Hi, I need to use a nonlinear solver in OpenCV. Does OpenCV support it or I need to use 3rd lib such as Ceres or Dlib?

Thanks a lot.

There is this LMSolver in OpenCV.

You can find some example in the OpenCV source code, for instance. It should be something like supplying your functions to compute the errors vector and the Jacobian.
