Gait3D-Benchmark

This is the code for the paper "Jinkai Zheng, Xinchen Liu, Wu Liu, Lingxiao He, Chenggang Yan, Tao Mei: Gait Recognition in the Wild with Dense 3D Representations and A Benchmark. (CVPR 2022)". The official project page is here.

What's New

  • [Mar 2022] Another gait in the wild dataset GREW is supported.
  • [Mar 2022] Our Gait3D dataset and SMPLGait method are released.

Installation

You can replace the second command from the bottom to install pytorch based on your CUDA version.

git clone https://github.com/Gait3D/Gait3D-Benchmark.git
cd Gait3D-Benchmark
conda create --name py37torch160 python=3.7
conda activate py37torch160
conda install pytorch==1.6.0 torchvision==0.7.0 cudatoolkit=10.2 -c pytorch
pip install tqdm pyyaml tensorboard opencv-python tqdm py7zr tabulate termcolor

Data Preparation

Please download the Gait3D dataset by signing an agreement. We ask for your information only to make sure the dataset is used for non-commercial purposes. We will not give it to any third party or publish it publicly anywhere.

Data Pretreatment

Run the following command to preprocess the Gait3D dataset.

python misc/pretreatment.py --input_path 'Gait3D/2D_Silhouettes' --output_path 'Gait3D-sils-64-44-pkl' --img_h 64 --img_w 44
python misc/pretreatment.py --input_path 'Gait3D/2D_Silhouettes' --output_path 'Gait3D-sils-128-88-pkl' --img_h 128 --img_w 88
python misc/pretreatment_smpl.py --input_path 'Gait3D/3D_SMPLs' --output_path 'Gait3D-smpls-pkl'

Data Structrue

After the pretreatment, the data structure under the directory should like this

├── Gait3D-sils-64-44-pkl
│  ├── 0000
│     ├── camid0_videoid2
│        ├── seq0
│           └──seq0.pkl
