 Please cite these papers in your publications if it helps your research. For standard OpenPose, cite `[Cao et al. 2018]`. If you also use the hand and face keypoint detectors, then cite `[Cao et al. 2018]` and `[Simon et al. 2017]` (the face detector was trained using the same procedure than the hand detector).
