estimateAffinePartial2D function

(Mat, Mat) estimateAffinePartial2D(
  1. VecPoint2f from,
  2. VecPoint2f to, {
  3. int method = RANSAC,
  4. double ransacReprojThreshold = 3,
  5. int maxIters = 2000,
  6. double confidence = 0.99,
  7. int refineIters = 10,
  8. OutputArray? inliers,
})

EstimateAffinePartial2D computes an optimal limited affine transformation with 4 degrees of freedom between two 2D point sets.
