We use various synthetic and real datasets. More info is in Appendix F of the supplementary material. Some preprocessing scripts are included in tools/.

Dataset	Type	Remarks
MJSynth	synthetic	Case-sensitive annotations were extracted from the image filenames
SynthText	synthetic	Processed with crop_by_word_bb_syn90k.py
IC13	real	Three archives: 857, 1015, 1095 (full)
IC15	real	Two archives: 1811, 2077 (full)
CUTE80	real	[1]
IIIT5k	real	[1]
SVT	real	[1]
SVTP	real	[1]
ArT	real	[2]
LSVT	real	[2]
MLT19	real	[2]
RCTW17	real	[2]
ReCTS	real	[2]
Uber-Text	real	[2]
COCO-Text v1.4	real	Processed with coco_text_converter.py
COCO-Text v2.0	real	Processed with coco_2_converter.py
OpenVINO	real	Annotations for a subset of Open Images. Processed with openvino_converter.py.
TextOCR	real	Annotations for a subset of Open Images. Processed with textocr_converter.py. A horizontal version can be generated by passing --rectify_pose.

[1] Case-sensitive annotations from Long and Yao + our corrections. Processed with case_sensitive_str_datasets_converter.py
[2] Archives used as-is from Baek et al. 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, TextOCR + OpenVINO

The expected filesystem structure is as follows:
