Requirements

This code is built on top of the Cycle-GAN source code.

The required Python packages are:

  • torch>=0.4.1
  • torchvision>=0.2.1
  • dominate>=2.3.1
  • visdom>=0.1.8.3
  • faiss

Pre-trained Models

Download pre-trained models and place them under the checkpoint folder. For example, when downloading the monet2photo checkpoints, place them under the folder ./checkpoints/monet2photo/.

Test

Run python test.py using the following arguments:

Argument Possible values
--dataroot Dataset root folder containing the testA directory
--name monet2photo, landscape2photo, portrait2photo
--num_test Number of test samples

For example, to reproduce the results of our model for the first 100 test samples of the landscape2photo setting, use:

python test.py --dataroot ./datasets/landscape2photo --name landscape2photo --num_test 100

Training

Note: for simplicity, the released training code does not include the regular update of semantic masks from the generated images. In this code, original painting masks are kept fixed.

To run the training code, download the following zip folder containing RGB patches of real landscapes, FAISS indexes and masks from Monet and landscape paintings:

Place it under the root code folder (i.e. ./data_for_patch_retrieval).

Run python train.py using the following arguments:

Argument Possible values
--dataroot Dataset root folder containing the trainA and trainB directories
--name Name of the experiment. It decides where to store samples and models
--no_flip Since artistic masks are fixed, we do not random flip images during training
--patch_size_1 Height and width of the first scale patches
--stride_1 Stride of the first scale patches
--patch_size_2 Height and width of the second scale patches
--stride_2 Stride of the second scale patches
--patch_size_3 Height and width of the third scale patches
--stride_3 Stride of the third scale patches
--which_mem_bank ./data_for_patch_retrieval
--artistic_masks_dir masks_of_artistic_images_monet, masks_of_artistic_images_landscape
--preload_mem_patches If specified, load all RGB patches in memory
--preload_indexes If specified, load all FAISS indexes in memory
  • Required RAM for both RGB patches and FAISS indexes: ~40 GB.

  • Specify only --patch_size_1 and --stride_1 to run the single-scale version.

For example, to train the model on the landscape2photo setting, use:

python train.py --dataroot ./datasets/landscape2photo --name landscape2photo --no_dropout --display_id 0 --no_flip --niter_decay 100 --no_flip --patch_size_1 16 --stride_1 6 --patch_size_2 8 --stride_2 5 --patch_size_3 --stride_3 4 --which_mem_bank ./data_for_patch_retrieval --artistic_masks_dir masks_of_artistic_images_landscape --preload_mem_patches --preload_indexes
