要实现Cascade Mask R-CNN,我们需要遵循一系列步骤来准备环境、获取数据、构建模型、进行训练和评估。以下是一个详细的指南,包括必要的代码片段。 1. 准备Cascade Mask R-CNN所需的环境和库 首先,我们需要安装必要的Python库,包括深度学习框架(如PyTorch或TensorFlow)、MMdetection(一个基于PyTorch的目标检测工具箱,它...
在原始出版物之后,Cascade R-CNN 已在许多不同的代码库中成功复制,包括流行的检测器 [20]、PyTorch1 和 TensorFlow2,显示了独立于实现代码库。在此扩展版本中,我们将cascade R-CNN 扩展为实例分段,将掩码头添加到级联中,表示为级Cascade mask RCNN。这表明,与流行的maskR-CNN[25],实现非平凡的改进。还提出了...

4. Experiments All experiments are conducted in PyTorch with one NVIDIA A100 GPU. For a fair comparison with prior works, we use the first four residual blocks (conv1∼conv4) of ResNet-50 [15] as the backbone and resize the images to 900 × 1500 as the input. 4.1. Datasets We...
This idea can be applied to any detector based on the two-stage R-CNN framework, including Faster R-CNN, R-FCN, FPN, Mask R-CNN, etc, and reliable gains are available independently of baseline strength. A vanilla Cascade R-CNN on FPN detector of ResNet-101 backbone network, without ...
