Module: | FoundationLite |
---|
Removes small bright structures from an image (or fills in dark ones) by applying consecutive erosion and dilation.
Applications
E.g. removal of the "salt" component of salt-and-pepper noise.

Nearly half of the kernel's width (2*R+1) |
![]() |
inRadiusY | Integer* | 0 - ![]() |
Nearly half of the kernel's height (2*R+1), or same as inRadiusX |
![]() |

Examples
Description of usage of this filter can be found in examples and tutorial: Pattern Cutting.

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.
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 OpenImage. |
Complexity Level
This filter is available on Basic Complexity Level.
