# CASIA Character Sample Dataset
This dataset is adapted from [CASIA Online and Offline Chinese Handwriting Databases](https://nlpr.ia.ac.cn/databases/handwriting/Download.html),
but this only contains character level sample data (from the offline database). The first column is the ground truth label (single character from
GB2312 charset) and the second one is byte sequences of the decoded **PNG** files from the original [.gnt](https://nlpr.ia.ac.cn/databases/Download/DGRLRead.cpp.pdf) files.
