Member Function Documentation

template<class TInputImage>
void itk::watershed::Segmenter< TInputImage >::AnalyzeBoundaryFlow InputImageTypePointer   ,
flat_region_table_t  ,
InputPixelType   
[protected]
 

Performs a gradient descent connected component analysis at the boundaries of the images that border other image chunks. Useful only in data streaming applications.

template<class TInputImage>
void itk::watershed::Segmenter< TInputImage >::BuildRetainingWall InputImageTypePointer   ,
ImageRegionType   ,
InputPixelType   
[protected]
 

Fills boundary pixels with a specified value. Used by labeling methods to build a very high ``wall'' around the image so that gradient descent does not need to watch boundaries.

template<class TInputImage>
void itk::watershed::Segmenter< TInputImage >::CollectBoundaryInformation flat_region_table_t   [protected]
 

Traverses each boundary and fills in the data needed for joining streamed chunks of an image volume. Only necessary for streaming applications.

Reimplemented from itk::ProcessObject.

template<class TInputImage>
void itk::watershed::Segmenter< TInputImage >::GenerateOutputRequestedRegion DataObject   output [protected, virtual]
 

This method asks for an image region that is one pixel larger at each boundary than the region being processed. This single pixel expansion represents an overlap with adjacent image chunks

Reimplemented from itk::ProcessObject.

template<class TInputImage>
BoundaryType* itk::watershed::Segmenter< TInputImage >::GetBoundary void    [inline]
 

Returns the boundary information data necessary only for data streaming applications.

Definition at line 160 of file itkWatershedSegmenter.h.

template<class TInputImage>
virtual const char* itk::watershed::Segmenter< TInputImage >::GetClassName   const [virtual]
 

Methods to implement smart pointers and work with the itk object factory

Reimplemented from itk::ProcessObject.

template<class TInputImage>
virtual unsigned long itk::watershed::Segmenter< TInputImage >::GetCurrentLabel   [virtual]
 

Gets/Sets the initial label (unsigned long integer value) used by the labeling algorithm. Only necessary for streaming applications.

template<class TInputImage>
virtual bool itk::watershed::Segmenter< TInputImage >::GetDoBoundaryAnalysis   [virtual]
 

Turns on special labeling of the boundaries for streaming applications. The default value is FALSE, meaning that boundary analysis is turned off.

template<class TInputImage>
InputImageType* itk::watershed::Segmenter< TInputImage >::GetInputImage void    [inline]
 

Get/Set the input image.

Definition at line 133 of file itkWatershedSegmenter.h.

template<class TInputImage>
ImageRegionType itk::watershed::Segmenter< TInputImage >::GetLargestPossibleRegion   const [inline]
 

This method is necessary until the streaming mechanisms of the Itk pipeline are full fleshed out. It is only used for streaming applications. Calling this method gets/sets the image size of the complete volume being streamed. The member variables controlled by this method will not be modified by the Itk pipeline and are necessary for analysis of boundaries.

Definition at line 182 of file itkWatershedSegmenter.h.

template<class TInputImage>
virtual InputPixelType itk::watershed::Segmenter< TInputImage >::GetMaximum   [virtual]
 

Prior to thresholding the input image, the filter calculates minimum and maximum values for the image. These values are stored as member variables.

template<class TInputImage>
virtual InputPixelType itk::watershed::Segmenter< TInputImage >::GetMinimum   [virtual]

Definition at line 151 of file itkWatershedSegmenter.h.

template<class TInputImage>
virtual bool itk::watershed::Segmenter< TInputImage >::GetSortEdgeLists   [virtual]
 

Determines whether the algorithm will sort the adjacencies in its SegmentTable before returning. Default is true. This is an option only useful for streaming applications where the sorting only needs to be done after all iterations have taken place.

template<class TInputImage>
virtual double itk::watershed::Segmenter< TInputImage >::GetThreshold   [virtual]
 

Gets/Sets the input threshold. Threshold is specified as a percentage (0.0 - 1.0) of the maximum height of the image. This filter thresholds the input image to remove all values below /f$ L = min + T * (max - min) /f$, where /f$ max, min /f$ are the maximum, minimum values in the image and /f$ T /f$ is the threshold parameter value. Values in the image less than /f$ L /f$ are raised to /f$ L /f$. Thresholding minimum values in the image decreases the number of local minima in the image and produces an initial segmentation with fewer segments. The assumption is that the ``shallow'' regions that this thresholding eliminates are generally not of interest.

template<class TInputImage>
void itk::watershed::Segmenter< TInputImage >::GradientDescent InputImageTypePointer   ,
