Step 1: Install Required Libraries
You will need captcha
for generating CAPTCHA images, and pytesseract
(OCR tool) to read the text from the images.
Install them via pip:
pip install captcha pytesseract pillow
Step 2: Generate CAPTCHA Image Using ImageCaptcha
First, let's see how to generate a simple CAPTCHA image using the captcha
library.
Example Code to Generate CAPTCHA:
from captcha.image import ImageCaptcha
# Create an ImageCaptcha object
image_captcha = ImageCaptcha()
# Define the text that you want in the CAPTCHA image
captcha_text = 'ABCD'
# Generate the CAPTCHA image
captcha_image = image_captcha.generate_image(captcha_text)
# Save the image to a file
captcha_image.save('captcha_image.png')
# Optionally, display the image
captcha_image.show()
#This script will create a simple CAPTC
This script will create a simple CAPTCHA image with the text'ABCD'
and save it ascaptcha_image.png
.
Step 3: Read CAPTCHA Image Using OCR (pytesseract
)
Now that you've generated a CAPTCHA image, you can use pytesseract
to read the text from the image.
Example Code to Read CAPTCHA:
from PIL import Imageimport pytesseract# Path to the tesseract executable (you may need to adjust this depending on your OS)pytesseract.pytesseract.tesseract_cmd = r'C:\Program Files\Tesseract-OCR\tesseract.exe' # Windows path# Load the CAPTCHA imagecaptcha_image = Image.open('captcha_image.png')# Use pytesseract to extract text from the imagecaptcha_text = pytesseract.image_to_string(captcha_image)# Print the extracted textprint("Extracted CAPTCHA Text:", captcha_text.strip())
