tesseract-ocrHow do I use tesseract OCR to generate HTML output?


Tesseract OCR is an open source Optical Character Recognition (OCR) engine developed by Google. It can be used to generate HTML output from scanned documents.

To use Tesseract OCR to generate HTML output, you need to install the Tesseract OCR engine and the Tesseract OCR command line tools.

Once the installation is complete, you can use the following command to generate HTML output from a scanned document:
