FitSegmentToPoints


Header: FIL.h
Namespace: fil
Module: FoundationBasic

Approximates points with a segment using selected outliers suppression method.

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

Syntax

C++
C#
 
void fil::FitSegmentToPoints
(
	const ftl::Array<fil::Point2D>& inPoints,
	ftl::Optional<const fil::Range&> inRange,
	ftl::Optional<fil::MEstimator::Type> inOutlierSuppression,
	fil::Segment2D& outSegment,
	ftl::Optional<ftl::Array<fil::Point2D>&> outInliers = ftl::NIL
)

Parameters

Name Type Default Description
Input value inPoints const Array<Point2D>&
Input value inRange Optional<const Range&> NIL Determines which array points take part in fitting process
Input value inOutlierSuppression Optional<MEstimator::Type> NIL
Output value outSegment Segment2D&
Output value outInliers Optional<Array<Point2D>&> NIL

Optional Outputs

The computation of following outputs can be switched off by passing value ftl::NIL to these parameters: outInliers.

Read more about Optional Outputs.

Description

The orientation of the resulting outSegment is always between 0 and 180 degrees.

Examples

The resulting outSegment drawn with the input points, inOutlierSuppression = Auto.
