KeyPoint Detection Models

Introduction

  • The keypoint detection part in PaddleDetection follows the state-of-the-art algorithm closely, including Top-Down and BottomUp methods, which can meet the different needs of users.

Note：The AP results of Top-Down models are based on bounding boxes in GroundTruth.

We also release PP-TinyPose, a real-time keypoint detection model optimized for mobile devices. Welcome to experience.

Getting Start

1. Environmental Installation

​ Please refer to PaddleDetection Installation Guild to install PaddlePaddle and PaddleDetection correctly.

2. Dataset Preparation

​ Currently, KeyPoint Detection Models support COCO and MPII. Please refer to Keypoint Dataset Preparation to prepare dataset.

​ About the description for config files, please refer to Keypoint Config Guild.

  • Note that, when testing by detected bounding boxes in Top-Down method, We should get bbox.json by a detection model. You can download the detected results for COCO val2017 (Detector having human AP of 56.4 on COCO val2017 dataset) directly, put it at the root path (PaddleDetection/), and set use_gt_bbox: False in config file.

3、Training and Testing

​ Training on single gpu:

#COCO DataSet
CUDA_VISIBLE_DEVICES=0 python3 tools/train.py -c configs/keypoint/higherhrnet/higherhrnet_hrnet_w32_512.yml

#MPII DataSet
CUDA_VISIBLE_DEVICES=0 python3 tools/train.py -c configs/keypoint/hrnet/hrnet_w32_256x256_mpii.yml

​ Training on multiple gpu:

#COCO DataSet
CUDA_VISIBLE_DEVICES=0,1,2,3 python3 -m paddle.distributed.launch tools/train.py -c configs/keypoint/higherhrnet/higherhrnet_hrnet_w32_512.yml

#MPII DataSet
CUDA_VISIBLE_DEVICES=0,1,2,3 python3 -m paddle.distributed.launch tools/train.py -c configs/keypoint/hrnet/hrnet_w32_256x256_mpii.yml

​ Evaluation

#COCO DataSet
CUDA_VISIBLE_DEVICES=0 python3 tools/eval.py -c configs/keypoint/higherhrnet/higherhrnet_hrnet_w32_512.yml

#MPII DataSet
CUDA_VISIBLE_DEVICES=0 python3 tools/eval.py -c configs/keypoint/hrnet/hrnet_w32_256x256_mpii.yml

#If you only need the prediction result, you can set --save_prediction_only. Then the result will be saved at output/keypoints_results.json by default.
CUDA_VISIBLE_DEVICES=0 python3 tools/eval.py -c configs/keypoint/higherhrnet/higherhrnet_hrnet_w32_512.yml --save_prediction_only

​ Inference

​ Note：Top-down models only support inference for a cropped image with single person. If you want to do inference on image with several people, please see "joint inference by detection and keypoint". Or you can choose a Bottom-up model.

CUDA_VISIBLE_DEVICES=0 python3 tools/infer.py -c configs/keypoint/higherhrnet/higherhrnet_hrnet_w32_512.yml -o weights=./output/higherhrnet_hrnet_w32_512/model_final.pdparams --infer_dir=../images/ --draw_threshold=0.5 --save_txt=True

​ Deploy Inference

#export models
python tools/export_model.py -c configs/keypoint/higherhrnet/higherhrnet_hrnet_w32_512.yml -o weights=output/higherhrnet_hrnet_w32_512/model_final.pdparams

#deploy inference
