[C#]C# OpenVINO部署yolov8图像分类模型

【官方框架地址】

https://github.com/ultralytics/ultralytics.git
【算法介绍】

YOLOv8 抛弃了前几代模型的 Anchor-Base。

YOLO 是一种基于图像全局信息进行预测的目标检测系统。自 2015 年 Joseph Redmon、Ali Farhadi 等人提出初代模型以来，领域内的研究者们已经对 YOLO 进行了多次更新迭代，模型性能越来越强大。现在，YOLOv8 已正式发布。

YOLOv8 是由小型初创公司 Ultralytics 创建并维护的，值得注意的是 YOLOv5 也是由该公司创建的。
