%X The synthesis of human expression texture,is an important factor in realistic animation of human face.Traditional expression synthesis technologies are only concerned about the geometrical transformation of facial features.However,they do not deal with expression details.Recent researches try to involve synthesis of expression texture,but most of them can only generate expression details from given expression samples using one-to-one method,leading to the limited application areas.A new algorithm is raised by effectively combining wavelet pyramid decomposition and expression ratio image.This algorithm can not only map the expression texture,but also generate expression animation.The expression exaggeration factor is also parameterized so that the user can control the expression freely.The algorithm proves to be effective.
