Syntax

public static void ImageRidges ( AvlNet.Image inImage, AvlNet.Polarity inPolarity, float inNoiseLevel, AvlNet.Region outRidges )
Parameters
| Name | Type | Range | Default | Description | |
|---|---|---|---|---|---|
 | inImage | AvlNet.Image | Input image. | ||
| inPolarity | AvlNet.Polarity | Specifies the type of ridges to be detected (Bright, Dark or Any). | ||
| inNoiseLevel | float | <0.0f, INF> | Defines how much stronger a pixel has to be than its neighbors to be deemed a ridge pixel. | |
 | outRidges | AvlNet.Region | Region of ridges. |
Description
The operation finds region of pixels being local ridges on the image inImage within specific region inRoi. For a pixel to be deemed a ridge pixel it is necessary to be stronger than both its neighbor pixels in at least one from four main directions (horizontal, vertical and two diagonals) by at least inNoiseLevel. Furthermore, the pixel value must be between inMinValue and inMaxValue.
