Figure 9. Estimated 2D eye and mouth models (Left: Akiyo; Right: Miss
America).
Figure 10. Estimated eyebrows, nose, chin and cheek contours (Left:
Akiyo; Right: Miss America). Displayed eye and mouth middle positions are
used for determining search areas for the other facial features.
for the eye and mouth corner positions is 1.8 pel. The estimate error for lip
thickness and for lip opening heights is 1.5 pel on average, while the error for the
eyelid opening heights amounts to 2.0 pels.
Figure 10 shows some results for the estimation of the other facial features
(eyebrows, nose, chin and cheek contours) of the high complexity mode. The
estimate error for the eyebrows is 2.7 pels on average and for the sides of the
nose is 1.8 pel. The estimate error for chin and cheek contours is 2.7 pels on
average.
