Steps in the thickness computation pipeline. (A): a surface mesh of the combined segmentation of the CA, SUB, ERC and PRC structures in the right hemisphere in one subject; the step edges in the segmentation can be observed. (B): the surface mesh for the same set of structures in the unbiased population template constructed from 85 ASHS segmentations; the surface of the mesh is much smoother. (C): the smooth template surface warped to the space of the subject’s segmentation. (D): superimposition of the segmentation (A) and the warped template (C) showing that (C) provides a smooth approximation to (A). (E): Pruned Voronoi skeleton computed from the warped template surface. (F) Thickness (distance to the skeleton) mapped onto the boundary of the warped template.
