Geometric features of cell/compartments pairs. (A) Trans-PMT image of stage III spheroid in top view, with elliptical outline (white), estimated PA axis (yellow) that is orthogonal to line through gonidia (green dots). Overlaid are segmentations of CZ3 compartments, colored dark to light by size. (B–G) Schematics of geometric features computed from cell (green) and compartment (yellow) boundaries, as indicated: (B) $a_{\mathrm{cell}},a_{\mathrm{cz}3}$, (C) aspect ratio $\alpha$ and corresponding ellipse (cyan) with major and minor axes in blue and red, (D) deviation from a circle of the same area (cyan), (E) offset of cell area center of mass (green star) from compartment area center of mass (yellow star), (F) whitening transform of the compartment area (cyan), and (G) Voronoi tessellation (white) error $e_V$.
