The pytorch implementation of paper "Collaborative Training between Region Proposal Localization and Classification for Domain Adaptive Object Detection" in ECCV2020.

The project is based on this repository. Please follow the instructions to setup the enviroment. We used Pytorch 0.4.0 and torchvision 0.2.2 for this project.

• Cityscapes Please refer to this website to download the data. The training set includes 2964 images.
• FoggyCityscapes Please refer to this website to download the data.

Unzip both dataset in ./data, then run boxes_for_cityscapes.py to convert the annotation format.

1. Pretrain with source data.

   CUDA_VISIBLE_DEVICES=${gpu_id} python cityscapes_pretrain.py

2. Domain adaptation with target data.

   CUDA_VISIBLE_DEVICES=${gpu_id} python cityscapes_to_foggycityscapes_da.py

3. Test with target data.

   CUDA_VISIBLE_DEVICES=${gpu_id} python cityscapes_to_foggycityscapes_da_test.py --checksession ${session_id} --checkepoch ${epoch_num} --checkpoint ${point_num}

The pretrained model will be released soon.
