vtkImageGradient - Computes the gradient vector.
Super Class: vtkImageFilter
Description:
vtkImageGradient computes the gradient vector of an image. The vector results are stored as scalar components. The Dimensionality determines whether to perform a 2d or 3d gradient. The default is two dimensional XY gradient. OutputScalarType is always float. Gradient is computed using central differences.
