Detailed Description

template<typename TInputImage, typename TOutputImage>
class itk::IsolatedConnectedImageFilter< TInputImage, TOutputImage >

Label pixels that are connected to one set of seeds but not another.

IsolatedConnectedImageFilter finds the optimal threshold to separate two regions. It has two modes, one to separate dark regions surrounded by bright regions by automatically finding a minimum isolating upper threshold, and another to separate bright regions surrounded by dark regions by automatically finding a maximum lower isolating threshold. The mode can be chosen by setting FindUpperThresholdOn()/Off(). In both cases, the isolating threshold is retrieved with GetIsolatedValue().

The algorithm labels pixels with ReplaceValue that are connected to Seeds1 AND NOT connected to Seeds2. When finding the threshold to separate two dark regions surrounded by bright regions, given a fixed lower threshold, the filter adjusts the upper threshold until the two sets of seeds are not connected. The algorithm uses a binary search to adjust the upper threshold, starting at Upper. The reverse is true for finding the threshold to separate two bright regions. Lower defaults to the smallest possible value for the InputImagePixelType, and Upper defaults to the largest possible value for the InputImagePixelType.

The user can also supply the Lower and Upper values to restrict the search. However, if the range is too restrictive, it could happen that no isolating threshold can be found between the user specified Lower and Upper values. Therefore, unless the user is sure of the bounds to set, it is recommended that the user set these values to the lowest and highest intensity values in the image, respectively.

The user can specify more than one seed for both regions to separate. The algorithm will try find the threshold that ensures that all of the first seeds are contained in the resulting segmentation and all of the second seeds are not contained in the segmentation.

It is possible that the algorithm may not be able to find the isolating threshold because no such threshold exists. The user can check for this by querying the GetThresholdingFailed() flag.

virtual::itk::LightObject::Pointer itk::IsolatedConnectedImageFilter< TInputImage, TOutputImage >::CreateAnother ( ) const

virtual

Create an object from an instance, potentially deferring to a factory. This method allows you to create an instance of an object that is exactly the same type as the referring object. This is useful in cases where an object has been cast back to a base class.

Reimplemented from itk::Object.

void itk::IsolatedConnectedImageFilter< TInputImage, TOutputImage >::EnlargeOutputRequestedRegion ( DataObject *  )

overrideprotectedvirtual

Give the process object a chance to indictate that it will produce more output than it was requested to produce. For example, many imaging filters must compute the entire output at once or can only produce output in complete slices. Such filters cannot handle smaller requested regions. These filters must provide an implementation of this method, setting the output requested region to the size they will produce. By default, a process object does not modify the size of the output requested region.

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

overrideprotectedvirtual

A version of GenerateData() specific for image processing filters. This implementation will split the processing across multiple threads. The buffer is allocated by this method. Then the BeforeThreadedGenerateData() method is called (if provided). Then, a series of threads are spawned each calling DynamicThreadedGenerateData(). After all the threads have completed processing, the AfterThreadedGenerateData() method is called (if provided). If an image processing filter cannot be threaded, the filter should provide an implementation of GenerateData(). That implementation is responsible for allocating the output buffer. If a filter can be threaded, it should NOT provide a GenerateData() method but should provide a DynamicThreadedGenerateData() instead.

template<typename TInputImage , typename TOutputImage >

void itk::IsolatedConnectedImageFilter< TInputImage, TOutputImage >::GenerateInputRequestedRegion ( )

overrideprotectedvirtual

What is the input requested region that is required to produce the output requested region? The base assumption for image processing filters is that the input requested region can be set to match the output requested region. If a filter requires more input (for instance a filter that uses neighborhoods needs more input than output to avoid introducing artificial boundary conditions) or less input (for instance a magnify filter) will have to override this method. In doing so, it should call its superclass' implementation as its first step. Note that imaging filters operate differently than the classes to this point in the class hierarchy. Up till now, the base assumption has been that the largest possible region will be requested of the input.

This implementation of GenerateInputRequestedRegion() only processes the inputs that are a subclass of the ImageBase<InputImageDimension>. If an input is another type of DataObject (including an Image of a different dimension), they are skipped by this method. The subclasses of ImageToImageFilter are responsible for providing an implementation of GenerateInputRequestedRegion() when there are multiple inputs of different types.

virtual void itk::IsolatedConnectedImageFilter< TInputImage, TOutputImage >::SetFindUpperThreshold ( bool  _arg )

virtual

Set/Get whether to find an upper threshold (separating two dark regions) or a lower threshold (separating two bright regions).

template<typename TInputImage , typename TOutputImage >

virtual void itk::IsolatedConnectedImageFilter< TInputImage, TOutputImage >::SetIsolatedValueTolerance ( InputImagePixelType  _arg )

virtual

Set/Get the precision required for the intensity threshold value. The default is 1.

template<typename TInputImage , typename TOutputImage >

virtual void itk::IsolatedConnectedImageFilter< TInputImage, TOutputImage >::SetLower ( InputImagePixelType  _arg )

virtual

Set/Get the limit on the lower threshold value. The default is the NonpositiveMin() for the InputPixelType.

template<typename TInputImage , typename TOutputImage >

virtual void itk::IsolatedConnectedImageFilter< TInputImage, TOutputImage >::SetReplaceValue ( OutputImagePixelType  _arg )

virtual

Set/Get value to replace thresholded pixels. Pixels that lie within the thresholds will be replaced with this value. The default is 1.

template<typename TInputImage , typename TOutputImage >

void itk::IsolatedConnectedImageFilter< TInputImage, TOutputImage >::SetSeed1

(

const IndexType &

seed

)

Set a single seed point 1.

This seed will be isolated from Seed2 (if possible). All pixels connected to this seed will be replaced with ReplaceValue.

template<typename TInputImage , typename TOutputImage >

void itk::IsolatedConnectedImageFilter< TInputImage, TOutputImage >::SetSeed2

(

const IndexType &

seed

)

Set a single seed point 2.

This seed will be isolated from Seed1 (if possible).

template<typename TInputImage , typename TOutputImage >

virtual void itk::IsolatedConnectedImageFilter< TInputImage, TOutputImage >::SetUpper ( InputImagePixelType  _arg )

virtual

Set/Get the limit on the upper threshold value. The default is the max() for the InputPixelType.
