Re: [tesseract-ocr] Problem with using two trained.data files in combination for a better result.

i think this could be if your new traineddats is not trained to as high a accuracy level as the eng traineddata. You can setup a debug log to verify this. see https://github.com/tesseract-ocr/tesseract/issues/1275#issuecomment-360367865 for details On Wed, Aug 8, 2018 at 6:04 PM wrote: > i'm tr

Re: [tesseract-ocr] Problem with using two trained.data files in combination for a better result.

I do not know about the internal algorithms used by tesseract. If you are having accuracy issues with certain letters and digits, I will suggest that you fine-tune for impact using the images or similar font. Please see wiki page on training 4.0 for the command - look for fine tuning for new fon
