Thanks:
Thanks to C. Charles Law who developed this class.
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 floats. Typically this filter is used with vtkImageGradient and vtkImageGradientMagnitude as inputs.

Member Function Documentation

virtual const char* vtkImageNonMaximumSuppression::GetClassName   [virtual]
 

Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkImageTwoInputFilter.

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 vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkImageTwoInputFilter.

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 vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkImageTwoInputFilter.

vtkImageNonMaximumSuppression* vtkImageNonMaximumSuppression::New   [static]
 

Instantiate object with no start, end, or progress methods.

Reimplemented from vtkImageTwoInputFilter.

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 vtkImageMultipleInputFilter.

vtkImageNonMaximumSuppression* vtkImageNonMaximumSuppression::SafeDownCast vtkObject   o [static]
 

Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkImageTwoInputFilter.

virtual void vtkImageNonMaximumSuppression::SetDimensionality int    [virtual]
 

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

virtual void vtkImageNonMaximumSuppression::SetHandleBoundaries int    [virtual]
 

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

void vtkImageNonMaximumSuppression::SetMagnitudeInput vtkImageData   input [inline]
 

Set the magnitude and vector inputs.

void vtkImageNonMaximumSuppression::ThreadedExecute vtkImageData **    inDatas,
vtkImageData   outData,
int    extent[6],
int    id
[protected, virtual]
 

The execute method created by the subclass. This is kept public instead of protected since it is called from a non-member thread function.

Reimplemented from vtkImageMultipleInputFilter.
