|

|
|
* @brief 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.
