Detailed Description

template<typename TScalar>
class itk::watershed::SegmentTable< TScalar >

A table for storing segmentation information in various component filters of the watershed segmentation algorithm. See itk::WatershedImageFilter for an overview.

: This is a hash table that holds information about labeled segments in an image. Keys in the table are label values (IdentifierType). Each entry in the table records the minimum value in the segment region and a list of all the adjacent segments in the image. The adjacency (edge) list also holds a saliency value (likelihood of merge) for each adjacency.

template<typename TScalar >

ConstIterator itk::watershed::SegmentTable< TScalar >::Begin ( ) const

void itk::watershed::SegmentTable< TScalar >::PruneEdgeLists ( ScalarType maximum_saliency )

Iterates through the table and removes edges in every edge list whose saliencies are above the specified maximum. Requires that the edge lists have been sorted prior to calling this method.

template<typename TScalar >

void itk::watershed::SegmentTable< TScalar >::SetMaximumDepth ( ScalarType s )

Set/Get the maximum depth of image on which this segment table is based. (Should set really be calling modified? jc 11/16/01)
