Figure 5
Sketches showing region growth around the indexed seeding voxel (coloured black and numbered 0). (a) The voxels grow successively, with one neighbouring voxel checked each time. The numbers represent a probable order of growth. (b) All the voxels within a bounding box are tested. The ones fulfilling the criterion are allowed to grow (marked yellow), whereas the rest are rejected for growth (marked red). |
