How to Use the YOLOv8 Class List in Object Detection π οΈ
To effectively utilize the YOLOv8 model and its class list, it is crucial to understand how to implement it in various environments. Hereβs a step-by-step guide to get you started:
Step 1: Setting Up Your Environment
-
Install Required Libraries: Begin by setting up your Python environment. Make sure to install all necessary libraries such as
opencv-python
,numpy
, and the YOLOv8 model. -
Prepare Your Dataset: Depending on your detection task, gather and annotate your images if necessary. The class list can guide you on what objects to include.

Use the following code snippet to load the YOLOv8 model:
import cv2
from yolov8 import YOLO
model = YOLO('path_to_yolov8_weights')
Step 3: Preprocessing the Input
Preprocessing involves resizing the images and ensuring they are in the correct format:
image = cv2.imread('path_to_image')
image_resized = cv2.resize(image, (640, 640)) # Resize to model input size
Step 4: Making Predictions
To make predictions, run the following code:
results = model.predict(image_resized)
Step 5: Visualizing Results
You can visualize the detection results as follows:
for detection in results:
class_id = detection['class_id']
confidence = detection['confidence']
box = detection['box']
# Draw bounding box on original image
cv2.rectangle(image, (box[0], box[1]), (box[2], box[3]), (255, 0, 0), 2)
cv2.putText(image, f'{class_id}: {confidence:.2f}', (box[0], box[1]-10), cv2.FONT_HERSHEY_SIMPLEX, 0.5, (255, 0, 0), 2)
Step 6: Displaying the Output
Finally, display the processed image with detected objects:
cv2.imshow('Detected Objects', image)
cv2.waitKey(0)
cv2.destroyAllWindows()
