Redundancy reduction in 3D facial motion capture data for animation
Daniela I. Wellein, Cristóbal Curio, HH Bülthoff · 2007
Research on the perception of dynamic faces often requires real-time animations with low latency. With an adaptation of principal feature analysis [Cohen et al. 2002], we can reduce the number of facial motion capture markers by 50%, while retaining the overall animation quality.
