Pretrained Model

Pretrained models for CDD, LEVIR-CD and WHU-CD are available. You can download them from the following link. [Baiduyun] the password is yudl. [GoogleDrive]

Test

Before test, please download datasets and pretrained models. Revise the data-path in constants.py to your path. Copy pretrained models to folder './dataset_name/outputs/best_weights', and run the following command:

cd CSA-CDGAN_ROOT
python make_dataset.py
python test.py

make_dataset.py can generate .txt files for training, validation and test. Not that the dataset structure should be the same as following:

Custom dataset
|--train
  |--file1
    |--t0.jpg, t1.jpt, label.jpg
  |--file2
    |--t0.jpg, t1.jpt, label.jpg
  ...
|--test
  |--file1
    |--t0.jpg, t1.jpt, label.jpg
  |--file2
    |--t0.jpg, t1.jpt, label.jpg
  ...
|--validation
  |--file1
    |--t0.jpg, t1.jpt, label.jpg
  |--file2
    |--t0.jpg, t1.jpt, label.jpg
  ...

Training

cd CSA-CDGAN_ROOT
python make_dataset.py
python -m visdom.server
python train.py
