Detailed Description

Helper class for post-processing a label map.

Public Types
enum class	SmoothingMode { Gaussian = 0 , Median }
	Types of smoothing.

Public Member Functions
	LabelMapRefinement (const SharedImageSet *image, SharedImageSet &labelMap)
	If image is provided, it is expected that image and labelMap contain the same number of images, and that each of the images are compatible with one-another.

void	setMask (ExplicitMask *mask)
	Set a mask to prevent certain values from being modified by the refinement For performance reasons, only ExplicitMask (of compatible dimensions) are supported.

void	setAffectedLabel (uint8_t label)
	Set which of the label will be affected by the refinement operations 0 by default.

bool	setAffectedFrames (int firstFrame, int lastFrame)
	Select the range of frame on which the operation is performed.

void	lockLabel (uint8_t label, bool locked)
	Determines which labels are locked.

void	removeSmallComponents (std::optional< int > maxNumComponents, std::optional< size_t > minComponentSizeInPixels)
	Remove the small components from the label map.

void	keepNLargestComponents (int n)
	Keep only the n largest components of the label maps.

void	fillHoles ()
	Fill any holes in the label map.

void	smooth (int kernelSize, SmoothingMode mode)
	Smooths the current label values in the label map.

void	imageBasedRefinement (int kernelSize)
	Applies a smoothing to the label map that takes into account the image intensities This operation requires that the 'image' was passed in the constructor.

void	dilate (int kernelSize)
	Dilates the current label values in the label map.

void	erode (int kernelSize)
	Erodes the current label values in the label map.

Constructor & Destructor Documentation

◆ LabelMapRefinement()

LabelMapRefinement	(	const SharedImageSet *	image,
		SharedImageSet &	labelMap )

If image is provided, it is expected that image and labelMap contain the same number of images, and that each of the images are compatible with one-another.

Parameters

image	is optional. Some operations (documented below) require it
labelMap	the labelMap on which the transformations will be applied. Must be of type 'uint8_t'

Member Function Documentation

◆ setAffectedFrames()

bool setAffectedFrames	(	int	firstFrame,
		int	lastFrame )

Select the range of frame on which the operation is performed.

All frames between firstFrame (inclusive) and lastFrame (exclusive) will be affected. If firstFrame is -1 (the default), lastFrame is ignored and only the focus frame of the labelMap will be affected. Returns true if the frame selection is valid, false otherwise

◆ lockLabel()

void lockLabel	(	uint8_t	label,
		bool	locked )

Determines which labels are locked.

'true' means that a label is locked, and 'false' that it is not Operations will not modify any pixel value that has been locked No labels are locked by default

◆ removeSmallComponents()

void removeSmallComponents	(	std::optional< int >	maxNumComponents,
		std::optional< size_t >	minComponentSizeInPixels )

Remove the small components from the label map.

If maxNumComponents is specified, the components that are not part of the maxNumComponents largest ones will be removed. If minComponentSize is specified, the components smaller than this threshold (in pixels) will be removed.
