FIS.DetectRidges_AsRegion Method
Extracts a pixel-precise region of bright or dark thin lines.
Namespace: | FilNet |
---|---|
Assembly: | FIL.NET.dll |
Syntax
public static void DetectRidges_AsRegion ( FilNet.Image inImage, NullableRef<FilNet.Region> inRoi, float inStdDevX, float? inStdDevY, float inRidgeThreshold, float inRidgeHysteresis, FilNet.Polarity inPolarity, int inMinBlobArea, FilNet.Region outRidgeRegion )
Parameters
Name | Type | Range | Default | Description | |
---|---|---|---|---|---|
![]() | inImage | FilNet.Image | Input image. | ||
![]() | inRoi | FilNet.NullableRef<FilNet.Region> | Region of interest. Default value: ftl::NIL. | ||
![]() | inStdDevX | float | <0.0f, INF> | 3.0f | Smoothing standard deviation (horizontal). Default value: 3.0f. |
![]() | inStdDevY | float? | <0.0f, INF> | Smoothing standard deviation (vertical, or Auto = horizontal). Default value: ftl::NIL. | |
![]() | inRidgeThreshold | float | <0.0f, INF> | 5.0f | Sufficient ridge strength; ridges of that strength will always be detected. Default value: 5.0f. |
![]() | inRidgeHysteresis | float | <0.0f, INF> | 4.0f | Value by which the ridge threshold is decreased for ridge points neighboring with sufficiently strong edges. Default value: 4.0f. |
![]() | inPolarity | FilNet.Polarity | |||
![]() | inMinBlobArea | int | <0, INF> | 1 | Minimal area of a ridge blob. Default value: 1. |
![]() | outRidgeRegion | FilNet.Region |
