/**
* \class FlusserPathFunction
* \brief Calculate the Flusser's invariant parameters.
*
* Calculate the Flusser's invariant over a path and defined as:
*
* - \f$ \psi_{1} = c_{11} \f$
* - \f$ \psi_{2} = c_{21} c_{12} \f$
* - \f$ \psi_{3} = Re (c_{20} c_{12}^{2} )\f$
* - \f$ \psi_{4} = Im (c_{20} c_{12}^{2} )\f$
* - \f$ \psi_{5} = Re (c_{30} c_{12}^{3} )\f$
* - \f$ \psi_{6} = Im (c_{30} c_{12}^{3} )\f$
* - \f$ \psi_{7} = c_{22} \f$
* - \f$ \psi_{8} = Re (c_{31} c_{12}^{2} )\f$
* - \f$ \psi_{9} = Im (c_{31} c_{12}^{2} )\f$
* - \f$ \psi_{10} = Re (c_{40} c_{12}^{4} )\f$
* - \f$ \psi_{11} = Im (c_{40} c_{12}^{4} )\f$
*
* With :
*
* \f[ c_{p, q}=\int \int (x+iy)^{p} \cdot (x-iy)^{q} \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).
