detectron2 README

The project's README from github.com/facebookresearch/detectron2. As one markdown file: README.md.

Detectron2 is Facebook AI Research's next generation library that provides state-of-the-art detection and segmentation algorithms. It is the successor of Detectron and maskrcnn-benchmark. It supports a number of computer vision research projects and production applications in Facebook.

Searching Database…

这是什么?Detectron2 是 Facebook AI Research 推出的新一代库,用于目标检测、分割以及其他视觉识别任务,内置最先进的算法。
它是一个我能直接运行的应用,还是一个用来做开发的库?是一个库:你在它之上搭建研究项目和应用程序,而不是把它当成独立程序来启动。
我怎么安装它并跑起第一个模型?按照安装说明安装,然后参考入门指南或官方 Colab Notebook,里面讲解了基本用法。
它是基于 PyTorch 运行的吗?是的——它基于 PyTorch:训练好的模型可以导出为 PyTorch 格式的 TorchScript,同时也支持导出到 Caffe2。环境要求请查看安装说明。
这是给研究人员用的,还是给生产系统用的?两者都是——它既支撑计算机视觉研究项目,也支撑 Facebook 内部的生产应用。
它涵盖哪些任务和模型架构?核心是目标检测和分割,此外还包括全景分割、Densepose、Cascade R-CNN、旋转边界框、PointRend、DeepLab、ViTDet 和 MViTv2。
它和最初的 Detectron 有什么不同?它是 Detectron 和 maskrcnn-benchmark 的新一代继任者,最大的改进是速度:训练快得多。
我在哪里能看到它的实际效果?README 里链接了一篇包含更多演示的博客文章,还有一篇讲述 detectron2 背后故事的访谈。
