## FAQ

### How can I use Ultralytics YOLO11 for real-time queue management?

To use Ultralytics YOLO11 for real-time queue management, you can follow these steps:

1. Load the YOLO11 model with `YOLO("yolo11n.pt")`.
2. Capture the video feed using `cv2.VideoCapture`.
3. Define the region of interest (ROI) for queue management.
4. Process frames to detect objects and manage queues.

Here's a minimal example:

```python
import cv2

from ultralytics import YOLO, solutions

model = YOLO("yolo11n.pt")
cap = cv2.VideoCapture("path/to/video.mp4")
queue_region = [(20, 400), (1080, 404), (1080, 360), (20, 360)]

queue = solutions.QueueManager(
    names=model.names,
    reg_pts=queue_region,
    line_thickness=3,
)

while cap.isOpened():
    success, im0 = cap.read()
    if success:
        tracks = model.track(im0, show=False, persist=True, verbose=False)
        out = queue.process_queue(im0, tracks)
        cv2.imshow("Queue Management", im0)
        if cv2.waitKey(1) & 0xFF == ord("q"):
            break

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

### Can Ultralytics YOLO11 handle multiple types of queues, such as in airports and retail?

Yes, Ultralytics YOLO11 can manage various types of queues, including those in airports and retail environments. By configuring the QueueManager with specific regions and settings, YOLO11 can adapt to different queue layouts and densities.

Example for airports:

```python
queue_region_airport = [(50, 600), (1200, 600), (1200, 550), (50, 550)]
queue_airport = solutions.QueueManager(
    names=model.names,
    reg_pts=queue_region_airport,
    line_thickness=3,
)
```
