Detailed Description

Performs non-maximum suppression.

Date:: 2002/01/22 15:33:10

Revision:: 1.35

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

vtkImageNonMaximumSuppression* vtkImageNonMaximumSuppression::New ( ) [static]

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

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

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 vtkTypeRevisionMacro 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 vtkTypeRevisionMacro found in vtkSetGet.h.
Reimplemented from vtkImageTwoInputFilter.

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

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 vtkImageTwoInputFilter.

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

Set the magnitude and vector inputs.
Definition at line 61 of file vtkImageNonMaximumSuppression.h.
References vtkImageTwoInputFilter::SetInput1().

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

Set the magnitude and vector inputs.
Definition at line 62 of file vtkImageNonMaximumSuppression.h.
References vtkImageTwoInputFilter::SetInput2().

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)

void vtkImageNonMaximumSuppression::ExecuteInformation ( vtkImageData ** inDatas,

vtkImageData * outData

) [protected, virtual]

Reimplemented from vtkImageMultipleInputFilter.

virtual void vtkImageNonMaximumSuppression::ComputeInputUpdateExtent ( int inExt[6],

int outExt[6],

int whichInput

) [protected, virtual]

Reimplemented from vtkImageMultipleInputFilter.

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

Reimplemented from vtkImageMultipleInputFilter.
Definition at line 90 of file vtkImageNonMaximumSuppression.h.
References vtkImageMultipleInputFilter::ExecuteInformation().

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.
