AVL.ErodeImage Method
Replaces each pixel with the minimum of pixels within a kernel.
Namespace: | AvlNet |
---|---|
Assembly: | AVL.NET.dll |
Syntax
public static void ErodeImage( AvlNet.Image inImage, AvlNet.Region inRoi, AvlNet.Region inSourceRoi, AvlNet.Pixel? inBorderColor, AvlNet.ImageMorphologyKernel inKernel, int inRadiusX, int? inRadiusY, out AvlNet.Image outImage )
Parameters
Name | Type | Range | Default | Description | |
---|---|---|---|---|---|
inImage | AvlNet.Image | Input image. | |||
inRoi | AvlNet.Region | Range of outImage pixels to be computed. Default value: atl::NIL, or null. | |||
inSourceRoi | AvlNet.Region | Range of inImage pixels to be considered in computations. Default value: atl::NIL, or null. | |||
inBorderColor | AvlNet.Pixel? | Color of the imaginary pixels outside the image boundaries. Default value: atl::NIL, or null. | |||
inKernel | AvlNet.ImageMorphologyKernel | Kernel shape. | |||
inRadiusX | int | <0, INF> | 1 | Nearly half of the kernel's width (2*R+1). Default value: 1. | |
inRadiusY | int? | <0, INF> | Nearly half of the kernel's height (2*R+1), or same as inRadiusX. Default value: atl::NIL, or null. | ||
outImage | AvlNet.Image | Output image. |
Description
The operation replaces each pixel with the darkest pixel in its neighbourhood, thus shrinking bright areas in inImage and expanding the dark ones.
Examples
Hardware Acceleration
This operation is optimized for SSE2 technology for pixels of types: all formats (when inSourceRoi = NIL and inBorderColor = NIL).
This operation supports automatic parallelization for multicore and multiprocessor systems.
Hardware acceleration settings may be manipulated with Settings class.
Errors
Error type | Description |
---|---|
DomainError | inBorderColor is relevant only when inSourceRoi is set to Auto (NIL) in ErodeImage. |
DomainError | Not supported kernel on input in ErodeImage. |
