I would like to evaluate an idea for OCR of handwritten texts (especially with mathematical contents).
Is there a dataset for OCR of handwritten texts available? It should contain images of documents, e.g. something like
It would be good (but not necessary) if the dataset contained information about the language(s) of the document and probably also the topic.
Side questions
I'm not sure how OCR algorithms are evaluated, as OCR contains multiple problems:
- Segmentation: Find single entities in the source image
- Classification: Classify the segmented images
- Placement: Find the relationship between two classified symbols (is one to the right of the other or rather the the right-top? Hence: Is it
ax
ora^x
?
I'm also not sure how such a dataset should be labeled. But for this question, I would also accept datasets which do not contain labels.
