Detailed Description

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

Compute the Gaussian derivatives of an the image at a specific location in space, i.e. point, index or continuous index.

Note: From ITK 5, the Evaluate member functions of this class are concurrent thread safe: It is safe to have multiple simultaneous Evaluate calls on a GaussianDerivativeImageFunction object.

This class is templated over the input image type.
