Abstract

We propose a new automatic head modeling system to generate individualized head models which can express person-specific facial expressions. The head modeling system consists of two core processes. The head modeling process with the proposed automatic mesh completion generates a whole head model only from facial range scan data. The key shape generation process generates key shapes for the generated head model based on physics-based facial muscle simulation with an individual muscle layout estimated from subject's facial expression videos. Facial animations considering personal characteristics can be synthesized using the individualized head model and key shapes. Experimental results show that the proposed system can generate head models where 84% of subjects can identify themselves. Therefore, we conclude that our head modeling system is effective to games and entertainment systems like a Future Cast System.
