RectLabelis an offline image annotation tool for object detection and segmentation. Although this is not an open source program, with RectLabel, you can label polygons and keypoints in the YOLO format. A visibility flag v defined as v=0: not labeled, v=1: labeled but not visible, and v...
All YOLOv8 pretrained models are available here. Detection and Segmentation models are pretrained on the COCO dataset, while Classification models are pretrained on the ImageNet dataset. Modelsdownload automatically from the latest Ultralyticsreleaseon first use. ...
Training a YOLOv8 model can be done using either Python or CLI. Below are examples for training a model using a COCO-pretrained YOLOv8 model on the COCO8 dataset for 100epochs: Example PythonCLI fromultralyticsimportYOLO# Load a COCO-pretrained YOLOv8n modelmodel=YOLO("yolov8n.pt")# T...

从上面可以看出,YOLOv8 主要参考了最近提出的诸如 YOLOX、YOLOv6、YOLOv7 和 PPYOLOE 等算法的相关设计,本身的创新点不多,偏向工程实践,主推的还是 ultralytics 这个框架本身。
