YOLOv8 Instance Segmentation: A State-of-the-Art Approach to Object Detection


YOLOv8 is the latest version of the YOLO object detection framework, known for its speed and accuracy. Released in January 2023, YOLOv8 introduces a range of new features that make it faster and more accurate than previous versions. One of the significant enhancements is the inclusion of instance segmentation capabilities, allowing YOLOv8 to not only detect objects in images but also accurately segment them.


YOLOv8 incorporates several key architectural features that contribute to its advanced performance:

Modified Backbone Network

YOLOv8 uses a modified version of the ResNet50 network as its backbone. This deeper and wider backbone network enables the extraction of more informative features from the input image, enhancing the model's detection and segmentation capabilities.

Improved Classification Head

YOLOv8 introduces an enhanced classification head based on the Feature Pyramid Network (FPN). This classification head improves the accuracy of object classification, leading to more precise instance segmentation results.

Other Enhancements

YOLOv8 incorporates additional improvements, such as a new objectness score, a refined loss function, and an optimized training schedule. These enhancements further contribute to YOLOv8's state-of-the-art performance in object detection and instance segmentation.
