Abstract
Automatic generation of artistic glyph images is a challenging task that attracts many research interests. Previous methods either are specifically designed for shape synthesis or focus on texture transfer. In this paper, we propose a novel model, AGIS-Net, to transfer both shape and texture styles in one-stage with only a few stylized samples. To achieve this goal, we first disentangle the representations for content and style by using two encoders, ensuring the multi-content and multi-style generation. Then we utilize two collaboratively working decoders to generate the glyph shape image and its texture image simultaneously. In addition, we introduce a local texture refinement loss to further improve the quality of the synthesized textures. In this manner, our one-stage model is much more efficient and effective than other multi-stage stacked methods. We also propose a large-scale dataset with Chinese glyph images in various shape and texture styles, rendered from 35 professional-designed artistic fonts with 7,326 characters and 2,460 synthetic artistic fonts with 639 characters, to validate the effectiveness and extendability of our method. Extensive experiments on both English and Chinese artistic glyph image datasets demonstrate the superiority of our model in generating high-quality stylized glyph images against other state-of-the-art methods.

Datasets
The datasets server is down, you can download the datasets from PKU Disk, Dropbox or MEGA. Download the datasets using the following script, four datasets and the raw average font style glyph image are available.
It may take a while, please be patient
bash ./datasets/download_dataset.sh DATASET_NAME
base_gray_color
English synthesized gradient glyph image dataset, proposed by MC-GAN.base_gray_texture
English artistic glyph image dataset, proposed by MC-GAN.skeleton_gray_color
Chinese synthesized gradient glyph image dataset by us.skeleton_gray_texture
Chinese artistic glyph image dataset proposed by us.average_skeleton
Raw Chinese avgerage font style (skeleton) glyph image dataset proposed by us.
Please refer to the data for more details about our datasets and how to prepare your own datasets.
Model Training
-
To train a model, download the training images (e.g., English artistic glyph transfer)
bash ./datasets/download_dataset.sh base_gray_color bash ./datasets/download_dataset.sh base_gray_texture
-
Train a model:
-
Start the Visdom Visualizer
python -m visdom.server -port PORT
PORT is specified in
train.sh
-
Pretrain on synthesized gradient glyph image dataset
bash ./scripts/train.sh base_gray_color GPU_ID
GPU_ID indicates which GPU to use.
-
Fineture on artistic glyph image dataset
bash ./scripts/train.sh base_gray_texture GPU_ID DATA_ID FEW_SIZE
DATA_ID indicates which artistic font is fine-tuned.
FEW_SIZE indicates the size of few-shot set.It will raise an error saying:
FileNodeFoundError: [Error 2] No such file or directory: 'chechpoints/base_gray_texture/base_gray_texture_DATA_ID_TIME/latest_net_G.pth
Copy the pretrained model to above path
cp chechpoints/base_gray_color/base_gray_color_TIME/latest_net_* chechpoints/base_gray_texture/base_gray_texture_DATA_ID_TIME/
And start train again. It will works well.
-
Model Testing
-
To test a model, copy the trained model from
checkpoint
topretrained_models
folder (e.g., English artistic glyph transfer)cp chechpoints/base_gray_color/base_gray_texture_DATA_ID_TIME/latest_net_* pretrained_models/base_gray_texture_DATA_ID/
-
Test a model
bash ./scripts/test_base_gray_texture.sh GPU_ID DATA_ID
