Abstract :
We propose an adaptive head modeling method which can be selective according to the purpose and available input resources. In each case, we utilize the generic head model for the head reconstruction, which is constructed based on the facial anatomy and the hierarchical structure. This model is capable of simulating a facial dynamics by the physics-based computation. For the head reconstruction, we account for the input resources as facial images, X-ray images, 3D-CT, and 3D digitizer. The proposed methods are photogrammetric technique using two directional facial images and X-ray images. Using the extracted shape information from those inputs, the generic head model is flexibly deformed to match the target head so that it is useful for wide aims. A facial dynamics simulation and a facial surgery simulation are introduced as the concrete applications
