This paper presents a method of multi-curve spectrum representation of facial movements and expressions. Based on 3DMCF (3D muscle-controlled facial) model, facial movements and expressions are controlled by 21 virtual muscles. So, facial movements and expressions can be described by a group of time-varying curves of normalized muscle contraction, called multi-curve spectrum. The structure and basic characters of multi-curve spectrum is introduced. The performance of the proposed method is among the best. This method needs small quantity of data, and is easy to apply. It can also be used to transplant facial animation between different faces.
