Locates the strongest pair of edges across a given path.
Namespace: | AvlNet |
---|---|
Assembly: | AVL.NET.dll |
Syntax
public static void ScanSingleStripe ( AvlNet.Image inImage, AvlNet.ScanMap inScanMap, AvlNet.StripeScanParams inStripeScanParams, AvlNet.Selection inStripeSelection, AvlNet.LocalBlindness? inLocalBlindness, INullable<AvlNet.Stripe1D> outStripe )
Parameters
Name | Type | Range | Default | Description | |
---|---|---|---|---|---|
![]() | inImage | AvlNet.Image | Input image. | ||
![]() | inScanMap | AvlNet.ScanMap | Data precomputed with CreateScanMap. | ||
![]() | inStripeScanParams | AvlNet.StripeScanParams | StripeScanParams ( ProfileInterpolation: Quadratic4 SmoothingStdDev: 0.6f MinMagnitude: 5.0f MaxInnerEdgeMagnitude: Nil StripePolarity: Dark MinStripeWidth: 0.0f MaxStripeWidth: Nil ) | Parameters controlling the stripe extraction process. Default value: StripeScanParams ( ProfileInterpolation: Quadratic4 SmoothingStdDev: 0.6f MinMagnitude: 5.0f MaxInnerEdgeMagnitude: Nil StripePolarity: Dark MinStripeWidth: 0.0f MaxStripeWidth: Nil ). | |
![]() | inStripeSelection | AvlNet.Selection | avl::Selection::Best | Selection mode of the resulting stripe. Default value: avl::Selection::Best. | |
![]() | inLocalBlindness | AvlNet.LocalBlindness? | Defines conditions in which weaker edges can be detected in the vicinity of stronger edges. Default value: atl::NIL. | ||
![]() | outStripe | AvlNet.INullable<AvlNet.Stripe1D> | Found stripe. This parameter cannot be null. |
Description
The operation scans the image using inScanMap previously generated from a scan path and locates the strongest stripe (i.e. a pair of opposite-polarity edges running across the path) of the given characteristics. If there is no such stripe then the outputs are set to NIL.
Examples
