mitk::UnstructuredGridClusteringFilter Class Reference

This filter uses the DBSCAN algorithm for clustering an mitk::UnstructuredGrid. "MinPts" defines the number of neighbours which are required to be a kernel point if a point is in range of a kernel point but hasnt enough neighbours this point is added to the cluster but is a density reachable point and the cluster ends at this point. "eps" is the range in which the neighbours are searched. If "Meshing" is set the clusteres UnstructuredGrid is meshed and visible in 2D renderwindows. More...

Detailed Description

This filter uses the DBSCAN algorithm for clustering an mitk::UnstructuredGrid. "MinPts" defines the number of neighbours which are required to be a kernel point if a point is in range of a kernel point but hasnt enough neighbours this point is added to the cluster but is a density reachable point and the cluster ends at this point. "eps" is the range in which the neighbours are searched. If "Meshing" is set the clusteres UnstructuredGrid is meshed and visible in 2D renderwindows.

DBSCAN algorithm:

DBSCAN(D, eps, MinPts)
C = 0
for each unvisited point P in dataset D
  mark P as visited
  N = D.regionQuery(P, eps)
  if sizeof(N) < MinPts
    mark P as NOISE
  else
    C = next cluster
    expandCluster(P, N, C, eps, MinPts)

expandCluster(P, N, C, eps, MinPts)
  add P to cluster C
  for each point P' in N
    if P' is not visited
      mark P' as visited
      N' = D.regionQuery(P', eps)
      if sizeof(N') >= MinPts
        N = N joined with N'
    if P' is not yet member of any cluster
      add P' to cluster C
