based on a single component (1st and 3rd column) and multiple
components (2nd and 4th column) to scan data in blue. Results from the front and side view, show a
qualitative better fit of the multiple components to the scan data
Our time to process a raw scan requires ca. 3 seconds for the face segmentation, ca. 1 second
for the coarse fitting, and ca. 30 seconds for the fine fitting on a Pentium IV 2.8 GHz. Blanz
method reported ca. 4 minutes on a 3.4 GHz Xeon processor, but includes texture fitting as
well. Huang et al. (2006) report for their deformation model a matching error of 1.2 mm after a
processing time of 4.6 minutes. Recently, Amberg et al. (2008) proposed a competitive fitting
time of 40 to 90 seconds for their face model with 310 model coefficients and 11.000 vertices.
