This paper proposes a simple baseline framework for video-based 2D/3D human pose estimation that can achieve 10 times efficiency improvement over existing works without any performance degradation, named DeciWatch. Unlike current solutions that estimate each frame in a video, DeciWatch introduces a simple yet effective sample-denoise-recover framework that only watches sparsely sampled frames, taking advantage of the continuity of human motions and the lightweight pose representation. Specifically, DeciWatch uniformly samples less than 10% video frames for detailed estimation, denoises the estimated 2D/3D poses with an efficient Transformer architecture, and then accurately recovers the rest of the frames using another Transformer-based network. Comprehensive experimental results on three video-based human pose estimation, body mesh recovery tasks and efficient labeling in videos with four datasets validate the efficiency and effectiveness of DeciWatch.
- Model training and evaluation for 2D pose, 3D pose, and SMPL body representation
- Supporting four popular datasets (Human3.6M, 3DPW, AIST++, Sub-JHMDB) and providing cleaned data of five popular pose estimation backbones(FCN, SPIN, EFT, PARE, SimplePose)
- Versatile visualization toolbox with comparision of input (backbone estimator results) and output(DeciWatch results)
Visualize 2D poses on Sub-JHMDB dataset:
Visualize 3D poses on AIST++ dataset:
Visualize SMPL on 3DPW dataset:
DeciWatch has been implemented and tested on Pytorch 1.10.1 with python >= 3.6. It supports both GPU and CPU inference.
Clone the repo:
git clone https://github.com/cure-lab/DeciWatch.gitWe recommend you install the requirements using conda:
# conda

Please refer to doc/data.md for detailed data information and data preparing.
Note that the training and testing datasets should be downloaded and prepared before training.
You may refer to doc/training.md for more training details.
Run the commands below to start training:
python train.py --cfg [config file] --dataset_name [dataset name] --estimator [backbone estimator you use] --body_representation [smpl/3D/2D] --sample_interval [sample interval N]For example, you can train on 3D position representation of the 3DPW dataset using the backbone estimator SPIN with a sample interval N=10 (sampling ratio=10%) by:
python train.py --cfg configs/config_pw3d_spin.yaml --dataset_name pw3d --estimator spin --body_representation 3D --sample_interval 10Noted that although our main contribution is the high efficiency improvement, using DeciWatch as post processing is also helpful for accuracy and smoothness improvement.
You may refer to doc/evaluate.md for evaluate details on all sampling ratios.

Here, we only provide demo visualization based on offline processed detected poses of specific datasets(e.g. AIST++, Human3.6M, 3DPW, and Sub-JHMDB). To visualize on arbitrary given video, please refer to the inference/demo of MMHuman3D.
Run the commands below to visualize demo:
python demo.py --cfg [config file] --dataset_name [dataset name] --estimator [backbone estimator you use] --body_representation [smpl/3D/2D] --sample_interval [sample interval N]You are supposed to put corresponding images with the data structure:
|-- data
|-- videos
|-- pw3d
|-- downtown_enterShop_00

For example, you can visualize results of 3D position representation on the 3DPW dataset using the backbone estimator SPIN with a sample interval N=10 (sampling ratio=10%) by:
python demo.py --cfg configs/config_pw3d_spin.yaml --dataset_name pw3d --estimator spin --body_representation 3D --sample_interval 10Please refer to the dataset website for the raw images. You may change the config in lib/core/config.py for different visualization parameters.
