![]()  | 
				inRansacReprojThreshold | Integer | 0 - ![]()  | 
				Maximum reprojection error in the RANSAC algorithm to consider a point as an inlier. Applies only to RANSAC. | 
![]()  | 
				inMaxIterations | Integer | 1 - ![]()  | 
				The maximum number of robust method iterations. | 
![]()  | 
				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. | |
![]()  | 
				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. |
