  • Dec 2019: v0.3.0 version of AlphaPose is released! Smaller model, higher accuracy!
  • Apr 2019: MXNet version of AlphaPose is released! It runs at 23 fps on COCO validation set.
  • Feb 2019: CrowdPose is integrated into AlphaPose Now!
  • Dec 2018: General version of PoseFlow is released! 3X Faster and support pose tracking results visualization!
  • Sep 2018: v0.2.0 version of AlphaPose is released! It runs at 20 fps on COCO validation set (4.6 people per image on average) and achieves 71 mAP!


AlphaPose is an accurate multi-person pose estimator, which is the first open-source system that achieves 70+ mAP (75 mAP) on COCO dataset and 80+ mAP (82.1 mAP) on MPII dataset. To match poses that correspond to the same person across frames, we also provide an efficient online pose tracker called Pose Flow. It is the first open-source online pose tracker that achieves both 60+ mAP (66.5 mAP) and 50+ MOTA (58.3 MOTA) on PoseTrack Challenge dataset.

AlphaPose supports both Linux and Windows!

COCO 17 keypoints

Halpe 26 keypoints + tracking

Halpe 136 keypoints + tracking
