Text-line detection & extracion [segmenting pages into lines] about calamari HOT 7 CLOSED

@madisonmay You can also use kraken's segmentation which handily produces JSON of bounding boxes (https://github.com/mittagessen/kraken/blob/master/docs/advanced.rst#page-segmentation-and-script-detection). Ocropy has two PR (ocropus-archive/DUP-ocropy#281 and ocropus-archive/DUP-ocropy#283) which also provided such coordinates JSON.

• Unfortunately there are no updates on the FCN, yet
• CPU will be used by default for training and prediction if no valid GPU is available

We are still hoping that you release a text line detection and extraction implementation in calamari in the future.
Thank you.

@ChWick Is there any tool available at GitHub that you recommend using for training text-line detection and extraction?

@mrocr Maybe the line segmenter of T. Breuel https://github.com/NVlabs/ocroseg is what you are looking for.

The developer of Kraken has noted to me that ocroseg doesn't converge, even when using the same uw3 dataset that T. Breuel used.

Hey there @ChWick. The README states that you intend to eventually move the ocropy line segmentation step into calamari. Is there a branch where this work is in progress that I could potentially build off of?
