Person Re-id in the 3D Space

Python 3.6 License: MIT

[Pdf] [Code] [中文解读]

Thanks for your attention. In this repo, we provide the code for the paper [Parameter-Efficient Person Re-identification in the 3D Space ], published at IEEE Transactions on Neural Networks and Learning Systems (TNNLS) 2022.

News

  • 9 Mar 2023 Market-1501 is in 3D. Please check our single 2D to 3D reconstruction work https://github.com/layumi/3D-Magic-Mirror.

  • 29 Sep 2022. I updated Circle loss, parameter count and the latest snapshots trained on 4 datasets, including Market, Duke, CUHK and MSMT, in /snapshots. You can directly test it after dataset preparing.

  • 31 Jul 2021. Circle loss is added. For the fair comparison with circle loss, I re-train almost all the models with a bigger batch size. The results are updated in the latest arXiv version.

  • 30 Oct 2020. I simply modify code on three points to further improve the performance:

  1. More training epochs help; (Since we are trained from scratch)

  2. I replace the dgl to more efficient KNN implementation to accelebrate training; (DGL does not optimize KNN very well, and Matrix Multiplication works quicker. )

  3. For MSMT-17 and Duke, some classes contain too many images, while other categories are under-explored. I apply the stratified sampling (--balance), which takes training samples of each class with equal probability.

  • You may directly download my generated 3D data of the Market-1501 dataset at [OneDrive] or [GoogleDrive], and therefore you could skip the data preparation part. Just put the datasets in the same folder of the code.

Prerequisites

  • Python 3.6 or 3.7
  • GPU Memory >= 4G (e.g., GTX1080)
  • Pytorch = 1.4.0 (Not Latest. Latest version is incompatible, since it changes the C++ interfaces.)
  • dgl

Install

Here I use the cuda10.1 by default.

conda create --name OG python=3.7
conda activate OG
conda install pytorch=1.4.0 torchvision=0.5.0 cudatoolkit=10.1 -c pytorch
conda install matplotlib requests
conda install -c dglteam dgl-cuda10.1=0.4.3
pip install -r requirements.txt

If you face any error, you may first try to re-install open3d. It helps. And make sure the gcc version is larger than 5.4.0. If you do not have the sudo permission, you may install gcc by conda as follows:

conda install -c brown-data-science gcc          (which is gcc-5.4.0)
gcc -v                                          (to see whether installation is successful)
ln libstdc++.so.6.0.26 libstdc++.so.6            (update lib in /anaconda3/env/OG/lib)
conda install gxx_linux-64
conda install gcc_linux-64

Prepare Data

I remove all 3D faces and only keep 3D points positions&RGB to save the storage & loading burden. You can use any text readers (such as vim) to see my generated obj files.

  • 2D Part Download Market-1501, DukeMTMC-reID or MSMT17 and unzip them in the ../

Split the dataset and arrange them in the folder of ID by the following code.

python prepare_market.py # You may need to change the download path. 
python prepare_duke.py
python prepare_MSMT.py

Link the 2DDataset to this dir.

ln -s ../Your_Market/pytorch  ./2DMarket
ln -s ../Your_Duke/pytorch  ./2DDuke
ln -s ../Your_MSMT/pytorch  ./2DMSMT

Pre-trained Models

Since OG-Net is really small, I has included trained models in this github repo ./snapshot.

If the model is trained on CUHK, Duke or MSMT, I will add dataset name in the model name, otherwise the model is trained on Market.

[ModelNet Performance]

I add OG-Net code to https://github.com/layumi/dgcnn
Results on ModelNet are 93.3 Top1 Accuracy / 90.5 MeanClass Top1 Accuracy.
