Run

Download the testing-data.zip, and unzip. The _train folder is expected to be next to the _gen folder.

Pre-Trained models

If you want just quickly test the network, here are some pre-trained-models.zip. Unzip, and follow with the Generate step. Be sure to set the correct --checkpoint path when calling generate.py, e.g., _pre-trained-models/Zuzka2/model_00020.pth.

Train

To train the network, run the train.py See the example command below:

train.py --config "_config/reference_P.yaml" 
		 --data_root "Zuzka2_train" 
		 --log_interval 1000 
		 --log_folder logs_reference_P

Every 1000 (log_interval) epochs, train.py saves the current generator to logs_reference_P (log_folder), and it validates/runs the generator on _gen data - the result is saved in Zuzka2_gen/res__P

Generate

To generate the results, run generate.py.

generate.py --checkpoint "Zuzka2_train/logs_reference_P/model_00020.pth" 
	    --data_root "Zuzka2_gen"
	    --dir_input "input_filtered"
	    --outdir "Zuzka2_gen/res_00020" 
	    --device "cuda:0"

Installation

Tested on Windows 10, Python 3.7.8, CUDA 10.2. With the following python packages:

numpy                  1.19.1
opencv-python          4.4.0.40
Pillow                 7.2.0
PyYAML                 5.3.1
scikit-image           0.17.2
scipy                  1.5.2
tensorflow 	       1.15.3 (tensorflow is used only in the logger.py, I will remove this not-necessary dependency soon)
torch                  1.6.0
torchvision            0.7.0

TODO

• Add code for "interactive" usedcase as shown in the paper.
• Remove the dependency on tensorflow.
