FIL.FitSegmentToStripe

Performs a series of 1D stripe detections and finds a segment that best matches the detected points.

Namespace:FilNet
Assembly:FIL.NET.dll

Syntax

C++
C#
 
public static void FitSegmentToStripe
(
	FilNet.Image inImage,
	FilNet.SegmentFittingMap inFittingMap,
	FilNet.StripeScanParams inStripeScanParams,
	FilNet.Selection inStripeSelection,
	float inMaxIncompleteness,
	out FilNet.Segment2D? outSegment,
	out FilNet.Segment2D? outLeftSegment,
	out FilNet.Segment2D? outRightSegment
)

Parameters

Name Type Range Default Description
inImageFilNet.ImageImage to fit segment to.
inFittingMapFilNet.SegmentFittingMapInput fitting map.
inStripeScanParamsFilNet.StripeScanParamsParameters controlling the stripe extraction process.
inStripeSelectionFilNet.Selectionfil::Selection::BestSelection mode of stripe. Default value: fil::Selection::Best.
inMaxIncompletenessfloat<0.0f, 0.999f>0.1fMaximal fraction of stripe points not found. Default value: 0.1f.
outSegmentFilNet.Segment2D?Fitted segment in the middle of found stripe.
outLeftSegmentFilNet.Segment2D?Fitted left segment.
outRightSegmentFilNet.Segment2D?Fitted right segment.

Description

The operation tries to fit a given segment to stripe present in the inImage image. Internally, it performs a series of scans with the ScanSingleStripe filter using inFittingMap previously generated from the object being fitted. The found points are then used to determine the actual position of the segment in the image. Only inMaxIncompleteness fraction of these scans may fail. If the fitting according to the given parameters is not possible, outSegment is set to Nil.

Examples

Fitting a segment to the dark stripe of a nail
(inStripeScanParams.Polarity = Dark).
