Detailed Description

template<class TPixelType, unsigned int TDimension>
class itk::watershed::BoundaryResolver< TPixelType, TDimension >

This filter implements a piece of the streaming watershed segmentation algorithm. It takes in pairs of itk::watershed::Boundary objects and connects the labeling of pixels across image chunk boundaries. Read the documentation found in itk::WatershedImageFilter and the other watershed segmentation component objects for more information.

A note on terminology in itk watershed segmentation code

For streamed segmentation of images in the watershed framework, the documentation refers to the complete data set at the ``image volume.'' The image volume is assumed to be partitioned into pieces referred to as image chunks. Each chunk is processed in sequence through the pipeline. The ``face'' of an image chunk is an N-1 dimensional boundary region of an N dimensional chunk (the planar faces of a cube, for example).

Input

The input to this filter is a pair of itk::watershed::Boundary pointers (BoundaryA and BoundaryB). The algorithm assumes that these Boundaries come from facing chunks in the image volume. The faces that align need to be specified in the parameters of the filter.

Output

This filter outputs a table of equivalencies among labels. See itk::EquivalencyTable for more information.

Parameters

The only parameters to set on this filter are the indicies of the faces that align in the boundary object inputs. See itk::Boundary for a description of how boundary faces are indexed.

Member Function Documentation

template<class TPixelType, unsigned int TDimension> void itk::watershed::BoundaryResolver< TPixelType, TDimension >::GenerateData (   )  [virtual]

Standard non-threaded pipeline method Reimplemented from itk::ProcessObject.

template<class TPixelType, unsigned int TDimension> void itk::watershed::BoundaryResolver< TPixelType, TDimension >::GenerateOutputRequestedRegion (  DataObject *  output  )  [protected, virtual]

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 appropriatedly. 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.
