Tensorpacks Cascade-RCNN with FPN and Group Normalization on ResNext32xd4-50 trained on Pubtabnet for Semantic Segmentation of tables.

The model and its training code has been mainly taken from: Tensorpack .

Regarding the dataset, please check: Xu Zhong et. all. - Image-based table recognition: data, model, and evaluation.

The model has been trained on detecting cells from tables. Note, that the datasets contains tables only. Therefore, it is required to perform a table detection task before detecting cells.

The code has been adapted so that it can be used in a deepdoctection pipeline.

How this model can be used

This model can be used with the deepdoctection in a full pipeline, along with table recognition and OCR. Check the general instruction following this Get_started tutorial.

How this model was trained.

To recreate the model run on the deepdoctection framework, run:

python

>>> from deep_doctection.datasets import DatasetRegistry
>>> from deep_doctection.eval import MetricRegistry
>>> from deep_doctection.utils import get_configs_dir_path
>>> from deep_doctection.train import train_faster_rcnn

pubtabnet = DatasetRegistry.get_dataset("pubtabnet")
