OpenImage


Header: AVL.h
Namespace: avl
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.

Syntax

C++
C#
 
void avl::OpenImage
(
	const avl::Image& inImage,
	atl::Optional<const avl::Region&> inRoi,
	atl::Optional<const avl::Region&> inSourceRoi,
	atl::Optional<avl::Pixel> inBorderColor,
	avl::KernelShape::Type inKernel,
	int inRadiusX,
	atl::Optional<int> inRadiusY,
	avl::Image& outImage,
	avl::Region& diagKernel
)

Parameters

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

In-place Processing

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

Examples

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.
