Region-Based PDEs for Cells Counting and Segmentation in 3D+Time Images of Vertebrate Early Embryogenesis
Figure 3
Graphical representation of the calibration of . Noisy spheres of different radii (1, 3, 5, and 7 voxels) segmented using different values of scale parameter. Figures (c) and (d) show the noisy data in a cutting plane and the segmentation (blue) in surface rendering. (a) Original spheres. (b) Noisy spheres (Gaussian noise with mean value 0 and standard deviation 50). (c) Segmentation with . (d) Segmentation with . Steady state after 1000 iterations for , otherwise 7000 (a) and 9000 (b) iterations.
