In the context of a work on text-lines localization in handwritten documents containing tables, we proposed to evaluate our system on a subset of cBAD (Competition on Baseline Detection, ICDAR 2017 ) dataset (track B) that contains exclusively documents with tabular structures. The dataset of the cBAD competition is available here.
Identifying which structure can be consider as a tabular structure in cBAD dataset is not always obvious. This is why we consider the following rule in order to select the documents of the subset.
A document contains a tabular structure if at least one of those two properties is verified:
• the tabular structure is materialized by vertical and horizontal rulings,
• columns of the tabular structure are materialized by vertical rulings and those columns have names.
The table subset is composed of 315 documents (51 084 text-lines).
