FIL.ScanSingleEdge

Locates the strongest transition between dark and bright pixels along a given path.

Namespace:FilNet
Assembly:FIL.NET.dll

Syntax

C++
C#
 
public static void ScanSingleEdge
(
	FilNet.Image inImage,
	FilNet.ScanMap inScanMap,
	FilNet.EdgeScanParams inEdgeScanParams,
	FilNet.Selection inEdgeSelection,
	out FilNet.Edge1D? outEdge,
	FilNet.Profile diagBrightnessProfile,
	FilNet.Profile diagResponseProfile
)

Parameters

Name Type Range Default Description
inImageFilNet.ImageInput image.
inScanMapFilNet.ScanMapData precomputed with CreateScanMap.
inEdgeScanParamsFilNet.EdgeScanParamsParameters controlling the edge extraction process.
inEdgeSelectionFilNet.Selectionfil::Selection::BestSelection mode of the resulting edge. Default value: fil::Selection::Best.
outEdgeFilNet.Edge1D?Found edge.
diagBrightnessProfileFilNet.ProfileExtracted image profile.
diagResponseProfileFilNet.ProfileProfile of the edge (derivative) operator response.

Description

The operation scans the image using inScanMap previously generated from a scan path and locates the strongest edge perpendicular to the path. If the strongest edge is weaker than inEdgeScanParams.minMagnitude then the outputs are set to NIL.

Examples

ScanSingleEdge locates the strongest edge using a scan map representing the scan path above.
