CloseImage

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

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

E.g. removal of the "pepper" component of salt-and-pepper noise.

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

CloseImage used to remove dark scratches from an image.

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.

This filter is available on Basic Complexity Level.
