CorDA

Code for our paper Domain Adaptive Semantic Segmentation with Self-Supervised Depth Estimation ICCV21

Prerequisite

Please create and activate the following conda envrionment. To reproduce our results, please kindly create and use this environment.

# It may take several minutes for conda to solve the environment
conda update conda
conda env create -f environment.yml
conda activate corda 

Code was tested on a V100 with 16G Memory.

Train a CorDA model

# Train for the SYNTHIA2Cityscapes task
bash run_synthia_stereo.sh
# Train for the GTA2Cityscapes task
bash run_gta.sh

Test a trained CorDA model

bash shells/eval_syn2city.sh 
bash shells/eval_gta2city.sh

Pre-trained models are provided (Google Drive). Please put them in ./checkpoint.

• The provided SYNTHIA2Cityscapes model achieves 56.3 mIoU (16 classes) at the end of the training.
• The provided GTA2Cityscapes model achieves 57.7 mIoU (19 classes) at the end of the training.

Reported Results on SYNTHIA2Cityscapes (The reported results are based on 5 runs instead of the best run.)
