Presents an image as being composed of the std::exp() of its pixels.
static void Set(TInternalType &output, const TExternalType &input)
Give access to the std::exp() function of a value.
~ExpNegativeImageAdaptor() override=default
Give access to partial aspects of voxels from an Image.
Base class for most ITK classes.
Definition: itkObject.h:60
