引述
"We present a new method for the animation of 3D neural head models."
"Our contribution enhances the fidelity and realism of video-driven facial animations."
"Our intuition on why the residual features improve animation during inference is that they reduce the likelihood that the network learns spurious correlations between input expression features and target animation parameters."
