                print("Video frame is empty or processing is complete.")
                break

            results = blurrer(im0)

            # print(results")  # access the output

## Real-World Applications

### Privacy Protection in Surveillance

[Security cameras](https://www.ultralytics.com/blog/the-cutting-edge-world-of-ai-security-cameras) and surveillance systems can use YOLO11 to automatically blur faces, license plates, or other identifying information while still capturing important activity. This helps maintain security while respecting privacy rights in public spaces.

### Healthcare Data Anonymization

In [medical imaging](https://www.ultralytics.com/blog/ai-and-radiology-a-new-era-of-precision-and-efficiency), patient information often appears in scans or photos. YOLO11 can detect and blur this information to comply with regulations like HIPAA when sharing medical data for research or educational purposes.

### Document Redaction

When sharing documents that contain sensitive information, YOLO11 can automatically detect and blur specific elements like signatures, account numbers, or personal details, streamlining the redaction process while maintaining document integrity.

### Media and Content Creation

Content creators can use YOLO11 to blur brand logos, copyrighted material, or inappropriate content in videos and images, helping avoid legal issues while preserving the overall content quality.

w, h, fps = (int(cap.get(x)) for x in (cv2.CAP_PROP_FRAME_WIDTH, cv2.CAP_PROP_FRAME_HEIGHT, cv2.CAP_PROP_FPS))

# Video writer
video_writer = cv2.VideoWriter("object_blurring_output.avi", cv2.VideoWriter_fourcc(*"mp4v"), fps, (w, h))

# Init ObjectBlurrer
blurrer = solutions.ObjectBlurrer(
    show=True,  # display the output
    model="yolo11n.pt",  # model="yolo11n-obb.pt" for object blurring using YOLO11 OBB model.
    blur_ratio=0.5,  # set blur percentage i.e 0.7 for 70% blurred detected objects
    # line_width=2,  # width of bounding box.
    # classes=[0, 2],  # count specific classes i.e, person and car with COCO pretrained model.
)

# Process video
while cap.isOpened():
    success, im0 = cap.read()
    if not success:
        print("Video frame is empty or processing is complete.")
        break
    results = blurrer(im0)
    video_writer.write(results.plot_im)

cap.release()
video_writer.release()
cv2.destroyAllWindows()
```

### What are the benefits of using Ultralytics YOLO11 for object blurring?

Ultralytics YOLO11 offers several advantages for object blurring:

- **Privacy Protection**: Effectively obscure sensitive or identifiable information.
- **Selective Focus**: Target specific objects for blurring, maintaining essential visual content.
- **Real-time Processing**: Execute object blurring efficiently in dynamic environments, suitable for instant privacy enhancements.

### Can I use Ultralytics YOLO11 to blur faces in a video for privacy reasons?

Yes, Ultralytics YOLO11 can be configured to detect and blur faces in videos to protect privacy. By training or using a pre-trained model to specifically recognize faces, the detection results can be processed with [OpenCV](https://www.ultralytics.com/glossary/opencv) to apply a blur effect. Refer to our guide on [object detection with YOLO11](https://docs.ultralytics.com/models/yolo11/) and modify the code to target face detection.

### How does YOLO11 compare to other object detection models like Faster R-CNN for object blurring?

Ultralytics YOLO11 typically outperforms models like Faster R-CNN in terms of speed, making it more suitable for real-time applications. While both models offer accurate detection, YOLO11's architecture is optimized for rapid inference, which is critical for tasks like real-time object blurring.
