Modeling Expressions of Peking Opera Facial Make-Ups

This paper presents a framework for modeling expressions of Peking Opera facial make-ups. We first abstract patterns in the facial make-ups by use of flood filling and 8-connected boundary tracing algorithms, and then pick up feature points from abstracted pattern boundaries with the Douglas-Peucker algorithm. A pattern bank is constructed with those feature points corresponding to the forehead patterns, eyebrow patterns, orbit patterns and mouth patterns. During the synthesis phase, users may pick up appropriate patterns from the pattern bank to compose new facial make-ups. Our system reconstructs the original patterns by interpolating corresponding feature points with the spline. Expressions of facial make-ups can be obtained by deforming pattern with the Radial basis function interpolation on either predefined or interactively specified facial feature points. Examples of both synthesized facial make-ups and facial expressions of facial make-ups are given in the paper.
