Prerequisites

  • Linux, macOS or Windows
  • Python 3.7
  • CPU or NVIDIA GPU + CUDA CuDNN

Getting Started

Downloading Datasets

Please refer to datasets.md for details.

Installation

  • Clone this repo:
git clone https://github.com/giddyyupp/AdvSegLoss.git
cd AdvSegLoss
conda install pytorch=1.7.0 torchvision cudatoolkit=11.0 -c pytorch

Or install all deps using pip:

pip install -r requirements.txt

Download panoptic segmentation model from detectron model zoo, and put it under models/segmentation/detectron2.

After installations completed, you need to change two files in detectron2. These changes are shared in the ./models/segmentation/detectron2/changes.diff file.

AdvSegLoss train/test

  • Download a dataset (e.g. bedroom) and generate edge maps:

Follow steps in the datasets.md to download, and prepare datasets.

  • Train a model with unpaired training:
#!./scripts/train_advsegloss.sh
python train.py --checkpoints_dir ./checkpoints --name ade20k_hed_advsegloss_both --dataroot ./datasets/ade20k_hed --model cycle_gan --segmentation --segmentation_output "both" --direction "AtoB" --dataset_mode "unaligned"
  • To view training results and loss plots, run python -m visdom.server and click the URL http://localhost:8097. To see more intermediate results, check out ./checkpoints/maps_cyclegan/web/index.html
  • Test the model:
#!./scripts/test_advsegloss.sh
python test.py --checkpoints_dir ./checkpoints --name ade20k_hed_advsegloss_both --dataroot ./datasets/ade20k_hed --model test --segmentation --segmentation_output "both" --direction "AtoB" --dataset_mode "unaligned"

The test results will be saved to a html file here: ./results/ade20k_hed_advsegloss_both/latest_test/index.html.

You can find more scripts at scripts directory.

Apply a pre-trained model

  • You can download pretrained models using following link

Put a pretrained model under ./checkpoints/{name}_pretrained/100_net_G.pth.

  • Then generate the results using
python test.py --dataroot datasets/ade20k_hed/testB --name {name}_pretrained --model test --segmentation --segmentation_output "both" --direction "AtoB" --dataset_mode "unaligned"

The results will be saved at ./results/. Use --results_dir {directory_path_to_save_result} to specify the results directory.

Training/Test Tips

Best practice for training and testing your models.
