| VariationalRefinement Class |
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)=∫ΩδΨ(EI)+γΨ(EG)+αΨ(ES), where EI,EG,ES are color constancy, gradient constancy and smoothness terms respectively. Ψ(s2)=sqrt(s^2+ϵ^2) is a robust penalizer to limit the influence of outliers.
