Camera Style Adaptation for Person Re-identification

================================================================

Code for Camera Style Adaptation for Person Re-identification (CVPR 2018).

Preparation

Requirements: Python=3.6 and Pytorch>=0.3.0

1. Install Pytorch

2. Download dataset

   • Market-1501 [BaiduYun] [GoogleDriver]

   • DukeMTMC-reID [BaiduYun] (password: chu1) [GoogleDriver]

   • Move them to 'CamStyle/data/market (or duke)'

3. Download CamStyle Images

   • Market-1501-Camstyle [GoogleDriver] [BaiduYun] [Password:tfa2]

   • DukeMTMC-reID-CamStyle [GoogleDriver] [BaiduYun] [Password:kibf]

   • Move them to 'CamStyle/data/market (or duke)/bounding_box_train_camstyle'

CamStyle Generation

You can generate CamStyle imgaes with CycleGAN-for-CamStyle

Training and test re-ID model

1. IDE

# For Market-1501
python main.py -d market --logs-dir logs/market-ide
# For Duke
python main.py -d duke --logs-dir logs/duke-ide

2. IDE + CamStyle

# For Market-1501
python main.py -d market --logs-dir logs/market-ide-camstyle --camstyle 46
# For Duke
python main.py -d duke --logs-dir logs/duke-ide--camstyle --camstyle 46

3. IDE + CamStyle + Random Erasing[4]

# For Market-1501
python main.py -d market --logs-dir logs/market-ide-camstyle-re --camstyle 46 --re 0.5
# For Duke
python main.py -d duke --logs-dir logs/duke-ide--camstyle-re --camstyle 46 --re 0.5

4. IDE + CamStyle + Random Erasing[4] + re-ranking[3]

# For Market-1501
python main.py -d market --logs-dir logs/market-ide-camstyle-re --camstyle 46 --re 0.5 --rerank
# For Duke
python main.py -d duke --logs-dir logs/duke-ide--camstyle-re --camstyle 46 --re 0.5 --rerank
