  • Run Object Detection: Use the detect method to perform object detection on an image:
results = model.detect("path/to/image.jpg")

          Replace “path/to/image.jpg” with the path to the image you want to analyze.

  • Access Results: The results variable will contain information about the detected objects, including their classes, confidence scores, and bounding box coordinates.

for result in results:

print(f"Class: {result['class']}, Confidence: {result['confidence']}, Bounding Box: {result['bbox']}")

         Adjust the code as needed based on your specific use case.

           By following these steps, you can easily integrate YOLOv8 into your Python projects for efficient and accurate object detection

What is YOLOv8?

YOLOv8 is the latest version of the popular YOLO (You Only Look Once) model series, known for its ability to quickly and accurately detect objects in images and videos. With each update, the technology improves, and YOLOv8 is no exception—it’s designed to be faster and more accurate than ever.

This model is perfect for real-time video stream tasks like identifying people, vehicles, or objects. It’s beneficial in areas like self-driving cars and security systems, where split-second decisions are crucial. YOLOv8 is setting a new standard for speed and accuracy in object detection.

Who Created YOLOv8?

Glenn Jocher, a computer vision and machine learning leader, developed YOLOv8. As the founder of Ultralytics, Glenn and his team have been behind all the YOLO models, and they’ve become a go-to choice for real-time object detection tasks.

With YOLOv8, Glenn and the Ultralytics team have taken the improvements from previous versions and made the model even more efficient and powerful, pushing the limits of what’s possible in object detection.

A Quick History of YOLOv8

The YOLO journey started in 2016. Joseph Redmon and Santosh Divvala introduced a new way of detecting objects in images by processing them in one go, making it both fast and accurate. Here’s how the series has evolved:

  • YOLOv2 (2017): Known as YOLO9000, this version improved accuracy and performance by adding features like batch normalisation and the Darknet-19 backbone.
  • YOLOv3 (2018): This version introduced multi-scale predictions, allowing it to detect objects of different sizes more effectively.
  • YOLOv4 (2020): YOLOv4 introduced new techniques, like CSPDarknet53, making it faster and better at handling complex tasks.
  • YOLOv5 (2020): Although not officially part of the YOLO series, YOLOv5, developed by Ultralytics, became famous for its ease of use and better training features.
  • YOLOv6 (2022): Released by Meituan, YOLOv6 made further improvements in speed and efficiency.
