A majorization–minimization-based method for nonconvex inverse rig problems in facial animation: algorithm derivation

Automated methods for facial animation are a necessary tool in the modern industry since the standard blendshape head models consist of hundreds of controllers, and a manual approach is painfully slow. Different solutions have been proposed that produce output in real-time or generalize well for dif...
