<div class="block">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:
\(E(U) = \int_{\Omega} \delta \Psi(E_I) + \gamma \Psi(E_G) + \alpha \Psi(E_S) \),
where \(E_I,E_G,E_S\) are color constancy, gradient constancy and smoothness terms
respectively. \(\Psi(s^2)=\sqrt{s^2+\epsilon^2}\) 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</div>
