With the spread of the epidemic in the world, wearing masks has become the most simple and effective way to block the COVID-19. For the lack of data and model design to fit the epidemic scene, we propose an integrated masked face recognition system with three cascaded convolutional neural networks. Firstly, a SSD model is used to detect masked face to eliminate the interference of irrelevant background. Then, we use an Hourglass network to regress the key points of the occluded face and crop the aligned eye-brow area without mask. Finally, we finetune a pretrained FaceNet to fully adapt to the data of eye-brow regions. Experiments on numbers of laboratory and wild images proved that our method can recognize the subjects with mask effectively.
