To improve the convenience of triangulation based image warping algorithm, an automatic approach for facial expression deformation is presented. In order to guarantee the expression deformation is dealt with high quality and conveniently, the approach uses two key technologies: the PSO detection and the affine transformation. The PSO algorithm is utilized to search the optimal position of rectangle containing face and eyes. The affine transformation is applied to warp related triangles to deform expression. The simulation results show that this method can produce natural smile expression, without marking the spots manually, especially works well for some shy smile expressions.
