This paper addresses the problem of facial landmark localization and tracking from a single camera. We present a two-stage cascaded deformable shape model to effectively and efficiently localize facial landmarks with large head pose variations. In initialization stage, we propose a group sparse optimized mixture model to automatically select the most salient facial landmarks. By introducing 3D face...
In this paper, we propose a novel method for detecting and tracking landmark facial features on purely geometric 3D and 4D range models. Our proposed method involves fitting a new multi-frame constrained 3D temporal deformable shape model (TDSM) to range data sequences. We consider this a temporal based deformable model as we concatenate consecutive deformable shape models into a single model driven...
