnitude::ExecuteInformation ( vtkImageData * inData,

vtkImageData * outData

) [protected, virtual]

Reimplemented from vtkImageToImageFilter.

void vtkImageGradientMagnitude::ComputeInputUpdateExtent ( int inExt[6],

int outExt[6]

) [protected, virtual]

Reimplemented from vtkImageToImageFilter.

void vtkImageGradientMagnitude::ExecuteInformation ( ) [inline, protected, virtual]

Reimplemented from vtkImageToImageFilter.
Definition at line 84 of file vtkImageGradientMagnitude.h.
References vtkImageToImageFilter::ExecuteInformation().

void vtkImageGradientMagnitude::ThreadedExecute ( vtkImageData * inData,

vtkImageData * outData,

int extent[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.
