FIL.ScanSingleStripe

Locates the strongest pair of edges across a given path.

Namespace:FilNet
Assembly:FIL.NET.dll

Syntax

C++
C#
 
public static void ScanSingleStripe
(
	FilNet.Image inImage,
	FilNet.ScanMap inScanMap,
	FilNet.StripeScanParams inStripeScanParams,
	FilNet.Selection inStripeSelection,
	INullable<FilNet.Stripe1D> outStripe
)

Parameters

Name Type Range Default Description
inImageFilNet.ImageInput image.
inScanMapFilNet.ScanMapData precomputed with CreateScanMap.
inStripeScanParamsFilNet.StripeScanParamsStripeScanParams ( ProfileInterpolation: Quadratic4 SmoothingStdDev: 0.6f MinMagnitude: 5.0f MaxInnerEdgeMagnitude: Nil StripePolarity: Dark MinStripeWidth: 0.0f MaxStripeWidth: Nil )Parameters controlling the stripe extraction process. Default value: StripeScanParams ( ProfileInterpolation: Quadratic4 SmoothingStdDev: 0.6f MinMagnitude: 5.0f MaxInnerEdgeMagnitude: Nil StripePolarity: Dark MinStripeWidth: 0.0f MaxStripeWidth: Nil ).
inStripeSelectionFilNet.Selectionfil::Selection::BestSelection mode of the resulting stripe. Default value: fil::Selection::Best.
outStripeFilNet.INullable<FilNet.Stripe1D>Found stripe. This parameter cannot be null.

Description

The operation scans the image using inScanMap previously generated from a scan path and locates the strongest stripe (i.e. a pair of opposite-polarity edges running across the path) of the given characteristics. If there is no such stripe then the outputs are set to NIL.

Examples

ScanSingleStripe locates the strongest stripe using a scan map representing the scan path above.
