# TPAMI 2021 ReID-Survey with a Powerful AGW Baseline
Deep Learning for Person Re-identification:  A Survey and Outlook. PDF with supplementary materials. [arXiv](https://arxiv.org/abs/2001.04193v2)

- An implementation of AGW for cross-modality visible-infrared Re-ID is [HERE](https://gitee.com/wrboone/Cross-Modal-Re-ID-baseline).

- An implementation of AGW for video Re-ID is [HERE](https://gitee.com/wrboone/ReID-Survey/tree/master/video-reid-AWG)

- An implementation of AGW for partial Re-ID is [HERE](https://gitee.com/wrboone/ReID-Survey/blob/master/Experiment-AGW-partial.sh).

A simplified introduction in Chinese on [知乎](https://zhuanlan.zhihu.com/p/342249413).

## Highlights

- A comprehensive survey with in-depth analysis for closed- and open-world person Re-ID in recent years (2016-2020).

- A new evaluation metric, namely mean Inverse Negative Penalty (mINP), which measures the ability to find the hardest correct match.

- A new AGW baseline with non-local Attention block, Generalized mean pooling and Weighted regularization triplet. It acheieves competitive performance on FOUR challenging Re-ID tasks, including single-modality image-based Re-ID, video-based Re-ID, Partial Re-ID and [cross-modality](https://github.com/mangye16/Cross-Modal-Re-ID-baseline) Re-ID.

### Quick Start

#### 1. Prepare dataset 
Create a directory to store reid datasets under this repo, taking Market1501 for example
```
cd ReID-Survey
mkdir toDataset
```
- Set ```_C.DATASETS.ROOT_DIR = ('./toDataset')``` in```config/defaults.py```
- Download dataset to toDataset/ from [http://www.liangzheng.org/Project/project_reid.html](http://www.liangzheng.org/Project/project_reid.html)

- Extract dataset and rename to ```market1501```. The data structure would like:
```
toDataset
    market1501 
        bounding_box_test/
        bounding_box_train/
        ......
```

Partial-REID and Partial-iLIDS datasets are provided by https://gitee.com/wrboone/Partial-Person-ReID

#### 2. Install dependencies

  - pytorch=1.0.0
  - torchvision=0.2.1
  - pytorch-ignite=0.1.2
  - yacs
  - scipy=1.2.1
  - h5py
  
#### 3. Train

To train a AGW model with on Market1501 with GPU device 0, run similarly:
```
python3 tools/main.py --config_file='configs/AGW_baseline.yml' MODEL.DEVICE_ID "('0')" DATASETS.NAMES "('market1501')" OUTPUT_DIR "('./log/market1501/Experiment-AGW-baseline')"
```

#### 4. Test

To test a AGW model with on Market1501 with weight file ```'./pretrained/dukemtmc_AGW.pth'```, run similarly:
```
python3 tools/main.py --config_file='configs/AGW_baseline.yml' MODEL.DEVICE_ID "('0')" DATASETS.NAMES "('market1501')"  MODEL.PRETRAIN_CHOICE "('self')" TEST.WEIGHT "('./pretrained/market1501_AGW.pth')" TEST.EVALUATE_ONLY "('on')" OUTPUT_DIR "('./log/Test')"
```
