# Object Counting using Ultralytics YOLOv8 🚀
|
||
|
|
|
||
|
|
## What is Object Counting?
|
||
|
|
|
||
|
|
Object counting with [Ultralytics YOLOv8](https://github.com/ultralytics/ultralytics/) involves accurate identification and counting of specific objects in videos and camera streams. YOLOv8 excels in real-time applications, providing efficient and precise object counting for various scenarios like crowd analysis and surveillance, thanks to its state-of-the-art algorithms and deep learning capabilities.
|
||
|
|
|
||
|
|
## Advantages of Object Counting?
|
||
|
|
|
||
|
|
- **Resource Optimization:** Object counting facilitates efficient resource management by providing accurate counts, and optimizing resource allocation in applications like inventory management.
|
||
|
|
- **Enhanced Security:** Object counting enhances security and surveillance by accurately tracking and counting entities, aiding in proactive threat detection.
|
||
|
|
- **Informed Decision-Making:** Object counting offers valuable insights for decision-making, optimizing processes in retail, traffic management, and various other domains.

## Example
|
||
|
|
|
||
|
|
```python
|
||
|
|
from ultralytics import YOLO
|
||
|
|
from ultralytics.solutions import object_counter
|
||
|
|
import cv2
|
||
|
|
|
||
|
|
model = YOLO("yolov8n.pt")
|
||
|
|
cap = cv2.VideoCapture("path/to/video/file.mp4")
|
||
|
|
|
||
|
|
counter = object_counter.ObjectCounter() # Init Object Counter
|
||
|
|
region_points = [(20, 400), (1080, 404), (1080, 360), (20, 360)]
|
||
|
|
counter.set_args(view_img=True, reg_pts=region_points,
|
||
|
|
classes_names=model.model.names, draw_tracks=True)
|
||
|
|
|
||
|
|
while cap.isOpened():
|
||
|
|
success, frame = cap.read()
|
||
|
|
if not success:
|
||
|
|
exit(0)
|
||
|
|
tracks = model.track(frame, persist=True, show=False)
|
||
|
|
counter.start_counting(frame, tracks)
|
||
|
|
```
|
||
|
|
|
||
|
|
???+ tip "Region is Moveable"
|
||
|
|
|
||
|
|
You can move the region anywhere in the frame by clicking on its edges
|
||
|
|
|
||
|
