tesseract-ocrHow do I use Tesseract OCR to recognize text in an image?

Tesseract OCR (Optical Character Recognition) is a powerful open source library for recognizing text in an image. It can be used with Python, Java, and C++. Here is an example of how to use Tesseract OCR with Python:

# import the pytesseract module
import pytesseract

# Provide path to tesseract executable
pytesseract.pytesseract.tesseract_cmd = r'C:\Program Files\Tesseract-OCR\tesseract.exe'

# Read image from which text needs to be extracted
image = cv2.imread('image.png')

# Run tesseract OCR on image
text = pytesseract.image_to_string(image)

# Print recognized text
print(text)

Output example

This is a sample text.

The code above reads an image and uses Tesseract OCR to extract the text from it. Here are the parts of the code and what they do:

1. import pytesseract: imports the pytesseract module which contains functions for using Tesseract OCR.
2. pytesseract.pytesseract.tesseract_cmd = r'C:\Program Files\Tesseract-OCR\tesseract.exe': provides the path to the Tesseract executable.
3. image = cv2.imread('image.png'): reads the image from which text needs to be extracted.
4. text = pytesseract.image_to_string(image): runs Tesseract OCR on the image and extracts the text.
5. print(text): prints the recognized text.
