Usage

Dependencies

• Python3.6
• PyTorch(0.2.0)
• torchvision(0.2.0)
• Market1501 dataset
• MARS dataset
• CUHK03 dataset
• DukeMTMC-reID dataset

Usage

Training Dataset Preprocessing

Use the following command to preprocess the person re-id dataset.

python create_market_dataset.py --path <root_path_of_dataset>

Train

Use the following command to set up the training.

./train.sh <nettype> <GPU> <train_dataset_path> <checkpoint_name>

where <nettype> can be either dare_R or dare_D

Extract Features

Use the following command to load a trained model to generate features for each image (in .mat format).

./extract_features.sh <nettype> <GPU> <dataset_path> <dataset> <checkpoint_name> <feature_path> <gen_stage_features>

where <nettype> can be either dare_R or dare_D, <dataset> can be one of [MARS, Market1501, Duke, CUHK03], <feature_path> is the path to store extracted features. Toggle <gen_stage_features> to Ture to extract features from each stage.

Evaluation

Use person-re-ranking and MARS-evaluation official evaluation codes to evaluate the extracted features. Note we use mean rather than max to aggregate the image feature vectors for video sequences.

Resource-aware Person Re-ID Simulation

Use the following command to run simulations under resource-aware person re-ID scenarios. See here for more information.

./budgeted_stream/simulation.sh <dataset_path> <feature_path>
