We present a novel multi-scale representation and acquisition
method for the animation of high-resolution facial geometry and
wrinkles. We first acquire a static scan of the face including reflectance
data at the highest possible quality. We then augment a
traditional marker-based facial motion-capture system by two synchronized
video cameras to track expression wrinkles. The resulting
model consists of high-resolution geometry, motion-capture
data, and expression wrinkles in 2D parametric form. This combination
represents the facial shape and its salient features at multiple
scales. During motion synthesis the motion-capture data
deforms the high-resolution geometry using a linear shell-based
mesh-deformation method. The wrinkle geometry is added to the
facial base mesh using nonlinear energy optimization. We present
the results of our approach for performance replay as well as for
wrinkle editing.
