AVS.DetectEdges_AsPaths Method
Extracts subpixel-precise paths that represent continuous edges.
Namespace: | AvlNet |
---|---|
Assembly: | AVL.NET.dll |
Syntax
public static void DetectEdges_AsPaths ( AvlNet.Image inImage, AvlNet.EdgeFilter inEdgeFilter, float inStdDevX, float inEdgeThreshold, float inEdgeHysteresis, float inMaxJoiningAngle, float inJoiningDistanceBalance, float inMinEdgeLength, IList<AvlNet.Path> outEdges )
Parameters
Name | Type | Range | Default | Description | |
---|---|---|---|---|---|
inImage | AvlNet.Image | Image from which edges will be extracted. | |||
inEdgeFilter | AvlNet.EdgeFilter | Type of edge filter used for computing gradients. | |||
inStdDevX | float | <0.0f, INF> | 2.0f | Amount of horizontal smoothing used by the edge filter. Default value: 2.0f. | |
inEdgeThreshold | float | <0.0f, INF> | 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. | |
inMaxJoiningAngle | float | <0.0f, 180.0f> | 30.0f | Maximal allowed angle between edges being joined. Default value: 30.0f. | |
inJoiningDistanceBalance | float | <0.0f, 1.0f> | 0.0f | Determines how important distance between edges is according to their angle difference. Default value: 0.0f. | |
inMinEdgeLength | float | <0.0f, INF> | 0.0f | Minimal length of an edge. Default value: 0.0f. | |
outEdges | System.Collections.Generic.IList<AvlNet.Path> | Paths representing found edges. |
