OCR-D-SEG-BLOCK_0001.txt

I used this dataset: https://ocr-d-repo.scc.kit.edu/api/v1/dataresources/16568d42-57be-4367-a335-4687bc84953e/data/weigel_gnothi02_1618.ocrd.zip
And the following workflow:
ocrd-anybaseocr-binarize
ocrd-anybaseocr-deskew
ocrd-anybaseocr-crop
ocrd-anybaseocr-block-segmentation with model from https://cloud.dfki.de/owncloud/index.php/s/dgACCYzytxnb7Ey/download
For the first page I got the attached result with wrong reference.
Also the metadata entry is missing.

Does 7d3fffe really fix the issue? Looks like just a change to the log call.

Now it seems to work only for cropped images! Please update documentation. (Input file group: OCR-D-IMG -> OCR-D-IMG-CROP)
