Detailed Description

template<typename DATATYPE>
class ml::SimilarIntensitiesClusterAlgorithm< DATATYPE >

Implementation of a SimilarIntensities clustering algorithm.

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 it belongs to the background or if not, if it has neighbors with a similar gray value. Merging adjacent cluster is done within ClusterRefCollection.
