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 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') inconfig/defaults.py
Download dataset to toDataset/ from 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://github.com/lingxiao-he/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')"
