Fig. 5.

Visual comparison of the registration results with human segmentation results, based on contrast-enhanced micro-CT images. For every pair of comparison, “S” stands for human segmentation result, and “R” stands for registration result. The contours of the registration results demonstrate the mean shapes [ ${\mathbf{M}}_{\text{Reg}}^{\mathbf{H}}$ and ${\overline{\mathbf{M}}}_{\text{Reg}}^{\mathbf{L}}$ in (7) and (8)] of the registered organs.
