AVL.SegmentImage_Edges Method

Segments an image into blobs using image edges as their borders.

Namespace:	AvlNet
Assembly:	AVL.NET.dll

Syntax

public static void SegmentImage_Edges(
	AvlNet.Image inImage,
	AvlNet.Region inRoi,
	int inFrameSize,
	float inStdDev,
	float inEdgeThreshold,
	float inEdgeHysteresis,
	float inMaxJoiningDistance,
	int inMinArea,
	int? inMaxArea,
	bool inComputeNestingLevels,
	out AvlNet.Region[] outBlobs,
	out int[] outNestingLevels,
	out AvlNet.Region diagEdgeRegion
)

Parameters

Name	Type	Range	Default	Description
inImage	AvlNet.Image			Image from which blobs are extracted.
inRoi	AvlNet.Region			Range of pixels to be processed. Default value: atl::NIL, or null.
inFrameSize	int	<0, INF>	1	How many pixels form the image border are excluded from the results. Default value: 1.
inStdDev	float	<0.0f, INF>	2.0f	Amount of smoothing used by the edge filter. Default value: 2.0f.
inEdgeThreshold	float		15.0f	Sufficient edge strength; edges of that strength will always be detected. Default value: 15.0f.
inEdgeHysteresis	float	<0.0f, INF>	5.0f	Value by which the edge threshold is decreased for edge points neighboring with sufficiently strong edges. Default value: 5.0f.
inMaxJoiningDistance	float	<0.0f, INF>	0.0f	Maximal distance between edges that can be joined. Default value: 0.0f.
inMinArea	int	<0, INF>	50	Minimal area of a detected blob. Default value: 50.
inMaxArea	int ?	<0, INF>		Maximal area of a detected blob. Default value: atl::NIL, or null.
inComputeNestingLevels	bool			Flag indicating whether nesting levels should be computed.
outBlobs	AvlNet.Region			Blobs extracted from the input image.
outNestingLevels	int			Nesting level of each extracted blob
diagEdgeRegion	AvlNet.Region			Region of the found edges.
