* \class FourierMellinDescriptorsImageFunction
* \brief Calculate the Fourier-Mellin descriptors in the specified
* neighborhood.
*
* Calculate the Fourier-Mellin descriptors over a specified neighborhood.
* The implemented equation is:
*
* D_{p, q}=|M_{p, q}|
*
* With:
*
* \f[ M_{p, q}=\frac{1}{2\pi} \int_{-\infty}^{\infty} \int_{-\infty}^{\infty} (x+iy)^{p} \cdot
(x^{2}+y^{2})^{\frac{p-2+\sigma-iq}{2}} \cdot f(x, y) \cdot dx \cdot dy \f]
*
* And:
* - \f$(x, y)\f$ pixel localization;
* - \f$ f(x, y)\f$ the pixel value over the \f$(x, y)\f$ coordinate.
*
* This class is templated over the input image type and the
* coordinate representation type (e.g. float or double).
*
* \ingroup ImageFunctions
