TraND

This is the code for the paper "Jinkai Zheng, Xinchen Liu, Chenggang Yan, Jiyong Zhang, Wu Liu, Xiaoping Zhang and Tao Mei: TraND: Transferable Neighborhood Discovery for Unsupervised Cross-domain Gait Recognition. ISCAS 2021" (MSA-TC “Best Paper Award - Honorable Mention”)

Requirements

• Conda
• GPUs
• Python 3.7
• PyTorch 1.1.0

Installation

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

git clone https://github.com/JinkaiZheng/TraND.git
cd TraND
conda create --name py37torch110 python=3.7
conda activate py37torch110
conda install pytorch==1.1.0 torchvision==0.3.0 cudatoolkit=10.0 -c pytorch
pip install -r requirements

Data Preparation

Download CASIA-B and OU-LP

Data Pretreatment

pretreatment_casia.py and pretreatment_oulp.py use the alignment method in this paper. In the case of CASIA-B dataset, you need to run the command:

python GaitSet/pretreatment_casia.py --input_path='root_path_of_raw_dataset' --output_path='./data/CASIA-B'

Data Structrue

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

./data
├── CASIA-B
│  ├── 001
│     ├── bg-01
│        ├── 000
│           └── 001-bg-01-000-001.png
├── OULP
│  ├── 0000024
│     ├── Seq00
│        ├── 55
            └── 00000061.png

Train

Stage I: Supervised Prior Knowledge Learning on Source Domain

Training the GaitSet model in the source domain, run this command:

 python GaitSet/train.py --data "casia-b"

Our models: CASIA_best_model and OULP_best_model

Stage II: Transferable Neighbor Discovery on Target Domain

Fine-tuning the GaitSet model in the target domain with TraND method, run this command:

sh Experiment.sh

Our models: CASIA2OULP_best_model and OULP2CASIA_best_model

Test

Testing the model in self domain, such as CASIA-B dataset, run this command:

python GaitSet/test.py --data "casia-b"

Testing the model in cross domain, such as CASIA-B -> OU-LP dataset, run this command:

python GaitSet/test_cross.py --source "casia-b" --target "oulp"
