YoloV1(anchor-based): 是官方第一版yolo模型,它使用单个卷积神经网络分支对单张图像直接做目标检测和分类,并不像R-CNN系列累的两阶段检测第一步先提取候选框(ROI, regions of interest),第二步再对这些候选框做分类.所以其速度比同期的二阶段模型低更快,但精度要低. yolov2, yolov3都是重点提升yolov1的检测...
YOLOv8 is a state-of-the-art object detection and image segmentation model created by Ultralytics, the developers of YOLOv5. Try the Model Use the widget below to experiment with YOLOv8. You can detect COCO classes such as people, vehicles, animals, household items. ...
