#include <itkLabelVotingImageFilter.h>

Detailed Description

template<typename TInputImage, typename TOutputImage = TInputImage>
class itk::LabelVotingImageFilter< TInputImage, TOutputImage >

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

Label voting is a simple method of classifier combination applied to image segmentation. Typically, the accuracy of the combined segmentation exceeds the accuracy of any of the input segmentations. Voting is therefore commonly used as a way of boosting segmentation performance.

The use of label voting for combination of multiple segmentations is described in [100].

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.

OUTPUTS
The voting filter produces a single output volume. Each output pixel contains the label that occurred most often among the labels assigned to this pixel in all the input volumes, that is, the label that received the maximum number of "votes" from the input pixels.. If the maximum number of votes is not unique, i.e., if more than one label have a maximum number of votes, 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.

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

◆ BeforeThreadedGenerateData()

template<typename TInputImage, typename TOutputImage = TInputImage>
void itk::LabelVotingImageFilter< TInputImage, TOutputImage >::BeforeThreadedGenerateData ( )

Determine maximum label value in all input images and initialize global data.

Reimplemented from itk::ImageSource< TInputImage >.

◆ ComputeMaximumInputValue()

◆ CreateAnother()

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::LightObject.

◆ DynamicThreadedGenerateData()

template<typename TInputImage, typename TOutputImage = TInputImage>
void itk::LabelVotingImageFilter< TInputImage, TOutputImage >::DynamicThreadedGenerateData ( const OutputImageRegionType & outputRegionForThread)
overrideprotectedvirtual

If an imaging filter can be implemented as a multithreaded algorithm, the filter will provide an implementation of ThreadedGenerateData() or DynamicThreadedGenerateData(). This superclass will automatically split the output image into a number of pieces, spawn multiple threads, and call (Dynamic)ThreadedGenerateData() in each thread. Prior to spawning threads, the BeforeThreadedGenerateData() method is called. After all the threads have completed, the AfterThreadedGenerateData() method is called. If an image processing filter cannot support threading, that filter should provide an implementation of the GenerateData() method instead of providing an implementation of (Dynamic)ThreadedGenerateData(). If a filter provides a GenerateData() method as its implementation, then the filter is responsible for allocating the output data. If a filter provides a (Dynamic)ThreadedGenerateData() method as its implementation, then the output memory will allocated automatically by this superclass. The (Dynamic)ThreadedGenerateData() method should only produce the output specified by "outputThreadRegion" parameter. (Dynamic)ThreadedGenerateData() cannot write to any other portion of the output image (as this is responsibility of a different thread).

DynamicThreadedGenerateData() is the newer variant without threadId, and is the preferred signature, which is called by default. This variant can split the requested region into different number of pieces depending on current multi-processing load, which allows better load balancing. The non-dynamic (also known as classic) ThreadedGenerateData() signature has threadId, and number of pieces to be split into is known in advance. It is activated by calling this->DynamicMultiThreadingOff(); in derived class constructor. It should be used when the multi-threaded algorithm needs to pre-allocate some data structure with size dependent on the number of pieces (also known as chunks, work units, and sometimes also incorrectly as threads). Only PlatformMultiThreader guarantees that each piece will be processed in its own specific thread. Pool and TBB multi-threaders maintain a pool of threads (normally equal to number of processing cores) which they use to process the pieces. This normally results in a single thread being reused to process multiple work units.

◆ GetLabelForUndecidedPixels()

template<typename TInputImage, typename TOutputImage = TInputImage>
OutputPixelType itk::LabelVotingImageFilter< TInputImage, TOutputImage >::GetLabelForUndecidedPixels ( ) const
inline

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.
