Figure 2
A schematic diagram illustrating the guidance of Dmedian for choosing the orientation between two candidates for accepting a voxel into a grown region. Both orientations give the same completeness (C = 2/5 = 0.4), whereas Dmedian is smaller for orientation 1 than for orientation 2. Therefore, orientation 1 is assigned to this voxel as long as the completeness value fulfils the growth criterion. |
