CloseImage


Module: FoundationLite

Removes small dark structures from an image (or fills in bright ones) by applying consecutive dilation and erosion.

Applications

E.g. removal of the "pepper" component of salt-and-pepper noise.
Name Type Range Description
Input value inImage Image Input image
Input value inRoi Region* Range of outImage pixels to be computed
Input value inSourceRoi Region* Range of inImage pixels to be considered in computations
Input value inBorderColor Pixel* Color of the imaginary pixels outside the image boundaries
Input value inKernel KernelShape Selects kernel shape
Input value inRadiusX Integer 0 - Nearly half of the kernel's width (2*R+1)
Input value inRadiusY Integer* 0 - Nearly half of the kernel's height
Output value outImage Image Output image
Diagnostic input diagKernel Region Kernel shape

Examples

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

CloseImage used to remove dark scratches from an image.

Hardware Acceleration

This operation is optimized for SSE2 technology for pixels of types: all formats (when inSourceRoi = NIL and inBorderColor = NIL).

This operation is optimized for NEON 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 CloseImage.
