offline_CROHME is a tool for converting CROHME to Offline-handwritting text recognition dataset. This tool help to convert INKML file format to image and groud-truth latex.
The dataset provides more than 12 000 expressions handwritten by hundreds of writers from different countries, merging the data sets from 4 previous CROHME competitions and adding new ressources. Writers were asked to copy printed expressions from a corpus of expressions. The corpus has been designed to cover the diversity proposed by the different tasks and chosen from an existing math corpus and from expressions embedded in Wikipedia pages. Different devices have been used (different digital pen technologies, white-board input device, tablet with sensible screen), thus different scales and resolutions are used. The dataset provides only the on-line signal.
In the easy way, run below command:
python extract.pyOutput data must be stored in CROHME_processed folder. Each INKML file will be extracted to a image file and groud-truth latex string in a text file.
