Detailed Description

template<typename TInputImage, typename TOutput = double>
class itk::DiscreteGradientMagnitudeGaussianImageFunction< TInputImage, TOutput >

Compute the discrete gradient magnitude gaussian of an the image at a specific location in space, i.e. point, index or continuous index. This class computes a single derivative given the order in each direction (by default zero). This class is templated over the input image type.

The Initialize() method must be called after setting the parameters and before evaluating the function.
