PaddlePaddle == 2.3.2
torch >= 1.10.0 (for grid plot)
torchvision >= 0.11.0 (for grid plot)
sconf >= 0.2.3
lmdb >= 1.2.1
Draw all font images first including training fonts, validation fonts and your own content font. Organize directories structure as below
Font Directory
| --| font1
| --| font2
| --| ch1.png
| --| ch2.png
| --| ...
| --| ...
You also need to split all characters into train characters and val characters with unicode format and save them into json files, you can convert the utf8 format to unicode by using hex(ord(ch))[2:].upper():
train_unis: ["4E00", "4E01", ...]
val_unis: ['8E21', ...]
It is a dict you have to create by yourself before start, you can find the full CR-mapping algorithm in appendix and using the decompose dictionary of LFFont. Elements in dict also need to be converted into unicode format. Please assure keys of CR mapping contain both of train_unis and val_unis.
{content1: [ref1, ref2, ref3, ...], content2: [ref1, ref2, ref3, ...], ...}
example(in utf-8 format):
{连: [转, 还], 剧: [呢, 别, 卖], 愫: [累, 快, 请], ...}
PS: You have to make sure the number of refereces of all contents be same for purpose of batch training.
e.g. 连: [转, 转, 还]
python3 ./build_dataset/build_meta4train.py
--saving_dir ./results/your_task_name/
--content_font path\to\content
--train_font_dir path\to\training_font
--val_font_dir path\to\validation_font
--seen_unis_file path\to\train_unis.json
--unseen_unis_file path\to\val_unis.json
You can modify the configuration in the file cfgs/custom.yaml
- work_dir: the root directory for saved results. (keep same with the
saving_dirabove) - data_path: path to data lmdb environment. (
saving_dir/lmdb) - data_meta: path to train meta file. (
saving_dir/meta) - content_font: the name of font you want to use as source font.
- content_reference_json: the json file which stores content_referece mapping.
- other values are hyperparameters for training.
python3 train.py
task_name
cfgs/custom.yaml
--resume \path\to\your\pretrain_model.pdparams
python3 inference.py ./cfgs/custom.yaml
--weight path\to\saved_weight.pdparams
--content_font path\to\content
--img_path path\to\reference
--saving_root path\to\saving_folder
Our code is modified based on the LFFont.
