Method based on a joint three-dimensional facial expression dictionary removed

The present invention discloses a method for removing the three-dimensional facial expression based on the combined dictionary, comprises the following steps: (1), a three-dimensional non-rigid facial alignment; (2), combined dictionary learning; (3), based on the removal of residual expression the face region extraction; (4), template-directed Poisson deformation. The main solution is inputted into automatic face expression with corresponding technical problems a neutral face, treated by the process of the present invention, it is possible automatically with a three-dimensional face data input expression into its corresponding neutral face data.
