Detailed Description

Performs non-maximum suppression.

vtkImageNonMaximumSuppression Sets to zero any pixel that is not a peak. If a pixel has a neighbor along the vector that has larger magnitude, the smaller pixel is set to zero. The filter takes two inputs: a magnitude and a vector. Output is magnitude information and is always in doubles. Typically this filter is used with vtkImageGradient and vtkImageGradientMagnitude as inputs.

Member Function Documentation

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

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

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

Reimplemented from vtkThreadedImageAlgorithm.

static int vtkImageNonMaximumSuppression::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 vtkThreadedImageAlgorithm.

virtual int vtkImageNonMaximumSuppression::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 vtkThreadedImageAlgorithm.

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

Reimplemented from vtkThreadedImageAlgorithm.

void vtkImageNonMaximumSuppression::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 vtkThreadedImageAlgorithm.

void vtkImageNonMaximumSuppression::SetMagnitudeInput (  vtkImageData *  input  )  [inline]

Set the magnitude and vector inputs. Definition at line 47 of file vtkImageNonMaximumSuppression.h. References vtkImageAlgorithm::SetInput().

void vtkImageNonMaximumSuppression::SetVectorInput (  vtkImageData *  input  )  [inline]

Definition at line 48 of file vtkImageNonMaximumSuppression.h. References vtkImageAlgorithm::SetInput().

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

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

virtual int vtkImageNonMaximumSuppression::GetHandleBoundaries (   )  [virtual]

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

virtual void vtkImageNonMaximumSuppression::HandleBoundariesOn (   )  [virtual]

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

virtual void vtkImageNonMaximumSuppression::HandleBoundariesOff (   )  [virtual]

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

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

Determines how the input is interpreted (set of 2d slices or a 3D volume)

virtual int vtkImageNonMaximumSuppression::GetDimensionality (   )  [virtual]

Determines how the input is interpreted (set of 2d slices or a 3D volume)

virtual int vtkImageNonMaximumSuppression::RequestInformation (  vtkInformation *  , vtkInformationVector **  , vtkInformationVector *  )  [protected, virtual]

Reimplemented from vtkImageAlgorithm.

virtual int vtkImageNonMaximumSuppression::RequestUpdateExtent (  vtkInformation *  , vtkInformationVector **  , vtkInformationVector *  )  [protected, virtual]

Reimplemented from vtkImageAlgorithm.

virtual void vtkImageNonMaximumSuppression::ThreadedRequestData (  vtkInformation *  request, vtkInformationVector **  inputVector, vtkInformationVector *  outputVector, vtkImageData ***  inData, vtkImageData **  outData, int  extent[6], int  threadId )  [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 vtkThreadedImageAlgorithm.
