Summary:
Active Appearance Models (AAMs) are parametric facial models which have been widely used for facial features localization. In order to localize facial features, AAMs used an optimization method which finds local minima. As a result, AAMs cannot always localize facial features exactly when initial locations of facial features are far from the ground truth locations of them. To solve this problem, we propose a simple preprocessing method which finds initial locations of facial features such as eyes, nostrils, and lip corners. Experimental results showed that the proposed method was robust to moderate pose variation, illumination condition changes, complex background, and glasses wearers.
