Basic| Module: | FoundationLite |
|---|
Replaces each pixel with the minimum of pixels within a small rectangular kernel.
| Name | Type | Description | |
|---|---|---|---|
 |
inImage | Image | Input image |
|
inRoi | Region* | Range of outImage pixels to be computed |
|
inKernel | MorphologyKernel | Selects a predefined kernel |
 |
outImage | 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.
This filter is a simplified version of ErodeImage. It is limited to only a few symmetric kernels and supports only basic ROI handling.
Please note that on some machines the filter execution time can be greater than execution time of the corresponding ErodeImage filter.
Examples

 |
ErodeImage_Mask performed on the sample image with inKernel = Box3x3.
Hardware Acceleration
This operation is optimized for SSE2 technology for pixels of types: UINT8, SINT16, UINT16.
This operation is optimized for AVX2 technology for pixels of types: UINT8, SINT16, UINT16.
This operation supports automatic parallelization for multicore and multiprocessor systems.
Errors
This filter can throw an exception to report error. Read how to deal with errors in Error Handling.
List of possible exceptions:
| Error type | Description |
|---|---|
| DomainError | Region exceeds an input image in ErodeImage_Mask. |
Complexity Level
This filter is available on Basic Complexity Level.
Filter Group
This filter is member of ErodeImage filter group.
