OpenPose is the first open source real-time two-dimensional pose estimation system for multiple people in an image or video. It was mainly developed by the students and faculties of Carnegie Mellon University (CMU). The title of the paper is OpenPose: Realtime Multi-Person 2D Pose Estimation Using Part Affinity Fields, and the authors are Zhe Cao, Gines Hidalgo, Tomas Simon, Shih-En-Wei, and Yaser Sheikh.
