AVL.GradientImage Method
Computes a gradient image with smoothing operator of any size. The output pixels are signed.
Namespace: | AvlNet |
---|---|
Assembly: | AVL.NET.dll |
Syntax
public static void GradientImage( AvlNet.Image inImage, AvlNet.Region inRoi, AvlNet.GradientOperator inOperator, float inStdDevX, float? inStdDevY, out AvlNet.Image outGradientImage )
Parameters
Name | Type | Range | Default | Description | |
---|---|---|---|---|---|
inImage | AvlNet.Image | Input image. | |||
inRoi | AvlNet.Region | Range of outGradientImage pixels to be computed. Default value: atl::NIL, or null. | |||
inOperator | AvlNet.GradientOperator | Defines how the gradient is computed. | |||
inStdDevX | float | <0.0f, INF> | 2.0f | Horizontal smoothing standard deviation. Default value: 2.0f. | |
inStdDevY | float? | <0.0f, INF> | Vertical smoothing standard deviation. Default value: atl::NIL, or null. | ||
outGradientImage | AvlNet.Image | Gradients of the image. |
Remarks
Please note that about a half of the pixels will be negative and in the preview windows they will be displayed as black.
