What is YOLOv8 Inference, and How Does It Work?
YOLOv8 inference is the process of using a trained model to detect objects in images and videos. The model does not learn new things during inference. It only applies what it has already learned.
Inference is an essential step in object detection. It helps the model analyze new data and find objects in real time. YOLOv8 is fast and accurate, making it perfect for tasks like security, traffic monitoring, and automation.
Understanding Inference in YOLOv8
Inference means running a trained model on new images or videos. Unlike training, which teaches the model, inference only makes predictions. The model looks at a picture, finds objects, and labels them.
For example, if you give a YOLOv8 model a street photo, it will detect cars, people, and traffic lights. It draws boxes around objects and gives them names. Each object has a confidence score, showing how sure the model is.
How YOLOv8 Detects Objects in Images and Videos
When you Run YOLOv8 inference on images and videos, the model first resizes the image to fit the input requirements. It then scans different areas to detect objects, labeling them and providing results in just milliseconds. This speed makes YOLOv8 one of the fastest object detection models available.
When you Run YOLOv8 inference on images and videos, each video frame is processed individually. It detects moving objects and tracks them across frames, enabling real-time applications like self-driving cars and security cameras. Using a GPU can significantly speed up the process.

After installing these tools, you need to check if everything is working. Running a simple command can confirm that YOLOv8 is appropriately installed. If you are using Google Colab, make sure your runtime is set to GPU mode for better performance. A proper setup helps avoid errors and slow performance.
Loading a Pre-Trained YOLOv8 Model for Object Detection
Once you’re ready to Run YOLOv8 inference on images and videos, the next step is to load a trained model. These models are already designed to detect common objects like people, cars, and animals. Using a pre-trained model saves time compared to training from scratch.
After you’re ready to Run YOLOv8 inference on images and videos, the model will begin detecting objects. It processes each image and adds bounding boxes with labels to highlight the detected items. This step ensures better accuracy and faster results for real-time object detection.
