Detailed Description

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

A data structure for storing segment merge information used in filters of the watershed segmentation algorithm. See itk::WatershedImageFilter for an overview.

This class is the implementation of the "merge tree" referred to in the documentation for itk::WatershedImageFilter and other watershed segmentation component classes. It holds a list of merges among image segments at various saliency levels. The list is actually a representation of a binary tree, whose nodes are segments and edges are saliencies.
