/**
|
|
* @class vtkImageLaplacian
|
|
* @brief Computes divergence of gradient.
|
|
*
|
|
* vtkImageLaplacian computes the Laplacian (like a second derivative)
|
|
* of a scalar image. The operation is the same as taking the
|
|
* divergence after a gradient. Boundaries are handled, so the input
|
|
* is the same as the output.
|
|
* Dimensionality determines how the input regions are interpreted.
|
|
* (images, or volumes). The Dimensionality defaults to two.
