This page is for a paper which is to appear in CVPR2018 [1]. You can also find project page for the paper in [2].

Here is the example of our results in watercolor images.

• Python 3.5+
• Chainer 3.0+
• ChainerCV 0.8+
• Cupy 2.0+
• OpenCV 3+
• Matplotlib

Please install all the libraries. We recommend pip install -r requirements.txt.

Please go to both models and datasets directory and follow the instructions.

For more details about arguments, please refer to -h option or the actual codes.

python demo.py input/watercolor_142090457.jpg output.jpg --gpu 0 --load models/watercolor_dt_pl_ssd300

python eval_model.py --root datasets/clipart --data_type clipart --det_type ssd300 --gpu 0 --load models/clipart_dt_pl_ssd300

python train_model.py --root datasets/clipart --subset train --result result --det_type ssd300 --data_type clipart --gpu 0

Rest of this section shows examples for experiments in clipart dataset.

1. (Preprocess): please follow instructions in ./datasets/README.md to create folders.

2. Domain transfer (DT) step

   1. python train_model.py --root datasets/dt_clipart/VOC2007 --root datasets/dt_clipart/VOC2012 --subset train --result result/dt_clipart --det_type ssd300 --data_type clipart --gpu 0 --max_iter 500

   We provide models obtained in this step at ./models.

3. Pseudo labeling (PL) step

   1. python pseudo_label.py --root datasets/clipart --data_type clipart --det_type ssd300 --gpu 0 --load models/clipart_dt_ssd300 --result datasets/dt_pl_clipart
   2. python train_model.py --root datasets/dt_pl_clipart --subset train --result result/dt_pl_clipart --det_type ssd300 --data_type clipart --gpu 0 --load models/clipart_dt_ssd300 --eval_root datasets/clipart
