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

  3. Download CamStyle Images

    • Market-1501-Camstyle [GoogleDriver]

    • DukeMTMC-reID-CamStyle [GoogleDriver]

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

CamStyle Generation

You can generation 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
  1. 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
  1. 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
  1. 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
