In facial expression analysis, two principle approaches to extract facial features are geometric featurebased methods and appearance-based methods such as Gabor filters. In this paper, we combine these approaches in a feature-based system to recognize Facial Action Coding System (FACS) action units (AUs) in a complex database. The geometric facial features (including mouth, eyes, brows, and cheeks) are extracted using multi-state facial component models. After extraction, these features are… CONTINUE READING
