OpenImage

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.

Syntax

void fil::OpenImage
(
	const fil::Image& inImage,
	ftl::Optional<const fil::Region&> inRoi,
	ftl::Optional<const fil::Region&> inSourceRoi,
	ftl::Optional<fil::Pixel> inBorderColor,
	fil::KernelShape::Type inKernel,
	int inRadiusX,
	ftl::Optional<int> inRadiusY,
	fil::Image& outImage,
	fil::Region& diagKernel
)

Parameters

	Name	Type	Range	Default	Description
	inImage	const Image&			Input image
	inRoi	Optional<const Region&>		NIL	Range of outImage pixels to be computed
	inSourceRoi	Optional<const Region&>		NIL	Range of inImage pixels to be considered in computations
	inBorderColor	Optional<Pixel>		NIL	Color of the imaginary pixels outside the image boundaries
	inKernel	KernelShape::Type			Kernel shape
	inRadiusX	int	0 -	1	Nearly half of the kernel's width (2*R+1)
	inRadiusY	Optional<int>	0 -	NIL	Nearly half of the kernel's height (2*R+1), or same as inRadiusX
	outImage	Image&			Output image
	diagKernel	Region&			Kernel shape

In-place Processing

This function supports in-place data processing - you can pass the same reference to inImage and outImage
