3D Face Expression Estimation and Generation from 2D Image Based on a Physically Constraint Model
Takahiro Ishikawa, Shigeo Morishima, Demetri Terzopoulos · 2000
this paper, we propose the strategy of automatic estimation of facial muscle parameters from 2D markers'movements located on a face using a neural network. This corresponds to the non-realtime 3D facial motion capturing from 2D camera image under the physics based condition.
