Detailed Description

Implementation of a clustering algorithm for vector data types.

It uses internally two data structures. One (class ClusterRefVolume) holds references for every image voxel to a field of cluster informations (here ClusterRefCollection). For every image voxel will be checked whether the difference between the directions of neighboring vectors is within a similarity tolerance. Merging adjacent cluster is done within ClusterRefCollection.
