Detailed Description

template<class TScalarType>
class itk::watershed::SegmentTreeGenerator< TScalarType >

This filter is a process object class that implements a step in the N-d watershed segmentation algorithm. It produces an ordered list (SegmentTree) of binary merges between segments at increasing saliency levels. This filter is used in conjunction with WatershedSegmenter and WatershedRelabeler to process an initial segmentation into a final relabeled volume. See itk::WatershedImageFilter for an overview of watershed segmentation.

Inputs
There are two inputs to this filter, the second is optional. (1) A table of segments (SegmentTable) derived from a labeled image. (2) Optionally, a table of predetermined equivalencies among segments (EquivalencyTable), necessary for streaming applications where segments may be joined across streamed chunk boundaries. The flag Merge must be set to true to enable this functionality.
Outputs
The output of this filter is a list of binary merges of segments at increasing saliency. This is the data structure itk::watershed::WatershedSegmentTree referred to as a ``merge tree'' in the itk::WatershedImageFilter documentation.
Parameters
There are two parameters to this filter described below.
FloodLevel is specified as a percentage (0.0 - 1.0) of the maximum possible saliency value in the initial image from which the segment table was derived. A value of 0.0 calculates no merges. A value of 1.0 calculates all of the potential merges that can occur as the FloodLevel is increased to the maximum saliency value. Typically, there is no need to calculate merges past about 40% of the total depth. Because this is the most computationally intensive piece of the watershed segmentation algorithm, it is a good idea to tune this parameter as low as possible on larger volumes.
Merge is a boolean flag indicating whether or not to pre-merge the segments marked as equivalent in the EquivalencyTable. This is only useful for streaming applications and is turned off by default. (TRUE == merge, FALSE == do not merge).

template<class TScalarType>
void itk::watershed::SegmentTreeGenerator< TScalarType >::GenerateInputRequestedRegion ( )
protectedvirtual

What is the input requested region that is required to produce the output requested region? By default, the largest possible region is always required but this is overridden in many subclasses. For instance, for an image processing filter where an output pixel is a simple function of an input pixel, the input requested region will be set to the output requested region. For an image processing filter where an output pixel is a function of the pixels in a neighborhood of an input pixel, then the input requested region will need to be larger than the output requested region (to avoid introducing artificial boundary conditions). This function should never request an input region that is outside the the input largest possible region (i.e. implementations of this method should crop the input requested region at the boundaries of the input largest possible region).

template<class TScalarType>
virtual DataObjectPointer itk::watershed::SegmentTreeGenerator< TScalarType >::MakeOutput ( DataObjectPointerArraySizeType  idx)
virtual

Make a DataObject of the correct type to used as the specified output. Every ProcessObject subclass must be able to create a DataObject that can be used as a specified output. This method is automatically called when DataObject::DisconnectPipeline() is called. DataObject::DisconnectPipeline, disconnects a data object from being an output of its current source. When the data object is disconnected, the ProcessObject needs to construct a replacement output data object so that the ProcessObject is in a valid state. So DataObject::DisconnectPipeline eventually calls ProcessObject::MakeOutput. Note that MakeOutput always returns a itkSmartPointer to a DataObject. ImageSource and MeshSource override this method to create the correct type of image and mesh respectively. If a filter has multiple outputs of different types, then that filter must provide an implementation of MakeOutput().
