Nkocr

This is a module to make specifics OCRs at food products and nutricional tables.

As a prerequisite of this project, we have the tesseract library which can be found in more detail at

https://github.com/tesseract-ocr/tesseract

Installation of prerequisite

The installation of tesseract on the Linux system can be done in a few commands:

$ sudo apt install tesseract-ocr
$ sudo apt install libtesseract-dev

And the same goes for macOS. There is a variation between MacPorts and Homebrew, but in this post I will only quote the version of Homebrew:

$ brew install tesseract

After performing the tesseract installation, it is possible to perform OCR in just one command, thus already extracting some words from the image.

The default language is English, depending on the text, it will not be possible to capture the word/phrase. If you want to work with another language, you need to make some additional installations. (https://github.com/tesseract-ocr/tesseract/wiki#other-languages)
