|---|
Approximates points with a segment using Least Trimmed Error algorithm.
Applications
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.
| Name | Type | Range | Description | |
|---|---|---|---|---|
 |
inPoints | Point2DArray | Input points | |
|
inRange | Range* | Determines which array points take part in fitting process | |
|
inSeedSubsetSize | Integer | 2 - 10 | Number of points in one combination for getting a sample segment |
|
inEvalSubsetSize | Integer* | 3 -  |
Number of closest points used for evaluation of a sample segment, or Auto if seed points are to be used |
 |
