SynthTIGER 馃惎 : Synthetic Text Image Generator
Synthetic Text Image Generator for OCR Model | Paper | Documentation | Datasets
The documentation is available at https://clovaai.github.io/synthtiger/. You can check API reference in this documentation. InstallationSynthTIGER requires python>=3.6 and libraqm. To install SynthTIGER from PyPI: $ pip install synthtigerIf you see a dependency error when you install or run SynthTIGER, install dependencies. Usage # Set environment variable (for macOS) $ export OBJC_DISABLE_INITIALIZE_FORK_SAFETY=YES usage: synthtiger [-h] [-o DIR] [-c NUM] [-w NUM] [-s NUM] [-v] SCRIPT NAME [CONFIG] positional arguments: SCRIPT Script file path. NAME Template class name. CONFIG Config file path. optional arguments: -h, --help show this help message and exit -o DIR, --output DIR Directory path to save data. -c NUM, --count NUM Number of output data. [default: 100] -w NUM, --worker NUM Number of workers. If 0, It generates data in the main process. [default: 0] -s NUM, --seed NUM Random seed. [default: None] -v, --verbose Print error messages while generating data. Examples SynthTIGER text images # horizontal synthtiger -o results -w 4 -v examples/synthtiger/template.py SynthTiger examples/synthtiger/config_horizontal.yaml # vertical synthtiger -o results -w 4 -v examples/synthtiger/template.py SynthTiger examples/synthtiger/config_vertical.yaml
Prepare corpus txt format, line by line (example). Prepare fonts See font customization for more details. Edit corpus path and font path in config file (example) Run synthtiger Font customizationPrepare fonts ttf/otf format (example). Extract renderable charsets python tools/extract_font_charset.py -w 4 fonts/This script extracts renderable charsets for all font files (example). Text files are generated in the input path with the same names as the fonts. Edit font path in config file (example) Run synthtiger Colormap customizationPrepare images jpg/jpeg/png/bmp format. Create colormaps python tools/create_colormap.py --max_k 3 -w 4 images/ colormap.txtThis script creates colormaps for all image files (example). Edit colormap path in config file (example) Run synthtiger Template customizationYou can implement custom templates by inheriting the base template. from synthtiger import templates class MyTemplate(templates.Template): def __init__(self, config=None): # initialize template. def generate(self): # generate data. def init_save(self, root): # initialize something before save. def save(self, root, data, idx): # save data to specific path. def end_save(self, root): # finalize something after save. DatasetsSynthTIGER is available for download at google drive. Dataset was split into several smaller files. Please download all files and run following command. # for Linux, macOS cat synthtiger_v1.0.zip.* > synthtiger_v1.0.zip # for Windows copy /b synthtiger_v1.0.zip.* synthtiger_v1.0.zipsynthtiger_v1.0.zip (36G) (md5: 5b5365f4fe15de24e403a9256079be70) Original paper version. Used MJ and ST label.synthtiger_v1.1.zip (38G) (md5: b2757a7e2b5040b14ed64c473533b592) Used MJ and ST lexicon instead of MJ and ST label. resources/corpus/mjsynth.txt resources/corpus/synthtext.txt Fixed a bug that applies transformation twice on curved text. Fixed a bug that incorrectly converts grayscale to RGB.
