A deep facial landmarks detection with facial contour and facial components constraint

In this paper, we propose a new facial landmarks detection method based on deep learning with facial contour and facial components constraints. The proposed deep convolutional neural networks (DCNNs) for facial landmark detection consists of two deep networks: one DCNN is to detect landmarks constrained on the facial contour and the other is to detect landmarks constrained on facial components. A novel DCNN structure for the landmarks detection with facial component constraints is proposed, which branches the network at higher layers in order to capture the intricate local facial components features. Moreover, a novel learning strategy is proposed to learn the DCNN for detecting the landmarks on the facial contour by exploiting the relationship between facial contour landmarks and those on facial components. Experimental results have shown that the proposed method outperforms the state-of-the-art FLD methods.
