Class VariationalRefinement

Namespace

OpenCvSharp

Assembly

OpenCvSharp.dll

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 sum of color constancy, gradient constancy and smoothness terms.

Parameters

i0 InputArray

i1 InputArray

flowU InputOutputArray

flowV InputOutputArray
