Detailed Description

template<class TInputImage, class TOutputImage>
class itk::IntelligentBinaryClosingFilter< TInputImage, TOutputImage >

Performs a morphological closing on a binary image, selectively filling only those holes whose surface-to-volume ratio exceeds a given threshold.

Unlike a standard binary closing, this filter analyzes connected components in the closed region (the difference between dilated and eroded images) and only fills components that meet the surface ratio criterion. This prevents the closing operation from filling large cavities that should be preserved.

The filter internally uses a mini-pipeline consisting of dilation, erosion, subtraction, connected component analysis, and relabeling filters.

Template Parameters

TInputImage	The input image type (binary image).
TOutputImage	The output image type (typically a labeled or binary image).

◆ GenerateData()

template<class TInputImage , class TOutputImage >

void itk::IntelligentBinaryClosingFilter< TInputImage, TOutputImage >::GenerateData ( )

override

Execute the intelligent binary closing algorithm.

This method is not multithreaded. It runs the internal mini-pipeline (dilate, erode, subtract, connected component analysis) and selectively fills holes based on the surface ratio.

◆ GetClassName()

virtual const char* itk::IntelligentBinaryClosingFilter< TInputImage, TOutputImage >::GetClassName ( ) const

virtual

Run-time type information (and related methods)

◆ GetClosingRadius()

template<class TInputImage , class TOutputImage >

virtual float itk::IntelligentBinaryClosingFilter< TInputImage, TOutputImage >::GetClosingRadius ( )

virtual

Get the radius used for the morphological closing structuring element.

Returns: The closing radius in pixels.

◆ GetSurfaceRatio()

template<class TInputImage , class TOutputImage >

virtual float itk::IntelligentBinaryClosingFilter< TInputImage, TOutputImage >::GetSurfaceRatio ( )

virtual

Get the surface-to-volume ratio threshold.

Returns: The surface ratio threshold.

◆ itkStaticConstMacro()

template<class TInputImage , class TOutputImage >

itk::IntelligentBinaryClosingFilter< TInputImage, TOutputImage >::itkStaticConstMacro	(	ImageDimension	,
		unsigned int	,
		TInputImage::ImageDimension
	)

Dimension of the input and output images.

◆ New()

template<class TInputImage , class TOutputImage >

void itk::IntelligentBinaryClosingFilter< TInputImage, TOutputImage >::SetInput ( const InputImageType * input )

inlineoverride

Set the input binary image.

Overloaded to also connect the input to the internal dilation filter.

Parameters

[in] input The input binary image.

Definition at line 93 of file itkIntelligentBinaryClosingFilter.h.

◆ SetInput() [2/2]

template<class TInputImage , class TOutputImage >

void itk::IntelligentBinaryClosingFilter< TInputImage, TOutputImage >::SetInput	(	unsigned int	i,
		const TInputImage *	image
	)
