template<typename TScalar, unsigned int TImageDimension>
class itk::watershed::Relabeler< TScalar, TImageDimension >
This filter implements the final step in the watershed segmentation algorithm. It is responsible for relabeling a segmented image according to a specified saliency level (flood level) in a merge tree. (See itk::WatershedImageFilter for information on terminology used in this documentation.)
- Inputs
- There are two inputs to this filter. The first input is a labeled image of unsigned long integers, such as is produced by itk::watershed::Segmenter. The second input is an itk::watershed::SegmentTree, which is the merge tree data structure produced by the itk::watershed::SegmentTreeGenerator filter. The merge tree represents the hierarchy of merges among adjacent segments in the initial segmentation image.
- Output
- The output of this filter is a relabeled image of unsigned long integers of dimension and size matching the input.
- Parameters
- There is a single parameter FloodLevel for this filter. FloodLevel is given in percentage points (0.0 - 1.0) of the maximum saliency found in the merge tree. A FloodLevel of 0.0 will produce an output in which no segments are relabeled (merged). A FloodLevel of 1.0 will produce an output in which all the entries in the merge tree are used to relabel the image. FloodLevel controls which level in the segmentation hierarchy to produce on the output.

template<typename TScalar, unsigned int TImageDimension>
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).
Reimplemented from itk::ProcessObject.
template<typename TScalar, unsigned int TImageDimension>
Given one output whose requested region has been set, how should the requested regions for the remaining outputs of the process object be set? By default, all the outputs are set to the same requested region. If a filter needs to produce different requested regions for each output, for instance an image processing filter producing several outputs at different resolutions, then that filter may override this method and set the requested regions appropriately.
Note that a filter producing multiple outputs of different types is required to override this method. The default implementation can only correctly handle multiple outputs of the same type.
Reimplemented from itk::ProcessObject.
