FIS.DetectEdges_AsRegion_Mask Method

Extracts a pixel-precise region of continuous edges. Faster, yet less accurate version.

Namespace:FilNet
Assembly:FIL.NET.dll

Syntax

public static void DetectEdges_AsRegion_Mask
(
	FilNet.Image inImage,
	NullableRef<FilNet.Region> inRoi,
	FilNet.EdgeMaskFilter inEdgeMaskFilter,
	float inEdgeThreshold,
	float inEdgeHysteresis,
	float inMaxJoiningDistance,
	int inMinBlobArea,
	FilNet.Region outEdgeRegion,
	FilNet.Image diagGradientMagnitudeImage
)

Parameters

Name Type Range Default Description
inImageFilNet.ImageImage from which edges will be extracted.
inRoiFilNet.NullableRef<FilNet.Region>Region of the image from which edges will be extracted. Default value: ftl::NIL.
inEdgeMaskFilterFilNet.EdgeMaskFilterType of edge filter used for computing gradients.
inEdgeThresholdfloat<0.0f, INF>35.0fSufficient edge strength; edges of that strength will always be detected. Default value: 35.0f.
inEdgeHysteresisfloat<0.0f, INF>15.0fValue by which the edge threshold is decreased for edge points neighboring with sufficiently strong edges. Default value: 15.0f.
inMaxJoiningDistancefloat<0.0f, INF>0.0fMaximal distance between edges that can be joined. Default value: 0.0f.
inMinBlobAreaint<0, INF>1Minimal area of an edge blob. Default value: 1.
outEdgeRegionFilNet.RegionRegion of the found edges.
diagGradientMagnitudeImageFilNet.ImageVisualization of the gradient magnitude.
