Region-Based PDEs for Cells Counting and Segmentation in 3D+Time Images of Vertebrate Early Embryogenesis

Figure 5

A region of interest selected on real data, gold standard obtained by manual segmentation, and surfaces segmented using (4) and (5). In every case . Steady state is, respectively, after 1300 and 1500 iterations. (a) Isosurface of original data. (b) Gold standard. (c) Segmentation with . (d) Segmentation with superimposed to gold standard (red, transparent). (c) Segmentation with . (d) Segmentation with superimposed to gold standard (red, transparent). Using is not possible to segment all the nuclei in the region.
