Hi, I ran tests wit the antiqua_modern model and the pred.txt is either empty or contains only one or two letters - anything I miss here?

Tanks Uwe

Hi Uwe, could you please append an image file? Without any further information, I can only guess:

your line image might be rotated
you're trying to read whole pages without giving calamari any information about where to find lines (eg. by using PAGE XML layout description files)

andbue commented 4 years ago

Quoting readme.md: "Currently only OCR on lines is supported." You could cut out lines using ocropus or kraken segmenters or manually create a PAGE file containing line segments using LAREX or Aletheia

exactly, the problem was that you used an entire page as input. please consider the links provided in https://github.com/Calamari-OCR/calamari/issues/169
