AVL.ScanSingleStripe Method
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, out AvlNet.Stripe1D? outStripe )
Parameters
Name | Type | Range | Default | Description | |
---|---|---|---|---|---|
![]() | inImage | AvlNet.Image | Input image. | ||
![]() | inScanMap | AvlNet.ScanMap | Data precomputed with CreateScanMap. | ||
![]() | inStripeScanParams | AvlNet.StripeScanParams | Parameters controlling the stripe extraction process. | ||
![]() | 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, or null. | ||
![]() | outStripe | AvlNet.Stripe1D? | Found stripe. |
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
