FIL.OpenImage

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

Namespace:FilNet
Assembly:FIL.NET.dll

Syntax

C++
C#
 
public static void OpenImage
(
	FilNet.Image inImage,
	NullableRef<FilNet.Region> inRoi,
	NullableRef<FilNet.Region> inSourceRoi,
	FilNet.Pixel? inBorderColor,
	FilNet.KernelShape inKernel,
	int inRadiusX,
	int? inRadiusY,
	FilNet.Image outImage,
	FilNet.Region diagKernel
)

Parameters

Name Type Range Default Description
inImageFilNet.ImageInput image.
inRoiFilNet.NullableRef<FilNet.Region>Range of outImage pixels to be computed. Default value: ftl::NIL.
inSourceRoiFilNet.NullableRef<FilNet.Region>Range of inImage pixels to be considered in computations. Default value: ftl::NIL.
inBorderColorFilNet.Pixel?Color of the imaginary pixels outside the image boundaries. Default value: ftl::NIL.
inKernelFilNet.KernelShapeKernel shape.
inRadiusXint<0, INF>1Nearly half of the kernel's width (2*R+1). Default value: 1.
inRadiusYint?<0, INF>Nearly half of the kernel's height (2*R+1), or same as inRadiusX. Default value: ftl::NIL.
outImageFilNet.ImageOutput image.
diagKernelFilNet.RegionKernel shape.

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.

Hardware acceleration settings may be manipulated with Settings class.

Errors
