2. EasyOCR
Tesseract is undoubtedly the most popular and widely used OCR library in the Python ecosystem. Originally developed by HP and now maintained by Google, Tesseract provides high-quality OCR capabilities for over 100 languages.
import pyocr
from PIL import Image
# Choose the OCR tool (Tesseract or CuneiForm)
tool = pyocr.get_available_tools()[0]
# Load the image
img = Image.open(‘image_sample.png’)
# Extract text from the image
text = tool.image_to_string(img)
# Print the extracted text
print(text)

import boto3
# Initialize a Textract client
client = boto3.client(‘textract’)
# Path to the image or PDF file you want to analyze
file_path = ‘path_to_your_file.png’ # Replace with your file path
# Open the file in binary mode
with open(file_path, ‘rb’) as document:
# Call Textract to analyze the document
response = client.detect_document_text(Document={‘Bytes’: document.read()})
# Print the extracted text
for item in response[‘Blocks’]:
if item[‘BlockType’] == ‘LINE’:
print(item[‘Text’])
Conclusion
Choosing the right OCR library in Python depends on the specific use case, the language requirements, and the complexity of the documents you’re processing. Whether you’re working on historical documents, multilingual texts, or simple scanned PDFs, these libraries provide powerful tools for text extraction.
