Abstract: Game developers must increasingly consider the degree to which animation emulates the realistic facial expressions found in cinema. Employing animators and actors to produce cinematic facial animation by mixing motion capture and hand-crafted animation is labour intensive and costly. Neural network controllers have shown promise toward autonomous animation that does not rely on pre-captured movement. Previous work in Computer Graphics and Affective Computing has shown the efficacy of deploying emotion AI in neural networks to animate the faces of autonomous agents. However, a method of evaluating resemblance of neural network behaviour in relation to a live-action human referent has yet to be developed. This paper proposes a combination of statistical methods to evaluate the behavioural resemblance of a neural network animation controller and the single-actor facial emotion corpora used to train it.
