AlphaPose

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

Quick Start

  • Colab: We provide a colab example for your quick start.

  • Inference: Inference demo

./scripts/inference.sh ${CONFIG} ${CHECKPOINT} ${VIDEO_NAME} # ${OUTPUT_DIR}, optional
  • Training: Train from scratch
./scripts/train.sh ${CONFIG} ${EXP_ID}
  • Validation: Validate your model on MSCOCO val2017
./scripts/validate.sh ${CONFIG} ${CHECKPOINT}

Examples:

Demo using FastPose model.

./scripts/inference.sh configs/coco/resnet/256x192_res50_lr1e-3_1x.yaml pretrained_models/fast_res50_256x192.pth ${VIDEO_NAME}
#or
python scripts/demo_inference.py --cfg configs/coco/resnet/256x192_res50_lr1e-3_1x.yaml --checkpoint pretrained_models/fast_res50_256x192.pth --indir examples/demo/

Train FastPose on mscoco dataset.

./scripts/train.sh ./configs/coco/resnet/256x192_res50_lr1e-3_1x.yaml exp_fastpose

AlphaPose is based on RMPE(ICCV'17), authored by Hao-Shu Fang, Shuqin Xie, Yu-Wing Tai and Cewu Lu, Cewu Lu is the corresponding author. Currently, it is maintained by Jiefeng Li*, Hao-shu Fang*, Yuliang Xiu and Chao Xu.

The main contributors are listed in doc/contributors.md.

TODO

  • Multi-GPU/CPU inference
  • 3D pose
  • add tracking flag
  • PyTorch C++ version
  • Add MPII and AIC data
  • dense support
  • small box easy filter
  • Crowdpose support
  • Speed up PoseFlow
  • Add stronger/light detectors and the mobile pose
  • High level API

We would really appreciate if you can offer any help and be the contributor of AlphaPose.
