Example Results

Quantitative Results

Prerequisite

• Pytorch 0.3.1
• Nvidia GPU with at least 16 GB memory

Installation

git clone https://github.com/a514514772/DISE-Domain-Invariant-Structure-Extraction.git

Datasets

1. Download the GTA5 Dataset as the source domain and unzip it to /data
2. Download the Cityscapes Dataset as the target domain and unzip it to /data

The structure of /data may look like this:

├── data
    ├── Cityscapes
    │   ├── gtFine
    │   └── leftImg8bit
    ├── GTA5
        ├── images
        └── labels

Usage

Pretrained Weights

Google drive

Example Training Script: GTA5 to Cityscapes

python train_dise_gta2city.py --gta5_data_path /data/GTA5 --city_data_path /data/Cityscapes

Example Testing Script:

Note that, to test performance on the testing set, we provide scripts to generate 1024x2048 outputs which are compatible with the testing server.

python evaluate.py ./weights --city_data_path /data/Cityscapes
