Another use case I was working on today was rendering the text in a PDF file using Tesseract. I was converting the PDF to an image file first, then performing the above actions to read the text from the new image.
Here are a couple valuable resources I used to complete this little test.
- Installing Tesseract on a RHEL system – http://www.keienberg.com/install-tesseract-3-04-centos-7/ (link)
- Installing PyOCR and other image conversion tools – https://pythontips.com/2016/02/25/ocr-on-pdf-files-using-python/ (link)
Getting all the prerequisites installed was by far the hardest part on this effort.
