The Face Landmark Network is used to detect five key points of a face. The five points include the left eye, the right eye, nose, left lip of mouth, right lip of mouth. This network is used to correct face direction before face feature extraction. The input image should be a face which is detected by the face detection network. The outputs of the network are 5 key points. The 5 key points are normalized. The following image show the result of face detection.
