DilateAndErodeImage

Header:	FIL.h
Namespace:	fil

Calculates dilation and erosion simultaneously for faster execution.

Syntax

void fil::DilateAndErodeImage
(
	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& outDilated,
	fil::Image& outEroded
)

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 read
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
outDilated	Image&
outEroded	Image&

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

List of possible exceptions:

Error type	Description
DomainError	inBorderColor is relevant only when inSourceRoi is set to Auto (NIL) in DilateAndErodeImage.
DomainError	Not supported kernel on input in DilateAndErodeImage.
