3D Segmentierung mittels hierarchischer Inselstrukturen

Analysis of brain images using the 3D-CSC segmentation method

“…Therefor, a generalization to 3D images was done in a common project of the Research Center Jülich and the University Koblenz-Landau, see, e.g. [ 7 ]. The first step is to find a 3D analogon of the hierarchical hexagonal island structure.…”

“…The 3-D-GSC [16] merges local precision and global view by re-evaluating homogeneity decisions taken on a lower hierarchy level on the basis of the global view through a subsequent splitting of contiguous but non-similar regions. The GSC algorithmworks on a newly developed 3-D island structure havingthe properties introduced in the following due to the requirements indicated:…”

“…In [16] it has been proven that only the 14-neighborship of a rhombic dodecahedron (see Fig. 1) can satisfy the aforementioned requirements, but not all overlapping points in a macro island can be examined during linking due to the inhomogeneous neighborhood structure.…”

“…Vogelbruch [16]- [18] extended this algorithm to 3-D(3-D-GSC) by identification of an appropriate 3-D island structure and proving this to be unique in 3-D. These approaches both are implicitly parallel because the island itself and islands of each hierarchy level can be processed independently.…”

“…The S 15 structure (see figure 1b), as used in [3], builds up a cell hierarchy that covers nearly all properties of the hexagonal island hierarchy. Unfortunately, the S 15 cell hierarchy does not fulfill the important density property, i.e.…”
