 |
FitLineToPoints | Approximates points with a line using the Least Squares method. |
|
FitLineToPoints_M | Approximates points with a line using selected M-estimator for outlier suppression. Finding a locally optimal line. Good enough when the number of outliers is small. |
|
FitLineToPoints_RANSAC | Approximates points with a line using a RANSAC algorithm. Finds a well matching line, but for handling outliers requires a distance threshold that may be difficult to set. |
|
FitLineToPoints_TheilSen | Approximates points with a line using TheilSen algorithm, optionally with Siegel's improvement. Finds a well matching line, ignoring up to 29.3% (TheilSen) or 50.0% (Siegel) outliers. Outliers do have some influence on accuracy. |
|
FitLineToPoints_LTE | Approximates points with a line using Least Trimmed Error algorithm. Brute-force finding of a line that best matches a subset of the input points. Very efficient against outliers, but possibly slow for bigger subsets. |
