Estimates global motion between two 2D point clouds.

Parameters

  points0 | Source set of 2D points (32F).
  points1 | Destination set of 2D points (32F).
  ok | Indicates whether motion was estimated successfully.

Returns
  3x3 2D transformation matrix (32F).

Implements cv::videostab::MotionEstimatorBase.
