White-box-Cartoonization (PyTorch)

Unofficial PyTorch implementation of White-box-Cartoonization. We followed the original Tensorflow training implementation from the paper author (Xinrui Wang).

Key difference from Tensorflow implementation:

• Its PyTorch.
• We used PyTorchVGG19 instead of CaffeVGG16 model, which has a different range of input/output and std/mean.

Our Results

• Images:

Image inference Demo

I have only trained a model on scenery images only.

python3 image_infer_demo.py -w weights/sceneryonly.pth.tar

Should start a demo like this:

To start training

0. Read https://vinesmsuic.github.io/i2i-wbcartoonization/ to understand the implementation
1. Prepare the photo and cartoon data
2. Get the pre-trained VGG19 weight and put it in the root folder : https://download.pytorch.org/models/vgg19-dcbb9e9d.pth
3. Edit config.py
4. Training (if you need to use the parser, type python train.py -h to see existing options

python train.py

• The training consist of initialization phase and training phase.
• Wait for a long time and see the results at results folder

  --save_img_freq SAVE_IMG_FREQ
                        saving training image each N steps. default value:1000
  --epochs EPOCHS       default value:200
  --lambda_surface LAMBDA_SURFACE

Test

usage: test.py [-h] [--dataroot DATAROOT] [--weight_path WEIGHT_PATH] [--dest_folder DEST_FOLDER] [--sample_size SAMPLE_SIZE] [--shuffle] [--concat_img]
               [--no_post_processing]

test.py: Model testing script of White-box Cartoonization. For inference, please refer to inference.py

optional arguments:
  -h, --help            show this help message and exit
  --dataroot DATAROOT   path to image data test folder. default path:data\val\photo
  --weight_path WEIGHT_PATH
                        path to model weight file. default path:checkpoints\project_name\i_gen.pth.tar
  --dest_folder DEST_FOLDER
                        path to destination folder for saving images. default path:results\project_name\test
  --sample_size SAMPLE_SIZE
                        only inference certain number of images. default=50.
  --shuffle             shuffle test data
  --concat_img          concat input and output images instead of separated save files
  --no_post_processing  disable post_processing (not recommended). This will probably cause output to have terrible noise

Inference (Support Video)

usage: inference.py [-h] -s SOURCE -w WEIGHT_PATH [--batch_size BATCH_SIZE] --dest_folder DEST_FOLDER
                    [--suffix SUFFIX]

  -w WEIGHT_PATH, --weight_path WEIGHT_PATH
                        path to model weight file.
  --batch_size BATCH_SIZE
                        batch size for video inference. default size:32
  --dest_folder DEST_FOLDER
                        Destination folder path for saving results.
