MixSTE: Seq2seq Mixed Spatio-Temporal Encoder for 3D Human Pose Estimation in Video

Official implementation of CVPR 2022 paper(MixSTE: Seq2seq Mixed Spatio-Temporal Encoder for 3D Human Pose Estimation in Video).

Note: Here are core codes of our work. This work is based on the VideoPose3D, some fundamental codes canbe found there. At the same time, We are organizing codes and prepare to submit to the mmpose as soon as possible.

Visualization of our method and ground truth on Human3.6M

Environment

The code is conducted under the following environment:

• Ubuntu 18.04
• Python 3.6.10
• PyTorch 1.8.1
• CUDA 10.2

You can create the environment as follows:

conda env create -f requirements.yaml

Dataset

The Human3.6M dataset and HumanEva dataset setting follow the VideoPose3D. Please refer to it to set up the Human3.6M dataset (under ./data directory).

The MPI-INF-3DHP dataset setting follows the MMPose. Please refer it to set up the MPI-INF-3DHP dataset (also under ./data directory).

Evaluation

• Download the checkpoints from Baidu Disk(wnjf);

Then run the command below (evaluate on 243 frames input):

python run.py -k cpn_ft_h36m_dbb -c <checkpoint_path> --evaluate <checkpoint_file> -f 243 -s 243

Training from scratch

Training on the 243 frames with two GPUs:

python run.py -k cpn_ft_h36m_dbb -f 243 -s 243 -l log/run -c checkpoint -gpu 0,1

if you want to take place of attention module with more efficient attention design, please refer to the rela.py, routing_transformer.py, and linearattention.py. These efficient design are coming from previous works:

• https://github.com/rishikksh20/rectified-linear-attention
• https://github.com/lucidrains/routing-transformer
• https://arxiv.org/abs/2006.04768
