Exploit the Unknown Gradually: One-Shot Video-Based Person Re-Identification by Stepwise Learning

Pytorch implementation for our paper [Link]. This code is based on the Open-ReID library.

Preparation

Dependencies

• Python 3.6
• PyTorch (version >= 0.2.0)
• h5py, scikit-learn, metric-learn, tqdm

Download datasets

• DukeMTMC-VideoReID: This page contains more details and baseline code.
• MARS: [Google Drive]   [BaiduYun].
• Move the downloaded zip files to ./data/ and unzip here.

Train

For the DukeMTMC-VideoReID dataset:

python3 run.py --dataset DukeMTMC-VideoReID --logs_dir logs/DukeMTMC-VideoReID_EF_10/ --EF 10 --mode Dissimilarity --max_frames 900

For the MARS datasaet:

python3 run.py --dataset mars --logs_dir logs/mars_EF_10/ --EF 10 --mode Dissimilarity --max_frames 900

It takes about 10 hours to train EUG (EF=10%) on DukeMTMC-VideoReID with a GTX1080Ti. Please set the max_frames smaller if your GPU memory is less than 11G.

Performances

The performances varies according to random splits for initial labeled data. To reproduce the performances in our paper, please use the one-shot splits at ./examples/

Future work

In the extended version, We improve EUG by leveraging the remaining unselected data in an unsupervised way, which shows a great performance improvement on the image-based re-ID datasets (Market-1501 and DukeMTMC-reID). [Paper] [Code]
