1. LabelImg 1)LabelImg 是一款开源的图像标注工具,标签可用于分类和目标检测,它是用Python编写的,并使用Qt作为其图形界面,简单好用。注释以 PASCAL VOC 格式保存为 XML 文件,这是 ImageNet 使用的格式。 此外,它还支持 COCO 数据集格式。 2)安装方法: 前置条件:安装Python3以上版本,安装pyqt5 第一步:下载安装...
在R-CNN中使用了NMS来确定最终的bbox,其对每个候选框送入分类器,根据分类器的类别分类概率做排序(论文中称为greedy-NMS).但其实也可以在分类之前运用简单版本的NMS来去除一些框. 四、使用python来简单模拟一个NMS过程 代码语言:javascript 代码运行次数:0 运行 AI代码解释 # python3importnumpyasnp defpy_nms(de...
详细步骤: (1)安装Anaconda. 再创建使用 TensorFlow Object Detection API 的虚拟环境,如 conda create -n tensorflow_object_detection_api python=3.9 ,最后进入虚拟环境 conda activate tensorflow_object_detection_api (2)在当前虚拟环境下安装 TensorFlow :需安装 v2.2 以上版本。命令: pip install tensorflow (3...
