Alpha Pose is an accurate multi-person pose estimator, which is the first real-time open-source system that achieves 70+ mAP (72.3 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.
Now PyTorch 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!

cd ../../../- Install Torch and TensorFlow(verson >= 1.2). After that, install related dependencies by:
chmod +x install.sh
./install.sh- Run fetch_models.sh to download our pre-trained models. Or download the models manually: output.zip(Google drive|Baidu pan), final_model.t7(Google drive|Baidu pan)
chmod +x fetch_models.sh
./fetch_models.sh- Demo: Run AlphaPose for all images in a folder and visualize the results with:
./run.sh --indir examples/demo/ --outdir examples/results/ --vis
The visualized results will be stored in examples/results/RENDER. To easily process images/video and display/save the results, please see doc/run.md. If you get any problems, you can check the doc/faq.md.
- Video: You can see our video demo here.
Output (format, keypoint index ordering, etc.) in doc/output.md.
We provide a fast mode for human-detection that disables multi-scale testing. You can turn it on by adding --mode fast.
And if you have multiple gpus on your machine or have large gpu memories, you can speed up the pose estimation step by using multi-gpu testing or large batch tesing with:
./run.sh --indir examples/demo/ --outdir examples/results/ --gpu 0,1,2,3 --batch 5
It assumes that you have 4 gpu cards on your machine and each card can run a batch of 5 images. Here is the recommended batch size for gpu with different size of memory:
GPU memory: 4GB -- batch size: 3
GPU memory: 8GB -- batch size: 6
GPU memory: 12GB -- batch size: 9
See doc/run.md for more details.
If you get any problems, you can check the doc/faq.md first. If it can not solve your problems or if you find any bugs, don't hesitate to comment on GitHub or make a pull request!
