Face expression generation method based on interactive evolutionary algorithm and expression fusion

The generation of facial expressions has long been a challenging problem. In order to generate user-satisfactory facial expressions, this paper proposes an expression generation method based on an interactive evolutionary algorithm. The method employs an interactive evolutionary algorithm to optimize expression parameters in order to obtain satisfactory face expression parameters. Different face parameters express the fusion of predefined expressions in different parts of the face. By designing the face expression coding, it is possible to achieve a diversity of fusion effects in time and space, thus enabling the realization of a rich animation process of face expressions.
