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.

	)

Inserts a segment into the table

template<typename TScalar >

Iterator itk::watershed::SegmentTable< TScalar >::Begin ( void )

inline
