Support Ukraine - Help Provide Humanitarian Aid to Ukraine. 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](https://github.com/facebookresearch/Detectron/) and [maskrcnn-benchmark](https://github.com/facebookresearch/maskrcnn-benchmark/). It supports a number of computer vision research projects and production applications in Facebook.

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. ## Installation See [installation instructions](https://detectron2.readthedocs.io/tutorials/install.html). ## Getting Started See [Getting Started with Detectron2](https://detectron2.readthedocs.io/tutorials/getting_started.html), and the [Colab Notebook](https://colab.research.google.com/drive/16jcaJoc6bCFAQ96jDe2HwtXj7BMD_-m5) to learn about basic usage. Learn more at our [documentation](https://detectron2.readthedocs.org). And see [projects/](projects/) for some projects that are built on top of detectron2. ## Model Zoo and Baselines We provide a large set of baseline results and trained models available for download in the [Detectron2 Model Zoo](MODEL_ZOO.md). ## License Detectron2 is released under the [Apache 2.0 license](LICENSE). ## Citing Detectron2 If you use Detectron2 in your research or wish to refer to the baseline results published in the [Model Zoo](MODEL_ZOO.md), please use the following BibTeX entry. ```BibTeX @misc{wu2019detectron2, author = {Yuxin Wu and Alexander Kirillov and Francisco Massa and Wan-Yen Lo and Ross Girshick}, title = {Detectron2}, howpublished = {\url{https://github.com/facebookresearch/detectron2}}, year = {2019} } ```
