| Detectron2 is Facebook AI Research's next generation software system | |
| that implements state-of-the-art object detection algorithms. | |
| It is a ground-up rewrite of the previous version, | |
| [Detectron](https://github.com/facebookresearch/Detectron/), | |
| and it originates from [maskrcnn-benchmark](https://github.com/facebookresearch/maskrcnn-benchmark/). | |

| ### What's New | |
| * It is powered by the [PyTorch](https://pytorch.org) deep learning framework. | |
| * Includes more features such as panoptic segmentation, densepose, Cascade R-CNN, rotated bounding boxes, etc. | |
| * Can be used as a library to support [different projects](projects/) on top of it. | |
| We'll open source more research projects in this way. | |
| * It [trains much faster](https://detectron2.readthedocs.io/notes/benchmarks.html). | |
| See our [blog post](https://ai.facebook.com/blog/-detectron2-a-pytorch-based-modular-object-detection-library-/) | |
| to see more demos and learn about detectron2. | |
