// .NAME vtkImageLaplacian - Computes divergence of gradient.
|
||
|
|
// .SECTION Description
|
||
|
|
// 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.
