/** \class MeanReciprocalSquareDifferenceImageToImageMetric
* \brief Computes similarity between two objects to be registered
*
* This Class is templated over the type of the Images to be compared and
* over the type of transformation and Iterpolator to be used.
*
* This metric computes the sum of squared differences between pixels in
* the moving image and pixels in the fixed image after passing the squared
* difference through a function of type \f$ \frac{1}{1+x} \f$.
* Spatial correspondance between both images is established through a
* Transform. Pixel values are taken from the Moving image. Their positions
* are mapped to the Fixed image and result in general in non-grid position
* on it. Values at these non-grid position of the Fixed image are interpolated
* using a user-selected Interpolator.
*
* \ingroup RegistrationMetrics
