我使用了来自 Kaggle 的道路标志检测数据集,链接如下:https://www.kaggle.com/andrewmvd/road-sign-detection 它由877张图像组成。这是一个相当不平衡的数据集,大多数图像属于限速类,但由于我们更关注边界框预测,因此可以忽略不平衡。 加载数据 每个图像的注释都存储在单独的XML文件中。我按照以下步骤创建了训练数据...
3. Object Detection with PyTorch [ code ] In this section, we will learn how to use Faster R-CNN object detector with PyTorch. We will use the pre-trained model included with torchvision. Details of all the pre-trained models in PyTorch can be found in torchvision.models Sounds interesting...
