AVL.DetectEdges_AsRegion_Mask(AvlNet.Image, AvlNet.Region, AvlNet.EdgeMaskFilter, float, float, float, int, AvlNet.Region)

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

Namespace:AvlNet
Assembly:AVL.NET.dll

Syntax


public static void DetectEdges_AsRegion_Mask(
	AvlNet.Image inImage,
	AvlNet.Region inRoi,
	AvlNet.EdgeMaskFilter inEdgeMaskFilter,
	float inEdgeThreshold,
	float inEdgeHysteresis,
	float inMaxJoiningDistance,
	int inMinBlobArea,
	out AvlNet.Region outEdgeRegion
)

Parameters

inImage
Type: AvlNet.Image
Image from which edges will be extracted
inRoi
Type: AvlNet.Region
Region of the image from which edges will be extracted, or null.
inEdgeMaskFilter
Type: AvlNet.EdgeMaskFilter
Type of edge filter used for computing gradients
inEdgeThreshold
Type: System.Single
Sufficient edge strength; edges of that strength will always be detected
inEdgeHysteresis
Type: System.Single
Value by which the edge threshold is decreased for edge points neighboring with sufficiently strong edges
inMaxJoiningDistance
Type: System.Single
Maximal distance between edges that can be joined
inMinBlobArea
Type: System.Int32
Minimal area of an edge blob
outEdgeRegion
Type: AvlNet.Region
Region of the found edges
