Download the dataset. Create two empty directories ./datasets/TRAIN_DATA/trainA and ./datasets/TRAIN_DATA/trainB.
Put non-pixel art images in ./datasets/TRAIN_DATA/trainA and put multi-cell pixel arts in ./datasets/TRAIN_DATA/trainB.
Run the following command to train:
python train.py --gpu_ids 0 --batch_size 2 --preprocess none --dataroot ./datasets/TRAIN_DATA/ --name YOUR_MODEL_NAME
The checkpoints and logs will be saved in ./checkpoints/YOUR_MODEL_NAME.
Create empty directory ./dataset/TEST_DATA/Input.
Put test images in ./dataset/TEST_DATA/Input, and run python prepare_data.py to prepare data.
Run the following command to test:
python test.py --gpu_ids 0 --batch_size 1 --preprocess none --num_test 4 --epoch WHICH_EPOCH --dataroot ./datasets/TEST_DATA/ --name YOUR_MODEL_NAME
The result will be saved in ./result/YOUR_MODEL_NAME.
