The YOLOv8 series offers a diverse range of models, each specialized for specific tasks in computer vision. These models are designed to cater to various requirements, from object detection to more complex tasks likeinstance segmentation, pose/keypoints detection, oriented object detection, and classi...
SegmentationValidator 类是这个文件的核心,它继承自 DetectionValidator。在初始化方法中,设置了任务类型为“分割”,并初始化了分割指标。这个类的实例可以通过传入模型和数据集的参数来创建,并通过调用实例来执行验证。 在preprocess 方法中,输入的批次数据会进行预处理,将掩码转换为浮点数并发送到指定的设备上。init_me...
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。

④Segmentation做更细化的 a、分类:输出类别 b、目标检测:输出矩形框(位置)和类别 c、语义分割:把每个像素的类别输出,但不区分不同物体的像素 d、实例分割:可以区分同一类别不同物体的像素。无人驾驶要对全景做实例分割。 1.2 目标检测的两个阶段—单阶段和双阶段 ...
