Abstract
Digital-human facial Micro-expression generation suit constructs the film CG’s basic model. This can be used to upgrade the basic CG digital-human to an intelligent digital-human. Digital humans lack the reality in micro-expressions, so the effect is lost during application in film or interactive games. This paper introduced the face plus-in of a soft mod manipulator, accurately calculated the expression feature points by using the blend shape technology, and proposed a method to produce CG digital human micro-expressions using markerless point capture. The study showed that this micro-expression technology can be applied to realistic digital humans. Finally, this technical method of micro-expression production can achieve a satisfactory in-depth experience effect for the audience in virtual studio platforms, CG films, and interactive games. This study proves the feasibility and importance of this technology.
