vtkImageVariance3D Class Reference
#include <vtkImageVariance3D.h>
Detailed Description
Variance in a neighborhood.vtkImageVariance3D replaces each pixel with a measurement of pixel variance in a elliptical neighborhood centered on that pixel. The value computed is not exactly the variance. The difference between the neighbor values and center value is computed and squared for each neighbor. These values are summed and divided by the total number of neighbors to produce the output value.

Member Function Documentation
| static vtkImageVariance3D* vtkImageVariance3D::New | ( | ) | [static] |
Create an object with Debug turned off, modified time initialized to zero, and reference counting on.
Reimplemented from vtkImageSpatialAlgorithm.
| virtual const char* vtkImageVariance3D::GetClassName | ( | ) | [virtual] |
Reimplemented from vtkImageSpatialAlgorithm.
| static int vtkImageVariance3D::IsTypeOf | ( | const char * | name | ) | [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 vtkImageSpatialAlgorithm.
| virtual int vtkImageVariance3D::IsA | ( | const char * | name | ) | [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 vtkImageSpatialAlgorithm.
| static vtkImageVariance3D* vtkImageVariance3D::SafeDownCast | ( | vtkObject * | o | ) | [static] |
Reimplemented from vtkImageSpatialAlgorithm.
| void vtkImageVariance3D::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 vtkImageSpatialAlgorithm.
| void vtkImageVariance3D::SetKernelSize | ( | int | size0, | |
| int | size1, | |||
| int | size2 | |||
| ) |
This method sets the size of the neighborhood. It also sets the default middle of the neighborhood and computes the Elliptical foot print.
| virtual int vtkImageVariance3D::RequestInformation | ( | vtkInformation * | request, | |
| vtkInformationVector ** | inputVector, | |||
| vtkInformationVector * | outputVector | |||
| ) | [protected, virtual] |
Reimplemented from vtkImageSpatialAlgorithm.
| void vtkImageVariance3D::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.
| virtual int vtkImageVariance3D::RequestData | ( | vtkInformation * | request, | |
| vtkInformationVector ** | inputVector, | |||
| vtkInformationVector * | outputVector | |||
| ) | [protected, virtual] |
This is called by the superclass. This is the method you should override.
Reimplemented from vtkThreadedImageAlgorithm.
