public static void DetectRidges_AsRegion ( Fil.Image inImage, Optional<Fil.Region> inRoi, float inStdDevX, Optional<float> inStdDevY, float inRidgeThreshold, float inRidgeHysteresis, Fil.Polarity inPolarity, int inMinBlobArea, Fil.Region outRidgeRegion )
Parameters
| Name | Type | Range | Default | Description | |
|---|---|---|---|---|---|
 | inImage | Fil.Image | Input image. | ||
| inRoi | Ftl.Optional<Fil.Region> | Region of interest. Default value: ftl::NIL. | ||
| inStdDevX | float | <0.0f, INF> | 3.0f | Smoothing standard deviation (horizontal). Default value: 3.0f. |
| inStdDevY | Ftl.Optional<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 | Fil.Polarity | |||
| inMinBlobArea | int | <0, INF> | 1 | Minimal area of a ridge blob. Default value: 1. |
 | outRidgeRegion | Fil.Region |
