Icon Name Description
FitSegmentToPoints Approximates points with a segment using selected outliers suppression method.

Finding a locally optimal segment. Good enough when the number of outliers is small.

FitSegmentToPoints_RANSAC Approximates points with a segment using a RANSAC algorithm.

Finds a well matching segments, but for handling outliers requires a distance threshold that may be difficult to set.

FitSegmentToPoints_TheilSen Approximates points with a segment using TheilSen algorithm, optionally with Siegel's improvement.

Finds a well matching segment, ignoring up to 29.3% (TheilSen) or 50.0% (Siegel) outliers. Outliers do have some influence on accuracy.

FitSegmentToPoints_LTE Approximates points with a segment using Least Trimmed Error algorithm.

Brute-force finding of a segment that best matches a subset of the input points. Very efficient against outliers, but possibly slow for bigger subsets.
