YOLO目标检测算法简介** YOLO(You Only Look Once)是一种单阶段目标检测算法,它将目标检测任务转化为一个回归问题,通过一次网络前向传播即可获得目标的位置和类别信息。与传统的双阶段算法相比,YOLO具有速度快、精度高的特点。 YOLO算法的核心思想是将输入图像划分为网格,每个网格负责检测该区域内的目标。每个网格会预测多个边界框和对应的置信度,置信度表示该边界框包含目标的概率。最后,通过非极大值抑制(NMS)算法去除冗余边界框,得到最终的检测结果。 YOLO算法自提出以来,已经发展出多个版本,包括YOLOv1、YOLOv2、YOLOv3和YOLOv4。每个版本都在准确率和速度方面进行了改进,使其成为目前最流行的目标检测算法之一。 # 2.
