Detailed Description

template<typename TInputImage, typename TOutputImage = TInputImage, typename TWeights = float>
class itk::MultiLabelSTAPLEImageFilter< TInputImage, TOutputImage, TWeights >

This filter performs a pixelwise combination of an arbitrary number of input images, where each of them represents a segmentation of the same scene (i.e., image).

The labelings in the images are weighted relative to each other based on their "performance" as estimated by an expectation-maximization algorithm. In the process, a ground truth segmentation is estimated, and the estimated performances of the individual segmentations are relative to this estimated ground truth.

The algorithm is based on the binary STAPLE algorithm by Warfield et al. as published originally in [137].

The multi-label algorithm implemented here is described in detail in [93].

INPUTS: All input volumes to this filter must be segmentations of an image, that is, they must have discrete pixel values where each value represents a different segmented object.

Input volumes must all contain the same size RequestedRegions. Not all input images must contain all possible labels, but all label values must have the same meaning in all images.

The filter can optionally be provided with estimates for the a priori class probabilities through the SetPriorProbabilities function. If no estimate is provided, one is automatically generated by analyzing the relative frequencies of the labels in the input images.

OUTPUTS: The filter produces a single output volume. Each output pixel contains the label that has the highest probability of being the correct label, based on the performance models of the individual segmentations. If the maximum probability is not unique, i.e., if more than one label have a maximum probability, then an "undecided" label is assigned to that output pixel.

By default, the label used for undecided pixels is the maximum label value used in the input images plus one. Since it is possible for an image with 8 bit pixel values to use all 256 possible label values, it is permissible to combine 8 bit (i.e., byte) images into a 16 bit (i.e., short) output image.

In addition to the combined image, the estimated confusion matrices for each of the input segmentations can be obtained through the GetConfusionMatrix member function.

PARAMETERS: The label used for "undecided" labels can be set using SetLabelForUndecidedPixels. This functionality can be unset by calling UnsetLabelForUndecidedPixels.

A termination threshold for the EM iteration can be defined by calling SetTerminationUpdateThreshold. The iteration terminates once no single parameter of any confusion matrix changes by less than this threshold. Alternatively, a maximum number of iterations can be specified by calling SetMaximumNumberOfIterations. The algorithm may still terminate after a smaller number of iterations if the termination threshold criterion is satisfied.

EVENTS: This filter invokes IterationEvent() at each iteration of the E-M algorithm. Setting the AbortGenerateData() flag will cause the algorithm to halt after the current iteration and produce results just as if it had converged. The algorithm makes no attempt to report its progress since the number of iterations needed cannot be known in advance.

template<typename TInputImage, typename TOutputImage = TInputImage, typename TWeights = float>

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.

template<typename TInputImage, typename TOutputImage = TInputImage, typename TWeights = float>

void itk::MultiLabelSTAPLEImageFilter< TInputImage, TOutputImage, TWeights >::EnlargeOutputRequestedRegion ( DataObject * output )

overrideprotectedvirtual

Give the process object a chance to indicate 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.

◆ GenerateData()

void itk::MultiLabelSTAPLEImageFilter< TInputImage, TOutputImage, TWeights >::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.

See also: ThreadedGenerateData()

Reimplemented from itk::ImageSource< TInputImage >.

◆ GenerateInputRequestedRegion()

template<typename TInputImage, typename TOutputImage = TInputImage, typename TWeights = float>

void itk::MultiLabelSTAPLEImageFilter< TInputImage, TOutputImage, TWeights >::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 bool itk::MultiLabelSTAPLEImageFilter< TInputImage, TOutputImage, TWeights >::GetHasLabelForUndecidedPixels ( )

virtual

True if LabelForUndecidedPixels has been manually set.

◆ GetHasMaximumNumberOfIterations()

template<typename TInputImage, typename TOutputImage = TInputImage, typename TWeights = float>

virtual bool itk::MultiLabelSTAPLEImageFilter< TInputImage, TOutputImage, TWeights >::GetHasMaximumNumberOfIterations ( ) const

◆ GetHasPriorProbabilities()

template<typename TInputImage, typename TOutputImage = TInputImage, typename TWeights = float>

virtual bool itk::MultiLabelSTAPLEImageFilter< TInputImage, TOutputImage, TWeights >::GetHasPriorProbabilities ( )

template<typename TInputImage, typename TOutputImage = TInputImage, typename TWeights = float>

virtual OutputPixelType itk::MultiLabelSTAPLEImageFilter< TInputImage, TOutputImage, TWeights >::GetLabelForUndecidedPixels ( )

virtual

Get label value used for undecided pixels.

After updating the filter, this function returns the actual label value used for undecided pixels in the current output. Note that this value is overwritten when SetLabelForUndecidedPixels is called and the new value only becomes effective upon the next filter update.

◆ GetMaximumNumberOfIterations()

template<typename TInputImage, typename TOutputImage = TInputImage, typename TWeights = float>

virtual unsigned int itk::MultiLabelSTAPLEImageFilter< TInputImage, TOutputImage, TWeights >::GetMaximumNumberOfIterations ( ) const

virtual const PriorProbabilitiesType & itk::MultiLabelSTAPLEImageFilter< TInputImage, TOutputImage, TWeights >::GetPriorProbabilities ( ) const

virtual

Get prior class probabilities.

After updating the filter, this function returns the actual prior class probabilities. If these were not previously set by a call to SetPriorProbabilities, then they are estimated from the input segmentations and the result is available through this function.
