# Learning to Adapt Structured Output Space for Semantic Segmentation
Pytorch implementation of our method for adapting semantic segmentation from the synthetic dataset (source domain) to the real dataset (target domain). Based on this implementation, our result is ranked 3rd in the [VisDA Challenge](http://ai.bu.edu/visda-2017/).

## Example Results
## Quantitative Reuslts
## Installation
* Install PyTorch from http://pytorch.org with Python 2 and CUDA 8.0
* **NEW** Add the LS-GAN objective to improve the performance
- Usage: add `--gan LS` option during training (see below for more details)
* PyTorch 0.4 with Python 3 and CUDA 8.0
- Usage: replace the training and evaluation codes with the ones in the `pytorch_0.4` folder
- Update: tensorboard is provided by adding `--tensorboard` in the command
- Note: the single-level model works as expected, while the multi-level model requires smaller weights, e.g., `--lambda-adv-target1 0.00005 --lambda-adv-target2 0.0005`. We will investigate this issue soon.
* Clone this repo
```
git clone https://github.com/wasidennis/AdaptSegNet
cd AdaptSegNet
```
## Dataset
* Download the [GTA5 Dataset](https://download.visinf.tu-darmstadt.de/data/from_games/) as the source domain, and put it in the `data/GTA5` folder
* Download the [Cityscapes Dataset](https://www.cityscapes-dataset.com/) as the target domain, and put it in the `data/Cityscapes` folder
## Pre-trained Models
* Please find our-pretrained models using ResNet-101 on three benchmark settings [here](https://www.dropbox.com/s/gpzm15ipyt01mis/DA_Seg_models.zip?dl=0)
* They include baselines (without adaptation and with feature adaptation) and our models (single-level and multi-level)
## Testing
* **NEW** Update results using LS-GAN and using [Synscapes](https://7dlabs.com/synscapes-overview) as the source domain
- Performance: check the appendix of the updated [arXiv paper](https://arxiv.org/abs/1802.10349) (updated on 10/17/2019)
- [Pre-trained models](https://www.dropbox.com/s/sif9cd6ad4s9y5d/AdaptSegNet_LSGAN_models.zip?dl=0)
* Download the pre-trained multi-level [GTA5-to-Cityscapes model](http://vllab.ucmerced.edu/ytsai/CVPR18/GTA2Cityscapes_multi-ed35151c.pth) and put it in the `model` folder
* Test the model and results will be saved in the `result` folder
```
python evaluate_cityscapes.py --restore-from ./model/GTA2Cityscapes_multi-ed35151c.pth
```
* Or, test the VGG-16 based model [Model Link](http://vllab.ucmerced.edu/ytsai/CVPR18/GTA2Cityscapes_vgg-ac4ac9f6.pth)
```
python evaluate_cityscapes.py --model DeeplabVGG --restore-from ./model/GTA2Cityscapes_vgg-ac4ac9f6.pth
```
* Compute the IoU on Cityscapes (thanks to the code from [VisDA Challenge](http://ai.bu.edu/visda-2017/))
```
python compute_iou.py ./data/Cityscapes/data/gtFine/val result/cityscapes
```
## Training Examples
* **NEW** Train the GTA5-to-Cityscapes model (single-level with LS-GAN)
```
python train_gta2cityscapes_multi.py --snapshot-dir ./snapshots/GTA2Cityscapes_single_lsgan \
--lambda-seg 0.0 \
--lambda-adv-target1 0.0 --lambda-adv-target2 0.01 \
--gan LS
```
* Train the GTA5-to-Cityscapes model (multi-level)
```
python train_gta2cityscapes_multi.py --snapshot-dir ./snapshots/GTA2Cityscapes_multi \
--lambda-seg 0.1 \
--lambda-adv-target1 0.0002 --lambda-adv-target2 0.001
```
* Train the GTA5-to-Cityscapes model (single-level)
```
python train_gta2cityscapes_multi.py --snapshot-dir ./snapshots/GTA2Cityscapes_single \
--lambda-seg 0.0 \
--lambda-adv-target1 0.0 --lambda-adv-target2 0.001
```
