# Detect faces faces = face_cascade.detectMultiScale(image, scaleFactor=1.1, minNeighbors=5)

# Blur each detected face for (x, y, w, h) in faces: face = image[y:y+h, x:x+w] blurred_face = cv2.GaussianBlur(face, (55, 55), 0) image[y:y+h, x:x+w] = blurred_face

# Save the result cv2.imwrite(‘blurred_photo.jpg’, image) “`

Key Takeaways

By mastering these methods, you can ensure privacy and anonymity in your photos while maintaining their visual appeal. Whether you’re a casual user or a tech enthusiast, there’s a face-blurring solution that fits your needs.
