Documentation for vtkImageVariance3D

vtkImageVariance3D - Variance in a neighborhood.

Description:

vtkImageVariance3D replaces each pixel with a measurement of pixel variance in a eliptical 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.

Methods:

	void vtkImageVariance3D ()
	void vtkImageVariance3D ()
	static vtkImageVariance3D *New ()
	const char *GetClassName ()
	void PrintSelf (unknown & ,vtkIndent )
	void SetKernelSize (int ,int ,int )
	void ExecuteImageInformation ()
	void ThreadedExecute (vtkImageData * ,vtkImageData * ,int ,int )

Detailed Method Descriptions:

This method sets the size of the neighborhood. It also sets the default middle of the neighborhood and computes the Elliptical foot print.
