public static class opencv_optflow.VariationalRefinement
extends opencv_video.DenseOpticalFlow

\brief Variational optical flow refinement

This class implements variational refinement of the input flow field, i.e. it uses input flow to initialize the minimization of the following functional: \f$E(U) = \int_{\Omega} \delta \Psi(E_I) + \gamma \Psi(E_G) + \alpha \Psi(E_S) \f$, where \f$E_I,E_G,E_S\f$ are color constancy, gradient constancy and smoothness terms respectively. \f$\Psi(s^2)=\sqrt{s^2+\epsilon^2}\f$ is a robust penalizer to limit the influence of outliers. A complete formulation and a description of the minimization procedure can be found in \cite Brox2004
