* \class MRFEnergyEdgeFidelity
* \brief This is the implementation of an edge preserving model for Markov denoising.
*
* This is the implementation of an edge fidelity model for Markov denoising, to be used for
* regularization. Energy is:
* \f[ \sum_{t \in \mathcal{V}_s} U(x_s, x_t) = \Phi(x_s-x_t) \f]
* with
* - \f$ x_s \f$ the label on site s
* - \f$ x_t \f$ the label on site t, a neighbor of s
* - \f$ \Phi \f$ an edge preserving function:
* \f[ \Phi(u) = \frac{u^2}{1+u^2} \f]
*
* This class is meant to be used in the MRF framework with the otb::MarkovRandomFieldFilter
*
* \ingroup Markov
