You can install Tesseract and its developer tools on Ubuntu by simply running:Ĭopy the first line "deb bionic main" and paste it as shown below on the next line. If Tesseract is not available for your distribution, or you want to use a newer version than they offer, you can compile your own. Training data for obsolete Tesseract versions =< 3.02 reside in another location. Possibilities are /usr/share/tesseract-ocr/tessdata or /usr/share/tessdata or /usr/share/tesseract-ocr/4.00/tessdata. The exact directory will depend both on the type of training data, and your Linux distribution. traineddata file into a ‘tessdata’ directory. Various types of training data can be found on GitHub. If you are experimenting with OCR Engine modes, you will need to manually install language training data beyond what is available in your Linux distribution. The language traineddata packages are called ‘tesseract-ocr-langcode’ and ‘tesseract-ocr-script-scriptcode’, where langcode is three letter language code and scriptcode is four letter script code.Įxamples: tesseract-ocr-eng ( English), tesseract-ocr-ara ( Arabic), tesseract-ocr-chi-sim ( Simplified Chinese), tesseract-ocr-script-latn ( Latin Script), tesseract-ocr-script-deva ( Devanagari script), etc. Packages for over 130 languages and over 35 scripts are also available directly from the Linux distributions.
The package is generally called ‘tesseract’ or ‘tesseract-ocr’ - search your distribution’s repositories to find it.
Tesseract is available directly from many Linux distributions. There are two parts to install, the engine itself, and the traineddata for the languages. Tesseract doesn’t have a built-in GUI, but there are several available from the 3rdParty page. It can be used directly, or (for programmers) using an API to extract printed text from images.
