| Name | Type | Description | |
|---|---|---|---|
 |
inPoints | Point2DArray | Input Point2D array. |
|
inDistType | CvDistanceType | Distance used by the M-estimator. |
|
inParam | Real | Numerical parameter [ C ] for some types of distances. If it is 0, an optimal value is chosen. |
|
inReps | Real | Sufficient accuracy for the radius [distance between the coordinate origin and the line]. |
|
inAeps | Real | Sufficient accuracy for the angle. 0.01 would be a good default value for reps and aeps. |
