Segmentations at depth $d$: epidermis (red), uncertain (yellow), dermis (blue). (a) Annotated image at depth $d$, (b) RF at depth $d$, (c) ${\mathrm{CRF}}_{2\text{-}\mathrm{D}}$ at depth $d$, (d) ${\mathrm{CRF}}_{3\text{-}\mathrm{D}\mathrm{Sym}}$ at depth $d$, and (e) ${\mathrm{CRF}}_{3\text{-}\mathrm{D}\mathrm{Asym}}$ at depth $d$. The addition of constraints into the CRF model improves the accuracy of the segmentation.
