AlphaPose

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.

News!

  • Apr 2019: MXNet version of AlphaPose is released! It runs at 23 fps on COCO validation set using a single Nvidia 1080Ti GPU!
  • 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: 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 using a single Nvidia 1080Ti GPU!

Installation

Note: For new users or users that are not familiar with TensorFlow or Torch, we suggest using the PyTorch version since it's more user-friendly and runs faster.

  1. Get the code and build related modules.
git clone https://github.com/MVIG-SJTU/AlphaPose.git
cd AlphaPose/human-detection/lib/
make clean
make
cd newnms/
make
cd ../../../
  1. Install Torch and TensorFlow(verson >= 1.2). After that, install related dependencies by:
chmod +x install.sh
./install.sh
  1. 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

Quick Start

  • 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

Output (format, keypoint index ordering, etc.) in doc/output.md.

Speeding Up AlphaPose

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.

Feedbacks

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!
