AlphaPose-real-time full-body multi-person pose estimation and tracking system

It is the first open source system to achieve 70+ mAP (75 mAP) on the COCO dataset and 80+ mAP (82.1 mAP) on the MPII dataset. To match poses corresponding to the same person in frames, an efficient online pose tracker called Pose Flow is also provided. It is the first open source online pose tracker to achieve 60+ mAP (66.5 mAP) and 50+ MOTA (58.3 MOTA) on the PoseTrack Challenge dataset. AlphaPose supports Linux and Windows.
