We’ll change directory ( cd) into the tessdata directory and use the pwd command to determine the full system path to the directory: $ cd tessdata/ The second step is to set up the TESSDATA_PREFIX environment variable to point to the directory containing the language packs. Note: Be aware that at the time of this writing, the resulting tessdata directory will be ~4.85GB, so make sure you have ample space on your hard drive. Then, we’ll simply issue the git command below to clone the repo to our local directory. We want to move to the directory that we wish to be the parent directory for what will be our local tessdata directory. The first step here is to clone Tesseract’s GitHub tessdata repository, which is located here: Set the TESSDATA_PREFIX environment variable to point to the directory containing the language packs.

Download Tesseract’s language packs manually from GitHub and install them.

Now that we have an idea of the breadth of supported languages, let’s dive in to see the most foolproof method I’ve found to configure Tesseract and unlock the power of this vast multi-language support: Note: The fourth version contains trained models for Tesseract’s legacy and newer, more accurate Long Short-Term Memory (LSTM) OCR engine. The fourth version, which we are now using supports over 100 languages and has support for characters and symbols. In the third version, support was dramatically expanded to include ideographic (symbolic) languages such as Chinese and Japanese as well as right-to-left languages such as Arabic and Hebrew. Support for French, Italian, German, Spanish, Brazilian Portuguese, and Dutch were added in the second version. The first version of Tesseract provided support for the English language only. In fact, Tesseract supports over 100 languages, including those that comprise characters and symbols, as well as right-to-left languages. Let’s take a quick look at the contents of this tessdata directory with an ls command as shown in Figure 1, below, which corresponds to the Homebrew installation on my macOS for an English language configuration.įigure 2: You can see that Tesseract OCR supports a wide array of languages.

If you are running on Ubuntu, your Tesseract language packs should be located in the directory /usr/share/tesseract-ocr//tessdata where is the version number for your Tesseract install. If you installed Tesseract on macOS via Homebrew, your Tesseract language packs should be available in /usr/local/Cellar/tesseract//share/tessdata where is the version number for your Tesseract install (you can use the tab key to autocomplete to derive the full path on your machine). We are going to review my method that gives consistent results. Technically speaking, Tesseract should already be configured to handle multiple languages, including non-English languages however, in my experience the multi-language support can be a bit temperamental.

Follow the instructions in the How to install Tesseract 4 section of that tutorial, confirm your Tesseract install, and then come back here to learn how to configure Tesseract for multiple languages.I have provided instructions for installing the Tesseract OCR engine as well as pytesseract (the Python bindings used to interface with Tesseract) in my blog post OpenCV OCR and text recognition with Tesseract.If you have not already installed Tesseract: We will break this down, step by step, to see what it looks like on both macOS and Ubuntu. In this section, we are going to configure Tesseract OCR for multiple languages. Let’s get started! Configuring Tesseract OCR for Multiple Languages Translate the OCR’d text from the given input language into English.Detect and OCR text in non-English languages.Once we have completed all of this setup, we’ll implement the Project Structure for a Python script that will: I’ll then show you how you can download multiple language packs for Tesseract and verify that it works properly - we’ll use German as an example case.įrom there, we will configure the TextBlob package, which will be used to translate from one language into another. In the first part of this tutorial you will learn how to configure the Tesseract OCR engine for multiple languages, including non-English languages.
