cvEstimateAffinePartial2D


Module: OpenCV

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

Name Type Range Description

Input value
inMethod CvEstimateAffine2DMethod
Input value
inRansacReprojThreshold Integer 0 - Maximum reprojection error in the RANSAC algorithm to consider a point as an inlier. Applies only to RANSAC.
Input value
inMaxIterations Integer 1 - The maximum number of robust method iterations.
Input value
inConfidence Double Confidence level, between 0 and 1, for the estimated transformation. Anything between 0.95 and 0.99 is usually good enough. Values too close to 1 can slow down the estimation significantly. Values lower than 0.8-0.9 can result in an incorrectly estimated transformation.
Input value
inRefineIterations Integer 1 - Maximum number of iterations of refining algorithm (Levenberg-Marquardt). Passing 0 will disable refining, so the output matrix will be output of robust method.
Output value
outAffineTransformation Matrix
