Welcome to the fascinating world of object detection with YOLOv8! In this article, we will guide you through the installation and usage of this cutting-edge model from Ultralytics. Whether you’re venturing into the realms of object detection, image segmentation, or image classification, YOLOv8 has something to offer you. Let’s dive right in!

What is YOLOv8?

Ultralytics YOLOv8 is a state-of-the-art model built on the success of its predecessors, introducing new features and performance enhancements. It is designed for speed and accuracy, making it an excellent choice for a variety of computer vision tasks.

Installation Steps

1. Clone the repository:

git clone https://github.com/akanametov/yolov8-face

2. Install required packages:

pip install ultralytics

3. Go to the code folder:

cd yolov8-face

Trained Models

Various trained models are available for your tasks:

• yolov8n-face.pt
• yolov8m-face.pt
• yolov8l-face.pt
• yolov8n-person.pt
• yolov8n-football.pt
• yolov8m-football.pt
• yolov8n-parking.pt
• yolov8m-parking.pt
• yolov8n-drone.pt
• yolov8m-drone.pt

Performing Inference

Let’s perform object detection on images using the trained models.

For example, to detect faces using yolov8n-face.pt:

yolo task=detect mode=predict model=yolov8n-face.pt conf=0.25 imgsz=1280 line_thickness=1 max_det=1000 source=examples/face.jpg

Similarly, you can use the models for detecting persons, footballs, and drones by specifying the appropriate model.

Results Analysis

The inference results can be analyzed through parameter curves and confusion matrices. These metrics will provide insights into how well the model is performing.

Training Models

To train a model using your own dataset:

yolo task=detect mode=train model=yolov8n.pt data=datasets/data.yaml epochs=100 imgsz=640

Troubleshooting

If you encounter issues during installation or execution, here are some troubleshooting tips:

• Missing Packages: Ensure that all required packages are installed. Use pip install -r requirements.txt if provided.
• Model Not Found: Double-check the path to the model file. Make sure you have downloaded it correctly.
• Low Accuracy: Review your dataset; ensure it is correctly formatted and sufficiently large.
• Performance Issues: Adjust the imgsz parameter according to your hardware capabilities.
