General qualitative similarity between randomly drawn samples of (a) synthetically generated DIC cell images using the proposed simulator, and (b) actual DIC microscopy images of rodent neurons. Similarities in imagery characteristics include: (1) DIC optical features as shown by the 3D relief which are highlighted by the high/low intensity ‘shadows’ in the cell edges, (2) organic interference which appears as Gaussian noise with a frequency profile (further elaboration on quantitative similarities are found in Appendix A-C2), (3) cell shapes as demonstrated by the cell shapes’ organic and natural contours, and (4) uneven lighting bias as shown by the smooth but uneven background gradient.
