Abstract: Current facial landmark detection algorithm has achieved promising recognition rates in constrained environment, but in unconstrained environment it is still susceptible to various factors such as non-uniform ambient illumination, wide range of angles, variations in pose, occlusion, and blur. To deal with these problems, we propose a cascade convolutional network to improve the accuracy and robustness of the landmark detection. In face detection, we propose a DPM-CNN model based on Light-VGGNet, which introduces the location information of the facial features. In this way, the detection accuracy is improved and the impact of face detection on the positioning of landmarks is reduced. In facial landmark detection, this algorithm adopts two different layers of cascade networks progressively to complete the positioning of the internal and external landmarks. Finally, on the FDDB dataset, this new algorithm is proved to have higher accuracy rate and detection speed than other algorithms in face detection or in facial landmark location. This algorithm is also robust in an unconstrained environment.
