tesseract-ocrHow do I set up Tesseract OCR?


Setting up Tesseract OCR is quite simple.

  1. Install the Tesseract OCR library on your system. This can be done in various ways depending on your operating system. For example, on Ubuntu you can use the command sudo apt-get install tesseract-ocr to install the library.

  2. Once the library is installed, you can use the Python-Tesseract wrapper to access the Tesseract OCR API. To install it, use the command pip install pytesseract.

  3. Once the wrapper is installed, you can use it in your Python code. For example, the following code will read an image file and output the text detected by the OCR engine:

import pytesseract
from PIL import Image

image = Image.open('image.png')
text = pytesseract.image_to_string(image)
print(text)

Output example

This is an example of text detected by Tesseract OCR.
  1. To further customize the Tesseract OCR engine, you can pass parameters to the image_to_string function. For example, you can specify the language of the text to be detected using the lang parameter:
import pytesseract
from PIL import Image

image = Image.open('image.png')
text = pytesseract.image_to_string(image, lang='deu')
print(text)

Output example

Dies ist ein Beispiel für Text, der von Tesseract OCR erkannt wird.
  1. To learn more about the Tesseract OCR library and the Python-Tesseract wrapper, you can check out the official documentation here and here.

  2. You can also find many tutorials and examples online. For example, this tutorial provides a good introduction to using Tesseract OCR with Python.

  3. Finally, you can also use the Tesseract OCR library directly, without the Python-Tesseract wrapper. For more information on this, you can check out the official documentation here.
