Exploiting Temporal Contexts with Strided Transformer for 3D Human Pose Estimation

This repo is the official implementation of Exploiting Temporal Contexts with Strided Transformer for 3D Human Pose Estimation in Pytorch.

Dependencies

• Cuda 11.1
• Python 3.6
• Pytorch 1.7.1

Dataset setup

Please download the dataset from Human3.6m website and refer to VideoPose3D to set up the Human3.6M dataset ('./dataset' directory).

${POSE_ROOT}/
|-- dataset
|   |-- data_3d_h36m.npz
|   |-- data_2d_h36m_gt.npz
|   |-- data_2d_h36m_cpn_ft_h36m_dbb.npz

Download pretrained model

The pretrained model can be found in Google_Drive, please download it and put in the './checkpoint' dictory.

Test the model

To test on pretrained model on Human3.6M with 351-frames:

python main.py --frames 351 --refine --reload 1  --refine_reload 1 --previous_dir 'checkpoint/351'

Train the model

To train on Human3.6M with 351-frame:

python main.py --frames 351 --train 1 \

After training for several epoches, add refine module

python main.py --frames 351 --train 1 --refine --lr 1e-5 --reload 1 --previous_dir [your model saved path] \
