Figure 18. Two representative snapshots of purely cloned visemes exemplify
that cloning (Noh et al., 2001) does not always result in convincing shapes.
et al., 2001). The animation shows a few flaws, which become stronger as the
morph gets closer to the boy's face. Some of these flaws are highlighted in Figure
18 (but they are more outspoken if seen as a video). This example shows that
cloning alone does not suffice to yield realistic animation of speech.
A third example shows the result of our full viseme personalization. The three
faces on the left-hand side of Figure 19 are three of the 10 example faces used
to create the hyper-plane. The face on the right-hand side has been animated by
first projecting it onto the hyper-plane, weighing the visemes of the examples
accordingly, and finally cloning these weighted visemes to the original face.
Figure 19. Combination of the same viseme (represented by the faces in the
upper row) are combined and cloned onto a novel face according to its
physiognomy (face in the center).
