* \class MRFEnergyPotts
* \brief This is the implementation of the Potts model for Markov classification.
*
* This is the implementation of the Potts model for Markov classification, to be used for
* regularization. Energy is:
* \f[ U(x_s, x_t) = -\beta \textrm{ if } x_s = x_t \f]
* \f[ U(x_s, x_t) = +\beta \textrm{ if } x_s \neq x_t \f]
* with
* - \f$ x_s \f$ the label on site s
* - \f$ y_s \f$ the value on the reference image
* - \f$ \sigma^2_{x_s} \f$ the noise variance
*
* This class is meant to be used in the MRF framework with the otb::MarkovRandomFieldFilter
*
* \ingroup Markov

* \ingroup OTBMarkov
