![]() ![]() Note that as yet there are very few 3rdParty Tesseract OCR projects being developed for Mac (with the only one being Tesseract macOS.md), although there are several online OCR services that can be used on Mac that may use Tesseract as their OCR engine.Īlso, it is free software, so if you want to pitch in and help, please do! See the 3rdParty page for a sample of what has been done with it. It has a fully featured API, and can be compiled for a variety of targets including Android and the iPhone. Tesseract can also be used in your own project, under the terms of the Apache License 2.0. It can also be trained to support other languages and scripts for more details see TrainingTesseract. Tesseract has been trained for many languages, check for your language in the Tessdata repository. More information about the various options is available in the Tesseract manpage. Released version >= 3.02 of tesseract-ocr are part of Cygwin To access tesseract-OCR from any location you may have to add the directory where the tesseract-OCR binaries are located to the Path variables, probably C:\Program Files\Tesseract-OCR.Įxperts can also get binaries build with Visual Studio from the build artifacts of the Appveyor Continuous Integration. traineddata file into the ‘tessdata’ directory, probably C:\Program Files\Tesseract-OCR\tessdata. If you want to use another language, download the appropriate training data, Both 32-bit and 64-bit installers are available.Īn installer for the OLD version 3.02 is available for Windows from our download page. Installer for Windows for Tesseract 3.05, Tesseract 4 and Tesseract 5 are available from Tesseract at UB Mannheim. ![]() usr/local/Cellar/tesseract/3.05.02/share/tessdata/. The tesseract directory can then be found using brew info tesseract,Į.g. tesseract*.AppImage -l eng page.tif page.txtįor distributions that are supported by snapd you may also run the following command to install the tesseract built binaries( Don’t have snapd installed?): Open your terminal application, if not already open.See Installation on OpenSuse page for detailed instructions. RHEL/CentOS/Scientific Linux, Fedora, openSUSE packages If you are using a different release of ubuntu, then replace bionic with the respective release name. 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. Tesseract is an open source text recognition (OCR) Engine, available under the Apache 2.0 license.
