QAConv
Interpretable and Generalizable Person Re-Identification with Query-Adaptive Convolution and Temporal Lifting
This PyTorch code is proposed in our paper [1].
Requirements
- Pytorch (>1.0)
- sklearn
Usage
Download some public datasets (e.g. Market-1501, DukeMTMC-reID, CUHK03-NP, MSMT) on your own, extract them in some folder, and then run the followings.
Training and test
python main.py --dataset market --testset duke[,market,msmt] [--data-dir ./data] [--exp-dir ./Exp]
For more options, run "python main.py --help". For example, if you want to use the ResNet-152 as backbone, specify "-a resnet152". If you want to train on the whole dataset (as done in our paper for the MSMT17), specify "--combine_all".
Test only
python main.py --dataset market --testset duke[,market,msmt] [--data-dir ./data] [--exp-dir ./Exp] --evaluate
Performance
Performance (%) of QAConv with ResNet-152 under direct cross-dataset evaluation without transfer learning or domain adaptation:
| Method | Training set | Test set | Rank-1 | mAP |
|---|---|---|---|---|
| QAConv | Market | Duke | 54.4 | 33.6 |
| QAConv + RR + TLift | Market | Duke | 70.0 | 61.2 |
| QAConv | MSMT | Duke | 72.2 | 53.4 |
| QAConv + RR + TLift | MSMT | Duke | 82.2 | 78.4 |
| QAConv | Duke | Market | 62.8 | 31.6 |
| QAConv + RR + TLift | Duke | Market | 78.7 | 58.2 |
| QAConv | MSMT | Market | 73.9 | 46.6 |
| QAConv + RR + TLift | MSMT | Market | 88.4 | 76.0 |
| QAConv | Market | MSMT | 25.6 | 8.2 |
| QAConv | Duke | MSMT | 32.7 | 10.4 |
| QAConv | Market | CUHK03-NP | 14.1 | 11.8 |
| QAConv | Duke | CUHK03-NP | 11.0 | 9.4 |
| QAConv | MSMT | CUHK03-NP | 32.6 | 28.1 |
