An example of a Karcher mean face for eight faces belonging to different people is shown in
Figure 3.16. This figure illustrates the mean face of faces belonging to different persons. Several
examples of using the Karcher mean to compute average noses are shown in Figure 3.17.
3.7.2 Learning Statistical Models in Shape Space
We have a way of estimating the Karcher mean of a sample set on a nonlinear manifold. What
about principal component analysis? The core of this problem, in our representation of facial
surfaces by curves, is to take a partial facial curve and predict its completion. The sources of
