SLS ReID

Datasets

• Download Market1501 Dataset
• Download DukeMTMC-reID Dataset
• Download CUHK03 Dataset
• Download VIPeR Dataset

Dataset preperation

Change the download_path to point to your dataset folder. Comment out multi-query except for Market1501 dataset.

python prepare.py
python re_index.py

Training

• Train the baseline

python train.py 

• Train SLS_ReID

python sls_train.py 

Add --use_dense argument to train using DenseNet121 architecture

Pre-trained models

To generate the GAN label (gan%.list ie gan0.list, gan1.list and gan2.list for three cluster ), run generate_labels_for_gan:

python prepare_gan_data.py

Testing

python test_cuhk03.py --model_path ./cuhk03/model.pth --use_dense
python eval_cuhk03.py
----------
python test_viper.py --model_path ./viper/model.pth --use_dense
%Add --re_rank to get re-ranking with k-reciprocal encoding
----------
python test.py --model_path ./market/model.pth --use_dense
python evaluate.py
python evaluate_rerank.py 
%Add --multi for multi-query evaluation
