| | [TextOCR](https://textvqa.org/textocr/) | real | Annotations for a subset of Open Images. Processed with [`textocr_converter.py`](tools/textocr_converter.py). A _horizontal_ version can be generated by passing `--rectify_pose`. | | |
| \[1\] Case-sensitive annotations from [Long and Yao](https://github.com/Jyouhou/Case-Sensitive-Scene-Text-Recognition-Datasets) + [our corrections](https://github.com/baudm/Case-Sensitive-Scene-Text-Recognition-Datasets). Processed with [case_sensitive_str_datasets_converter.py](tools/case_sensitive_str_datasets_converter.py)<br/> | |
| \[2\] Archives used as-is from [Baek et al.](https://github.com/ku21fan/STR-Fewer-Labels/blob/main/data.md) They are included in the dataset release for convenience. Please refer to their work for more info about the datasets. | |
| The preprocessed archives are available here: [val + test + most of train](https://drive.google.com/drive/folders/1NYuoi7dfJVgo-zUJogh8UQZgIMpLviOE), [TextOCR + OpenVINO](https://drive.google.com/drive/folders/1D9z_YJVa6f-O0juni-yG5jcwnhvYw-qC) | |
