Modeling and Editing of Peking Opera Facial Makeup Expressions
FeiLong Cai · 2010
In this paper we propose a vector-based hierarchical model for facial makeup's expressions in Peking opera. First we analyze the drawing process of facial makeup in the traditional Peking opera,the shape features of patterns as well as the classification of patterns,and then build a vector pattern bank based on the hierarchical structure of patterns. According to the standards of facial action coding system (FACS),we decompose facial makeup into 40 key action units. During the synthesis process of the facial makeup,users only need to select patterns one by one from the pattern bank to compose needed facial makeup. By using free form deformation (FFD) technique,each expression of action units is obtained. In addition,users may have further control over facial expressions through editing tools provided in the system.
