Automatic face replacement for a humanoid robot with 3D face shape display

In this paper, we propose a method to apply any new face to a retro-projected 3D face system, the Mask-bot, which we have developed as a human-robot interface. The robot face using facial animation projected onto a 3D face mask can be quickly replaced by a new face based on a single frontal image of any person. Our contribution is to apply an automatic face replacement technique with the modified texture morphable model fitting to the 3D face mask. Using our technique, a face model displayed on Mask-bot can be automatically replaced within approximately 3 seconds, which makes Mask-bot widely suitable to applications such as video conferencing and cognitive experiments.
