Dependencies

• cuda 10.2
• pytorch >= 1.3
• opencv
• gdal

Running the implementation

After installing all of the required dependencies above you can download the pretrained weights from here.

Unzip the archive and place saved_models_gan folder in the main projectRegularization directory.

Please note that the polygonization step is not yet available!

Evaluation

Modify variables.py accordingly, then run the prediction issuing the command

python regularize.py

Training

Modify variables.py accordingly, then run the training issuing the command
